Dear Tom,
I own a 2005 GMC Envoy with 54,000 miles. It has a big engine and only gets 15.5 MPG. Although I love my Envoy, I did consider getting a new SUV (maybe a 4 cylinder) to get better mileage and performance, but I can’t afford to do that right now. I heard that there’s a special air filter that increases mileage and performance in vehicles. Is this true? If so, can you tell me what it is? Or is there is something else I could do? Thank you.
Joanie from West Seneca, NY

Joanie,
Yes, there is an air filter that will increase gas mileage and performance. It’s called K&N. Have one installed in your vehicle. In addition, make sure the tires are inflated properly and change the engine oil to synthetic oil. Finally, change the transmission fluid to synthetic, as well as all the differentials and transfer case. This action will also increase fuel mileage because you will reduce friction in these components by using synthetic lubricants. Best to you.
Tom

James,
The engine in your wagon is a 5.7-liter. No it is not a Corvette engine. The Kelly Blue Book value in “pristine condition” is $5,700. That’s all you can expect to get unless you find someone who can’t live without it and is willing to pay whatever you ask. Then you can click your ruby red slippers three times and say to yourself, “There’s no place like home” and then … wake up and smell the coffee. Come on, James! It’s a Buick station wagon!
Tom

Tina,
I have been buying gas from “the rez” for twenty years with not one problem. Over the years I have heard various comments about gasoline from the reservations. For example, it was rumored that the proprietors on the Indian Reservation were irresponsible and did not check their tanks, tank seals, or pump calibration. Also, they bought cheap gas that had water in it to resell to the public, and many other ridiculous accusations. Since my experience said otherwise, I decided to speak to JD, the manager of Seneca One Stop, in an attempt to understand why these rumors have reigned for years. He offered no reason as to why these rumors exist. However, he showed me the tests that Seneca One Stop goes through to ensure that their tanks are water free, do not leak, and pump gas accurately. He assured me that the quality of the gas they buy is the highest quality offered to the motoring public. He stated that, because of the negative perception, they were overly cautious to make sure they had no problems. I cannot speak for any other Indian fueling stations because I didn’t speak to anyone except Seneca One Stop. However I have purchased “Indian gas” from other proprietors and have never had a problem (unlike a few non-Indian stations I have experienced problems with and later confirmed water was indeed in the gas). Why the rumors? In our capitalistic system, businesses compete for our dollars, so sometimes they talk negatively about one another to get a let-up on their competition. That’s just the way of the world.
Tom

Brian,
I have never heard this urban legend. However, I can tell you that the head gasket on your Nissan engine is probably blown, and that your son probably overheated the engine and drove it in that state until the head gasket blew out. This explains why the engine coolant is disappearing. It is being drawn from the cooling system into the engine and out the tailpipe. Have a talk with you son. I am sure he will confirm this suspicion. Have the engine compression tested and a cylinder leak down test performed. These tests will identify which cylinder is leaking. Removal of the head and resurfacing is necessary before replacing the head gasket. Success to you.

Dear Tom,
I saw your article on AOL Autos regarding pre-purchase inspections and it was very helpful. I am thinking of purchasing a ‘73 Chevy P-10 (Original Ice Cream Truck), but it is in rough condition and needs restoration. It has some rust on the axle, brake lines, and leaf springs. The engine and engine block are coated with what looks like years of caked-on oil deposits. It has an aluminum body that is in decent shape visibly. I did not notice any leaks on the ground near or around the vehicle. I want to restore the vehicle for various events, but I don’t have much money. The work would be done the Restoration Company located in New Jersey (the truck is in Connecticut). Do you know a company that could do the type of pre-purchase inspection that you wrote about? Can it be done on location? The restoration company has recommended a compression test. Can this be done on-site? Any help would be greatly appreciated.
Paul from Cherry Hill, NJ

Paul,
Any competent repair facility can perform a pre-purchase inspection on this vehicle. All that’s required is a lift and some basic tools. Ideally, you also should have a compression test and a charging system analysis (so you can see if there are any electrically problems). I also recommend an oil pressure test to make sure there are no internal engine problems. The truck probably has point ignition, so a simple tach/dwell meter will reveal any glitches in the ignition system. Also, check the brakes, steering & suspension, and the brake / fuel lines for integrity as these tend to rust over the years. A trained tech, armed with a complete checklist, should be able to give you a good idea as to the vehicle’s integrity before you plunk down the cash-ola for the Good Humor Man’s former ride. Good luck to you.
Tom

Bobbi Ann,
What can I say? Your beloved “Heartbeat of America” has cardiac arrest. The engine has to be removed and either be replaced or rebuilt. I would replace it with a remanufactured engine from a company such as Jasper Engines, so that the new power plant will be just like a new one (and at less cost than rebuilding the old one). As for the tach racing up when you step on the gas, check the transmission fluid. If it’s low, top it off and see if that solves the problem. If the problem is solved then you have a leak that must be repaired. If the fluid is burnt and dark brown or black, the transmission probably needs to be replaced or rebuilt. Your Camaro has given you many years of reliable service, now it’s time to either refurbish it or put it out to pasture. Only you can make that decision. Best to you.
Tom

Rick,
Sounds like the car has a parasitic electrical occurring when the key is off. No, you should not have to turn everything off inside the vehicle when you exit. There is something draining the battery. Have the shop perform an electrical draw test to track down the cause of the drain. During this test, a DVOH (Digital Volt Ohm Meter) is hooked up to the battery. The tech will eliminate each circuit until the draw goes away, identifying the offending circuit. Then he/she will trace the circuit to find the cause of the draw. Good luck.

Dear Tom,
There is a low coolant warning on my ’99 Jeep Grand Cherokee that won’t go away even though I had the coolant serviced. Also, the carpet is wet and slimy on the front passenger floor. Any help would be appreciated.
Theresa from Palo Alto, CA

Theresa,
Have a cooling system pressure test performed on your Jeep. Specifically, have the service tech look for a leaking heater core. Hot water from the cooling system circulates through the heater core. This heat emanates from the core and is blown into the vehicle’s cabin by the fan (this is how the heater works). When the heater core springs a leak, water from the cooling system leaks into the vehicle’s cabin and coolant is lost, hence the cause of the low coolant warning light and the wet carpet. The fact that the water feels slippery tells me that it’s probably anti freeze. Prepare yourself for a hefty repair bill; heater core replacement is very labor intensive. Wish I had better news.
Tom

Daniel,
BMW is great when it comes to customer satisfaction, in this case, I’m sure BMW would help you. Your best bet is to contact the district zone rep for BMW and explain the situation to him/her. Show them your title of ownership and the recent bill of sale for the car and I’m sure they will make an exception to the rule in this case. Good luck!
Tom

Korinna,
The computer needs to be scanned for trouble codes. It has detected a problem with the engine when it’s wet outside and has set a code, turning the check engine light on. Once the computer has been scanned, the technician can perform a set of pinpoint tests to determine the defective part. My guess is that the tech will find multiple random misfires. The tech will probably mist down the engine compartment with a spray water bottle in an effort to duplicate the problem. You’ll probably find that the sparkplug wires need replacing. Best to you.
Tom

Clancy,
The squeak could be coming from the bushings in the control arms, dry ball joint/s, worn strut insulators, or bearings. Get the car up on a lift and have the front suspension checked out. Success to you.
Tom

Rich,
Ignition switch replacement is common on cars with some mileage, but to have so many switches malfunction in such a short period of time makes me wonder if there is another issue affecting the system. The body control module, main computer, the instrument cluster and their respective wiring are all involved in the starting system. It’s going to take some in-depth diagnostics to track down this little bugger! Find a good electrical diagnostician. It will probably serve you well to arrange to leave the car at the shop so they can experience the problem first hand when it occurs.
Tom

Taylor,
I understand your feelings about the truck. My father gave me my first car too and that car meant a lot to me (until I found a Camaro I wanted bad enough, then I traded the Pontiac in). Here’s what you should do. First off, hook a mechanical gauge to an oil gallery in the engine and run it to verify actual oil pressure. If it’s okay, then the vehicle probably has a problem with the oil pressure-sending unit (which is quite common on older vehicles), the wiring to it, or the gauge in the dash. If the oil pressure is found to be low, then the oil pan has to come down and the lower end inspected for worn bearings, oil pump, or the likes. In this case, you might want to employ the service of a professional tech to evaluate the engine before repairing or replacing it. Or, take out a book on engine overhaul and go to it, if you have the mechanical aptitude or inclination. I rebuilt my first engine at 16 years of age, so you’re ready! Call the show and let me know how it worked out. Good luck.
Tom

Dear Tom,
I was told that there is no advantage to using synthetic engine oil over conventional oil. I do not believe this is true. Also, I was told that conventional oil used with a stabilizer would accomplish the same thing as synthetic oil. Is this true? Thanks.
Nick from Bemus Pt, NY

Nick,
Whoever told you that synthetic motor oil has no advantages compared to conventional oil doesn’t know what he is talking about. Synthetic oil is more resistant to viscosity breakdown (loss of ability to flow and thus lubricate) from heat, friction, and chemical contamination (the hostile environment of an operating internal combustion engine). Synthetic oil was originally developed for use in aircraft to address the extreme operating environment of the jet engines. On the intake side, aircraft jet engines operate at very cold temperatures because of the rush of air, ambient temperatures, and venturi effect. On the exhaust side, the aircraft jet engine is very hot. Conventional oils simply did not stand up well under these conditions, so engineers designed a syntheticly fortified lubricating oil to avoid the problems associated with conventional petroleum lubricants. The new formula worked well, so AMSOIL founder and president Al Amatuzio (at the time, a jet fighter pilot in our armed forces) set out to develop synthetic motor oil suitable for automotive applications. The first synthetic engine oil for cars entered the market in 1972. Today’s synthetic oils flow better than petroleum oil in cold temperatures, providing internal protection during winter start up. Obviously, the quality of synthetic oil varies. In my opinion, based on the research I have seen, AMSOIL and Mobile One are number one and number two respectively. Finally, adding a stabilizer to conventional oil does not provide the same advantages as synthetic oils.
Tom

Steve,
The wiper arm has to be replaced. The tension spring (located inside the arm) keeps the wiper blade snug against the windshield glass. When the spring wears out, the wiper arm lifts off the glass. Replace the arm and problem solved!
Tom

Ed,
Small convex mirrors are a good addition to the driver’s side to eliminate blind spots. The passenger’s side mirror is already of the convex design, that’s why it says “Objects May Be Closer Than They Appear.” As for why carmakers don’t add convex mirrors on the driver’s side? Bottom line, cost. End of story.
Tom

Lois,
I checked my database for brake recalls on these vehicles and came up with nothing. Call your local dealer and give them your VIN (Vehicle Identification Number) to run in their database to make sure there’s no action from Chrysler on this condition. If not, perhaps you ran the brake shoes too long on the car, resulting in failure? Or, if they were replaced at one time or another, perhaps the shop used inferior shoes, causing the glue to crystallize that could result in shoe failure. It’s impossible to tell without seeing the old parts and the service history of the vehicle. Good luck.
Tom

Lloyd,
Check for a dislodged vacuum line, crossed wire, or an inadvertently grounded sparkplug electrode either from dirt in the air gap or from the electrode crushed down to the ground position. I’m sure you’ll find your problem in one of these areas. Best to you.
Tom

Sheila,
First, check the coolant level. It sounds like the coolant is low and an air bubble is circulating through the system. If it is low, then check for a coolant leak. If the level is good, then there could be a vacuum leak causing the air blend door to open and close on engine demand. Check the vacuum lines that feed the heater system. There’s a vacuum chamber in the engine compartment that stores vacuum for the heater system to draw on when needed. That chamber is usually made of plastic and it can crack, resulting in erratic heater blend door operation. I’m sure you’ll find your problem in one of there areas. Best to you.

It’s certainly not new that Toyota is having problems with their vehicles. Week after week the mainstream media seems to come out with a new “update,” much of it simply quoting old news. Let’s take a look at the facts regarding the Toyota recalls and useful information for owners of these vehicles.

The first set of recalls started with what is termed the Floor Mat Recall. In this recall Toyota determined that the gas pedals in some of their vehicles were getting hung up with the floor mats on the front driver’s side, causing unintended acceleration. The next recall was the Gas Pedal Recall. After depressing the gas pedal in some vehicles, it did not completely return to its original position. Next came the Prius/HS250h hybrid ABS Braking Recall, prompted by owners who complained that their ABS brakes felt like they weren’t working adequately. And finally, there is a minor recall of some Tacoma pickups for faulty front driveshafts on 4WD vehicles. There is also an investigation being launched into Corollas for malfunctioning power steering, but there is no recall to date.

Floor Mat Recall

Vehicles involved in the floor mat recall include (info from Toyota’s website):

• 2005-2010 Avalon
• 2007-2010 Camry
• 2009-2010 Corolla
• 2008-2010 Highlander
• 2009-2010 Matrix
• 2004-2009 Prius
• 2005-2010 Tacoma
• 2007-2010 Tundra
• 2009-2010 VENZA
• 2009-2010 Pontiac Vibe

Owners of vehicles covered by the floor mat recall should take out any removable driver’s floor mat and not replace it with any other floor mat until they receive the vehicle-based remedy.

After you receive a notification from Toyota that the recall remedy for your vehicle is available, you should take your vehicle to an authorized Toyota dealer. Dealer personnel have been specially trained to implement the following vehicle-based remedy:
Toyota service techs will either modify or replace the accelerator pedals on the subject vehicles to address the risk of floor mat entrapment, even when an older-design all weather floor mat or other inappropriate mat is improperly attached, or is placed on top of another floor mat. Floor surface modifications are also being considered and will be included in the remedy plan for any model for which it is deemed appropriate. For the Camry and Avalon models involved, the shape of the floor surface underneath will also be reconfigured to increase the space between the accelerator pedal and the floor.

Gas Pedal Recall

Toyota discovered that there was a problem with excessive friction buildup on the bottom of the gas pedal of certain vehicles. This condition can cause the gas pedal to stick and, in some instances, not return completely to the original position after being depressed. This recall is in full swing.

Toyota’s accelerator pedal recall is confined to the following Toyota Division vehicles (info from Toyota’s website):

• Certain 2009-2010 RAV4
• Certain 2009-2010 Corolla
• 2009-2010 Matrix
• 2005-2010 Avalon
• Certain 2007-2010 Camry
• Certain 2010 Highlander
• 2007-2010 Tundra
• 2008-2010 Sequoia

No Lexus Division or Scion vehicles are affected by this recall action. Also not affected are Toyota Prius, Tacoma, Sienna, Venza, Solara, Yaris, 4Runner, FJ Cruiser, Land Cruiser and Highlander hybrids and Camry hybrids. Highlander hybrids and Camry hybrids are not involved in this action. Further, Camry, RAV4, Corolla and Highlander vehicles with VINs that begin with “J” are not involved.

If you have noticed that your accelerator pedal is hard to depress, slow to return, or is not smooth during operation, the vehicle should be stopped at the nearest safe location, the engine shut off and a Toyota dealer contacted for assistance.

What if you experience a sticking accelerator pedal while driving?

Each circumstance may vary, and drivers must use their best judgment, but Toyota recommends taking one of the following actions:

If you need to stop immediately, the vehicle can be controlled by stepping on the brake pedal with both feet using firm and steady pressure. Do not pump the brake pedal as it will deplete the vacuum utilized for the power brake assist. Shift the transmission gear selector to the Neutral (N) position and use the brakes to make a controlled stop at the side of the road and turn off the engine. If unable to put the vehicle in Neutral, turn the engine OFF. This will not cause loss of steering or braking control, but the power assist to these systems will be lost. If the vehicle is equipped with an Engine Start/Stop button, firmly and steadily push the button for at least three seconds to turn off the engine. Do NOT tap the Engine Start/Stop button. If the vehicle is equipped with a conventional key ignition, turn the ignition key to the ACC position to turn off the engine. Do NOT remove the key from the ignition as this will lock the steering wheel.

Prius/HS250h ABS Brake Recall

(as it appears on Toyota’s website)

Toyota Announces Voluntary Recall on 2010 Model-Year Prius and 2010 Lexus HS 250h Vehicles to Update ABS Software

TORRANCE, Calif., February 8, 2010 – Toyota Motor Sales (TMS), U.S.A., Inc, today announced it will conduct a voluntary safety recall on approximately 133,000 2010 Model Year Prius vehicles and 14,500 Lexus Division 2010 HS 250h vehicles to update software in the vehicle’s anti-lock brake system (ABS). No other Toyota, Lexus, or Scion vehicles are involved in this recall.

The ABS, in normal operation, engages and disengages rapidly (many times per second) as the control system senses and reacts to tire slippage. Some 2010 model year Prius and 2010 HS 250h owners have reported experiencing inconsistent brake feel during slow and steady application of brakes on rough or slick road surfaces when the ABS is activated in an effort to maintain tire traction.

Toyota has responded to owner concerns with a running production change for 2010 Prius that was introduced last month, improving the ABS system’s response time, as well as the system’s overall sensitivity to tire slippage. The production change for the HS 250h is planned for later this month.

The recall will allow Toyota dealers to perform the software update on 2010 Prius vehicles sold prior to this running production change. Only Prius vehicles produced since May 2009 and all HS 250h vehicles are subject to this recall. First- and second-generation Prius vehicles use a different ABS system and are not involved in this campaign. The ABS system on the Lexus HS 250h is similar in design to the Prius. The software adjustment planned for HS 250h production and dealer modification is being finalized and will be announced very soon. Toyota will begin mailing letters to Prius owners included in this recall next week and HS 250h owners within the next few weeks, to let them know when to bring their vehicles into a dealership. Owners will only receive a letter if their vehicle is involved in the recall.

Are Toyota and Lexus bad cars?

I say a hearty NO! The Toyota Motor Company’s reputation is built on a foundation of quality and safety. I believe it is still the basis of the company today and Toyota is moving swiftly to address these issues. The bottom line? It is still a fine car in spite of the recent problems. Toyota will make good on the faulty cars and will rebound as a safety and quality leader again in an effort to regain market dominance. Quite frankly, I think now is a great time to buy a Toyota. Last week, according to Kelly Blue Book, Toyota pricing had dropped an average of 4% across the board. This means a savings of $350 to $700, in addition to the 0% financing (which you never saw until now for a Toyota product). And look for other incentives in the near future to entice buyers back into the showrooms. As I see it, there will be some pretty good deals out there for some fine automobiles.

Well, that’s pretty much the skinny on the Toyota recalls. Call your local Toyota dealer with your VIN number so they can input it into Toyota’s database to see if your vehicle is involved in any of these actions. Or you can go online to: Pressroom.Toyota.com and you will find updates as they come hot off the press. Hope this helps clear things up a bit.

Dear Tom,
I purchased a used 2007 Dodge Caravan SXT – V6 with 21,000 miles. It gets 19 MPG in the city and only 20 MPG in the country. What can I do to get better mileage? I follow your advice for maintenance and welcome your advice. Thanks.
Ruth from Hamburg, NY

Ruth,
Fuel mileage is subjective to the driving environment, how the vehicle is driven, how it is maintained, and what kind of work it performs. First, make sure the performance system is up to snuff (sparkplugs & wires, air and fuel filter, breather element, and anything else related to the performance system). If these items are not replaced at the proper intervals, fuel mileage will suffer. Based on the low mileage of this vehicle, the plugs could be “carboned up” from lack of use. Have them cleaned and re-gapped. What else can you do to increase gas mileage? Inflate the tires to max inflation rate so they offer less rolling resistance; replace the air filter with a high flow filter like a K&N; and replace the engine oil, transmission fluid, and differential lubricants with synthetic lubricants. All this coupled with maintaining the performance system should net you a few more miles per gallon. Best to you.
Tom

Lee,
If what you outlined here is accurate, then I agree with you. It is entirely too much oil consumption for this engine. Excessive oil consumption is the result of poor piston ring sealing, bad valve guide seals, or sloppy valve guides. If the PCV system were clogged with sludge, then the crankcase would be pressurized. In this case, the oil would be pushed up into the breather system and into the air intake to be burned. Call John Domagala at the NFADA (Niagara Frontier Dealer’s Assoc). He is the director of AUTOCAP (Automotive Consumer Action Program) and John will get the Chrysler Zone Rep involved. Hopefully you will get some satisfaction. John’s number is 716-631-8510. Tell him I told you to call. Success to you.
Tom

Amy,
Let’s deal with one thing at a time. (1) The sloppy ignition key issue is probably due to a worn lock cylinder in the steering column. This requires replacement of the lock/key (removal of the steering wheel and air bag are part of this procedure to access the necessary parts). (2) The wipers have to be checked for a bad internal motor ground or (if so equipped) the wiper delay could be bad (3) The whirring sound by the belt could be a bad serpentine idler, an alternator or power steering pulley, or worn bearings in the water pump shaft. Get it into a shop that can address your concerns … one at a time. Good luck.
Tom

Lillie,
You give me no year, make, or model so my answer will be in general. The first thing that comes to mind is the thermostat. When it goes bad it can either stick closed (causing overheating) or open. If stuck open, the engine doesn’t get hot and thus the heater doesn’t get warm. Also, heater malfunction can also be caused by a problem with a duct door (these doors direct the heated air into the vehicle’s cabin). Finally, in the case of climate-controlled systems, a faulty electronic control module can cause heater malfunction. Hope this helps.
Tom

Randy,
Check the inner axle shaft CV joints. Heavy vibration occurs when they get worn and loose, especially under acceleration. Other common causes of front-end vibration include: loose/worn struts and/or strut bearing plates, loose ball joints, tie rod ends, rack mounts, or internally worn rack. Success to you.

Dear Tom,
I own a ‘88 Mazda RX7 rotary car. I stabilized the gas and backed it into a dry cold garage for storage over the winter. Will this be okay, or should I start the car once in a while?
Mike from Buffalo

Mike,
I like to start a vehicle that’s sitting over the winter at least twice a month and drive it at least once a month, if possible. Why? To keep seals and mating surfaces lubricated. If left too long without running, seals dry up and mating surfaces (when started dry in an engine that’s lost its oil prime) suffer premature wear. In addition, engines, transmissions, and drivetrain components operate better when not deprived of the precious lube they’ve come to rely upon for proper operation. Start two times each month, warm to operating temperatures, and drive when possible. This regimen will ensure that your Mazda keeps going HUMMMMMMMMMMM!
Tom

Bob,
I checked my ALLDATA database for anything pertaining to a no-start condition with this truck and found nothing. An engine needs three things to start: fuel, ignition, and air. Start with an ignition system check: coils, sparkplugs, and wires. If nothing is evident in the visual inspection, then do a computer scan in order to see if there are any codes in the memory. If the system is clean of codes, then the next step is a fuel system check. Hook a fuel pressure gauge to the fuel rail in the injection system. If fuel pressure is low then the fuel pump could be bad or you could have a plugged fuel filter. If the fuel system is found to be in good working order, then further engine diagnostics are in order to find out if it has proper compression and that the valve timing is in order. You should find the cause of your no-start condition in one of these areas. Good luck.
Tom

Tom,
No poltergeist here. You probably have a bad starter motor. When the armature shaft bushings wear out inside the starter, the armature is allowed to drag on the field windings. This condition eventually causes an electrical dead spot (or zone) to develop in the starter. Sometimes the armature lands on this dead zone after starting the engine, resulting in a no-start condition when you turn the key. Then like magic, after turning the key several times, the armature gets slightly bumped by the solenoid cycling and, like magic, the starter works. Have the starter removed and bench tested. Best to you.
Tom

Bunny,
You did not give me year, make, or model vehicle so my answer will be in general. No, shifting from drive to neutral will not do any internal damage to an automatic transmission. The only thing I can think of that could be affected would be premature shift cable or linkage failure from constant shifting. Otherwise your friend may shift away to his heart’s content!
Tom

Pooh,
Check the transmission fluid level. If it’s low, fill it to the fill line and drive it. If the problem is solved, then low fluid was the cause and you have to find the leak and fix it. If it still slips after filling the fluid, then there’s a problem inside the transmission. Perhaps the low fluid level caused internal damage to the bands or clutches. Also, check the fluid color; It should be red and clean. If it’s dark brown or black the unit has been overheated and might need rebuilding. Success to you.

Dear Tom,
There is a scrubbing noise coming from the left rear of my Toyota Camry LE. I had it checked out but they can’t find anything wrong. Please help! It sounds like some part is rubbing against another part. When I drive into my driveway it gets louder. When I am driving down the road, it is not as loud but I can still hear it.
Mary from Philadelphia, PA

Mary,
You didn’t tell me the year of your Camry LE so I could only guess that it is an ’02 or older, because that was the last year Camry was made with an LE trim. Also, that car came with either 4 wheel disc brakes or disc/drum combination. In either case I would check the emergency brake cable to see if it’s frozen. A frozen cable will keep the rear brake/s applied. I would also check the backing plates on the rear, as both types of systems have backing plates that could bend and rub against the disc or drum. Finally, I would check for a bad rear suspension spring or strut that could be causing the body to come down on the tire/s when going over a curb or bump. That’s the best info I can give you because I don’t know the year of your car. Success to you.
Tom

Rich,
According to my ALLDATA database, the door lock mechanism is roughly $135. As for labor, it’s only an hour for each door. I would get a breakdown of the repair, specifically the labor. Where do they justify the additional $320? If they stand firm on the estimate given, then they are charging way too much for the lock replacement and I would consult a AAA Approved Auto Repair Facility that specializes in foreign car repairs. You can find one through your local AAA club.
Tom

Cookie,
Your description of Emeril was superb! Have the struts and strut mounts checked. It sounds like they are worn out. I would also check the sway bar bushings because, when they wear out, the sway bar can bang on the underside of the car, especially when going over bumps. As for a shop you can trust, consult your local AAA Club for a AAA Approved Repair Facility in your area. Success to you.
Tom

Kathleen,
The following TSB was issued from Ford on this very issue for your car:

ACTION Inspect and seal cowl area and install Rain-Hat Extension Seal. Inspect and replace blower motor and/or blower motor resistor if there is evidence of water/corrosion.
Take it to your local dealer to have this service performed and the rain hat installed to stop water from entering the blower motor case; this will stop your problem. Best to you.
Tom

Steven,
Given the labor intensive nature of this operation (6 hrs according to the book) plus the cost of the evaporator ($432) and the cost of new refrigerant and an oil charge, plus evacuation and reclaiming the system, I understand why it is so expensive. Short of doing it yourself, I doubt you will find a better price (much less anyone willing to embark on disassembling your dashboard to replace the evaporator). Try your local AAA club to find a AAA Qualified Repair Facility near you to give you another quote. And remember, cheaper is not necessarily better. The shop must have the equipment, tools, and know-how to perform such an operation… and for that you pay.

Dear Tom,
I own a ’94 Mitsubishi 3000GT-SL with 121,000 miles. At about 95 – 100,000 miles it started burning oil (no leaks obvious) with blue smoke in the exhaust on startup. In the last couple of months the oil consumption is rapidly increasing. On “general principles” I replaced the PCV valve recently to no avail. On a bulletin board for these cars, there has been talk of valve oil seal problems. Could the seals get to the point where they fail completely and oil consumption take a sudden leap?
Spencer from Australia (Down Under)

Spencer,
Yes, seals could harden and break up, causing oil consumption to accelerate greatly as oil spills down the valve stems and into the combustion chambers to be burned. Pull a valve cover and inspect the valve seals. It’s time to delve deeper into engine diagnostics with cylinder leak-down and compression testing.
Good luck, mate!
Tom

Spencer asks a question that many vehicles experience, namely oil consumption at high mileage. What are the causes? What diagnostic tests should be performed?

Causes of oil consumption

Bad valve seals: The valves are located in the cylinder head above the combustion chamber. Oil is pumped at 50 to 80 psi of pressure into the top of the head, lubricating the valve-train. The valves have seals that stop the flow of oil down into the engine when the valve is open. If the seals fail, oil flows down into the combustion chamber and is burned.

Worn valve guides: The valves are guided by a small cylindrical chamber called a valve guide. These guides wear over time causing eccentricity (slop). The excess gap allows oil to flow down the valve stem and into the combustion chamber to be burned. You might be wondering why the valve seals don’t stop the oil. Because the gap is too large for the seal to work.

Pressurized crankcase due to clogged PCV or breather system: Your car’s engine is a giant pump, therefore it must breathe. The PCV (Positive Crankcase Ventilation) system does just this; it allows the engine to exhaust the excess crankcase pressure that builds up (a natural phenomenon of the internal combustion engine). These gases are captured and fed back into the engine to be burned. Carbon (a by-product of engines) can build up in the PCV system, clogging the breathing passages. This, in turn, pressurizes the oil pan and pushes oil up into the fuel delivery system, where it is fed into the engine and burned.

Blow-by from worn piston rings: The pistons in your car’s engine have seals around them in the form of rings. These rings have two functions: (1) They seal the combustion chamber so that the precious power produced from the firing of the cylinder is not lost. (2) They provide vital lubrication to the cylinder walls. When the rings wear out the pressure from combustion reverses down into the oil pan. Pressure in the oil pan forces oil into the valve covers, through the breather system, back into the fuel delivery system, and into the engine to be burned.

Tracking down the cause of oil consumption

PCV system: Remove the PCV valve with the engine running. There should be a strong vacuum pulling on the valve. If there is no vacuum, the system is clogged with sludge and carbon. It should be cleaned and the valve replaced.

Valve stem seals and guides: Remove the valve cover and shine a strong light on each valve stem. If the seals are gone, then further inspection is warranted. Pressurize the cylinder and remove the valve spring to closely inspect for a worn valve guide evidenced by broken-up valve stem seals).

If nothing is found after checking for a clogged PCV system and valve stem seals & guides, then run a cylinder leak-down test. In this test, each cylinder is charged with 120 lbs of compressed air and the engine is monitored to determine where the air is escaping from the cylinder. If air is escaping from the crankcase, then the piston rings are worn. You can also perform a compression test. Remove the spark plugs and test each cylinder individually for the total PSI of compression. If you find that one cylinder is low, then wet test it. To wet test the cylinder, remove the gauge, squirt oil into the cylinder, and then retest it. If the compression in that cylinder comes up, then that cylinder has worn piston rings. How do we know this? Because when oil was squirted into the cylinder, it filled the gap between the worn rings and cylinder wall, sealing the ring gap and thus increasing compression. In this is the case, consider rebuilding or replacing the engine.

Dear Tom,
I own a 2006 Malibu LS. I recently had the front and rear rotors and pads replaced, as well as the rear calipers. About 750 miles later the brakes started squealing. The pads cost $50 each; the rotors were $46 each; the calipers were $79 each. I brought the car back to shop at once and they cleaned the brakes. However, they are still squealing. Any solutions?
Joe from Long Island

Joe,
Brake squeal is a common problem and the result of a high-pitched vibration of the pad/s. Either the pad anti-rattle clips are worn/broken or the pad insulators were not installed at the time of the brake job. Get the vehicle back to the shop and have these checked. Best to you.
Tom

Michael,
Yes, your driving pattern is a textbook case for using synthetic motor oil. When a vehicle sits without being driven much, acid and moisture accumulate in the crankcase, causing erosion of the main and rod bearings. Good synthetic motor oil guards against chemical and moisture contamination because of the chemically fortified base stock. I recommend either AMSOIL or Mobil One, (number one and two).
Tom

Don,
You will have to water-test the car’s body to find the leak. Get in the car with a light and have someone soak down the body with a water hose at the point where you think the water is entering the vehicle. Use the light to find where the water is coming in, and then seal the leak. It could be entering via a door, a window, or a windshield gasket. Success to you.
Tom

Susan,
Why would you take a vehicle with an obvious drivability/engine problem to a transmission specialist? That’s like going to a brain specialist for a broken arm (just wondering about your logic here). I can’t give you a specific direction to solve the stalling problem. However, I would suggest that you leave the vehicle with a shop that specializes in engine drivability for a few days so they can drive it with a scanner hooked up to it, and the tech can monitor what’s going on when the problem occurs. This is the best course of action given the erratic nature of your Durango’s malady.
Tom

Glenn,
First off, there was no such thing as a “T-Bucket Roadster” 90 years ago. The base vehicle that the T-Bucket was made from had to be something that was not modified (whether it was a pickup or some sort of coupe or sedan). I just want to get a clear understanding of what we’re looking at before proceeding forward with advice. That said, when buying any car (custom, modified or OEM) conduct a stem to stern inspection of the key systems (electrical, drivetrain, powertrain, suspension, brakes, undercarriage, etc). In addition, the inspection might include an engine compression test, electrical values of the charging/starting system, hydraulic test of the trans (if automatic), fluid samples of drivetrain components such as diffferential/s, transfer case, transaxle, and any gearboxes in the drivetrain. I might even go as far as an engine oil analysis to determine internal engine health before making an offer. Finally, if the vehicle is touted to be an original rare piece, do a numbers match analysis to make sure it is indeed original. Consider bringing a vehicle appraiser in before the sale to confirm that the car is what the seller claims it to be. Best to you.
Tom

Martha,
Have the drivetrain control module scanned for codes. It sounds like the lockup converter control solenoid is not disengaging the clutch in the converter when you shift gears. This would account for stalling when you change gears. A good transmission shop should be able to scan it for you.

Dear Tom,
I drive a 98′ Honda Civic with 40K miles (automatic transmission). Lately the transmission seems to be amiss. Sometimes the car seems to downshift or lurch slightly. I told my husband about it and he asked me if the “check engine light” comes on, and I told him no. He said not to worry about it. However, I have a feeling that he is just too lazy to check it out himself. Should I be concerned? Also, my mom changes the oil every 3,000 miles on her car. Is it okay if we change it every 5,000 miles instead? Thanks for your help.
Deb from Little Rock, AR

Deb,
There is a TSB (Technical Service Bulletin) from Honda for this very condition on your transmission (bulletin # 00-012). Call your local Honda dealer and ask them what this TSB entails. As for the mileage recommendation, if you are using synthetic oil, then every 5000 miles is fine. If you are using conventional oil, then stick with every 3,000 miles. Good luck.
Tom

Jim,
Who told you this? The dealer? Your Uncle Charlie who used to work on cars back in the 60’s? Unless stated specifically in the warranty or owner’s manual, this is false. The Magnuson Moss Warranty Act of 1972 protects against this sort of thing. It states that the manufacturer carries the burden of proof of any failure whatsoever. They must prove that the installation of the aftermarket product caused the problem. If they can’t, then you are covered. Period. Get the facts straight before changing back. By the way, changing between synthetic and conventional oil does no harm to the engine. Success to you.
Tom

May,
The light is on because the drivetrain computer sees an anomaly in the system. Have the vehicle scanned for codes to identify the cause and repair it. The fact that the vehicle has a hard time rolling concerns me. It could be that the transfer case is locking up due to an electrical malady. Get it scanned and fixed before you do irreversible damage to the drivetrain. Best to you.
Tom

Mark,
Check the brake calipers to see if they are sticking. Also, check to see if there is a blocked rubber brake hose. Both of these conditions could cause the brakes to stay applied with your foot off the brake pedal, which would cause the rotors to heat up and warp. Rotor warpage causes run-out, resulting in pedal pulsation. Also check for worn inboard CV Joints, which could cause the pulsation as well.
Tom

Jean,
It sounds like there’s a problem with the gas tank vent valve, or the gas cap seal, or the evaporative emissions system. Go to the shop immediately after filling the vehicle when the light is on so that they can pull a code for diagnosis. Or you can schedule to leave the vehicle with the shop for a few days. Make sure the gas tank is low so they have to fill it. When the light comes on, they can scan for a code and track down the problem. Best to you.
Tom

Josh,
Check the emergency brake cable on the side that’s overheating. It sounds like the cable has seized, causing the brake to stay applied. Other conditions that cause brakes to hang up are worn return springs, loose anchor springs, and leaking wheel cylinders. Good luck.
Tom

If your car does fully overheat, get comfortable because you are probably going to be stuck wherever you are for at least 45 minutes. If you can’t afford waiting it out, that means calling a tow truck to get your car to the nearest repair shop.

However, an overheated car can do more then just inconvenience you with downtime or a potential tow, in the long run it can likely cost you a lot of money by contributing to wear and tear on your engine, radiators, pumps, hoses and even your vehicles head gasket.

The best thing to do in this case is to be prepared with an extended auto warranty. Not only will it help cover the cost of your engine’s repair but it will also pay for that tow to the shop – that way you can move forward with your day and you also won’t have to worry about why people are looking at you funny when you put that break and shake ice pack on the hood of your car.

“Deterioration in vehicle quality during the first three years of ownership—determined by comparing long-term dependability rates to initial quality problem rates—strongly affects overall customer satisfaction as well as customer willingness to recommend their vehicle model, according to the J.D. Power and Associates Vehicle Dependability Study SM released today.

The study, which measures problems experienced by original owners of 3-year-old (2005 model year) vehicles, finds that, on average, customers report experiencing 75 percent more problems in the third year of ownership than during the first 90 days. “

It’s no coincidence that most vehicles come with only 3 years of factory warranty coverage.

Where Does Your Car Rate?

Among the best – Lexus

Better than most – Acura, Buick, Honda, Lincoln, Mercury, Toyota

About average – Audi, BMW, Cadillac, Chevrolet, Chrysler, Dodge, Ford, GMC, Hyundai, Infiniti, Jaguar, Mazda, Mercedes, Mini, Mitsubishi, Nissan, Pontiac, Porsche, Saturn, Scion, Subaru, Volvo
