Niagara Gazette — TOM: I checked my ALLDATA database and there’s a TSB regarding this condition, apparently there’s a software update from GM on this. Take it to your dealer for this update, it should solve your problem. In addition, I suggest having the ABS computer scanned for codes and check the wheel speed sensors, and electrical plugs and wiring harness for cracked or broken insulation. All these faults could cause these symptoms. The TSB number from GM is Bulletin #: 09-05-25-001.
ELLIE FROM BURTONSVILLE, N.C.: I own a ‘98 Chevy Lumina with a V6 engine. There is a tapping noise when the engine is running. My tech said that it is a lifter problem and the engine should be replaced. Is there anything I can do that would be less expensive?
TOM: First run an oil pressure test with a mechanical gage and verify that the oil pressure is really low. If the oil pressure is up to specs, then identify which valve tappet is making noise and open up the valve cover/s to have a look at the valvetrain. This process will allow the tech to get a better grip on what’s happening with the valvetrain and what it will cost to fix. I wish you success.
CRAIG FROM CHICAGO: I own a ‘95 Ford F-150 with 282,000 miles and it runs well. However, the front and rear engine seals leak oil. If I replace them, will I cause additional problems?
TOM: Seal replacement could stop the leaks. However, if the crank journals are worn then the leak will continue. With this kind of mileage, I think you’re looking at a powerplant replacement. Have the crank journals, and rod & main bearings inspected along with the oil pump before proceeding with seal replacement (which would require removing the engine). It may be wise to just replace the engine with a rebuilt unit. I recommend the Jasper replacement engines. They come with the best warranties and are high quality remanufactured units. Of course, major repairs should not be done unless the rest of the truck is in good working order. Have it checked over before proceeding with powerplant replacement. Success to you!
