Known Problems
The alternator belt may develop a chirping or snapping noise over time due to pulley misalignment. There is a revised alternator bracket to address this concern. If there is still an issue after the bracket has been replaced washers can be used to align the alternator pulley.
Oil leaks may develop from the valve cover gaskets, cam plugs, camshaft seals, front crankshaft seal, and the oil filler bracket.
A squeaking noise from the exhaust may be caused by a worn sealing ring between the exhaust manifold and the exhaust pipe.

Fuel pump failures are not uncommon on higher mileage cars. Our technicians recommend to replace the fuel filter if the fuel pump is being replaced.

It is not unusual for engine vacuum hoses or sensor electrical connectors to cause driveability concerns and/or the Check Engine Light to illuminate.

An intermittent stalling or no start condition may be caused buy a failure with the distributor pickup plate.

Various driveability concerns can be caused by deposits on the back of the intake valves. Fuel injector cleaner has shown reasonable results cleaning light deposits.

A hesitation on acceleration may be caused by a plugged EGR valve back pressure tube. EGR valve replacement is not generaly required.

A dirty throttle body can cause a low idle condition resulting in a stalling condition.

A hissing noise from the exhaust may be caused by a poor seal between the exhaust manifold and the catalytic converter.

Some engines may experience a cold engine knock that lasts for three to five minutes after start-up, which is often misdiagnosed as a valve lifter noise. This noise is commonly not an indication of a failure and should not be a reliability or durability concern.

Excessive oil consumption—defined as more than one quart per 1,000 miles (on vehicles with less than 50,000 miles) or more than one quart per 750 miles (on vehicles with more than 50,000 miles)—is common. Replacing the valve guides with an updated version should fix the problem.

A broken rear torsion bar can cause an abnormal noise over bumps. The torsion bar is part of the rear trailing arm, which must be replaced to correct this issue.

The retainers on the horizontal wood door trim tend to break after repeated door slamming. Our technicians tell us that the trim can be secured by using silicone adhesive.
It is recommend to change the engine oil and adjust it to the proper level and run the engine to bleed any trapped air from the valve lash adjusters before testing for excessive bleed down.
