Known Problems

An internal oil leak may develop from the intake manifold plenum gasket. The symptoms could include engine spark knock on acceleration and increased oil consumption. Our technicians tell us that replacing the plenum gasket should correct this issue.

Pinched or restricted transmission oil cooler lines can cause automatic transmission failure due to lack of lubrication. Our technicians recommend complete inspection of the transmission cooler and lines if this type of failure is noted.

Transmission fluid may leak from the area of the vehicle speed sensor. Replacement of the vehicle speed sensor and/or the speedometer adapter may be required to correct the leak.

The transmission may exhibit a delayed engagement after the vehicle has been parked for an extended period. This condition can be caused by transmission fluid draining back into the transmission from the torque converter. There is a drainback relief valve available which should be installed in the transmission oil cooler pressure line to correct this issue.

The manual transmission may become stuck in or blocked out of reverse or 5th gear. Our technicians tell us the repair involves replacing the transmission overdrive rail, lug shift fork, and synchronizer assembly with revised parts.

Excessive play cause by a bent anti-rotation bracket can cause difficulty shifting the transmission. Our technicians tell us that replacing the shift lever tower assembly may be necessary to correct this concern.

A clunk noise may be noted from the driveline when the transmission down shifts from 4th to 3rd gear. A revised overdirve piston and thrust plate spacer for the overdrive unit are available to correct this issue.

A delayed transmission upshift may be noted in cold weather (32 degrees F and below). Our technicians tell us that cast iron sealing rings for the hydraulic governor are available to replace the original teflon rings to address this concern.

Carbon buildup on the top of the piston is common. Over time this can lead to symptoms varying from light ticking to knocking noises. Performing a fuel injector cleaning procedure can often help the condition by removing some of the piston top deposits.

Oil leaks from the valve cover gaskets, timing cover gasket, distributor o-ring, and rear main seal area are common. The leak at the rear main seal area is generally not the seal itself but the bearing cap to the engine block seal. An oil leak could also be internal to the distributor, if oil is found inside the distributor then the distributor should be replaced.

Engine oil seepage may occur at the oil filter adapter plate. Our technicians recommend to check the adapter plate for warping and replace the plate as necessary.

The engine may exhibit excessively high oil pressure at cold start up. This may lead to distortion of the oil filter case. Inspect the oil filter case for any signs of distortion. If the case is distorted,  Connect an oil pressure gauge to the engine and start the engine while observing the readings. If the pressure reads above 80 psi, replace the oil pump.

The engine may develop an intermittent stalling or no start condition. Our technicians tell us a common repair to correct this condition is to replace the distributor pick-up plate.

The engine may develop a lack of power or stalling condition due to low fuel pressure. Our technicians tell us that this can be due to contaminates passing through the fuel pick-up screen resulting in fuel pump failure. If fuel pump failure occurs it is recommend to replace the entire fuel pump module as it includes both the primary and secondary fuel pump filters.

Erratic idle conditions which can include engine stalling may occur in warm to hot weather. Our technicians tell us that a new idle air control valve is available to correct these concerns.
