Problem Reports

Engine oil leaks from the valve cover gasket, oil pan gasket and timing cover gasket are common.

A ticking type noise may be noted from the engine area due to an exhaust manifold that has cracked where the pipes are welded; cracked manifolds should be replaced.

The throttle position sensor (TPS) may fail causing intermittent drivability problems like hard starting, stalling, and/or hesitation when accelerating. A failed TPS will require replacement, proper diagnoses should always be performed before replacing any parts.

Some models are susceptible to rear main oil seal failures in dirty or dusty conditions. As dirt and dust collect on the oil seal, the abrasion wears through the sealing surface. A rubber plug, installed above the starter, is being used in production that prevents the dust entry near the seal and extends the life of the seal. The plug is available from MOPAR and should be installed any time a rear main seal service is performed.

Jeep issued an emissions recall in late 2006 to update the powertrain control module (PCM) software on certain 1996 - 1998 vehicles. As part of the recall, the catalytic converter will also be inspected for damage and replaced as necessary. To see if your vehicle is included in the recall you can visit the Jeep website (owners' section) that allows owners to input their VIN number and check the recalls on their vehicle.
