1991 Jeep Comanche Problems

Engine Oil Leaks From Valve Cover, Oil Pan, and Timing Cover Gaskets

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

Ignition wires may fail and cause engine performance problems

Ignition wire failures can cause a rough idle or intermittent engine misfire and there might not be a Check Engine light.

Dusty conditions may cause the rear main oil seal to leak
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.
