1993 Jeep Wrangler Problems

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 spacer is used between the bell housing and engine that has a small slot in the 12 o'clock position. Filling this slot with RTV silicone and cleaning the seal area can help prevent damage to the seal.

Throttle Position Sensor May Fail

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.

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.
