1991 Jeep Comanche Problems

The head gasket may seep oil externally. An updated head gasket is available that should correct this concern.

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

The outer exhaust manifold studs can break and cause exhaust leaks, commonly noted as a ticking type noise. The outer studs, clamps, and nuts will need to be replaced and are now being tightened to a reduced torque value (20 Nm/180 in lbs).
