1992 Cherokee inline 6 4.0L
150,000 miles.
Sounds like a motor/tranny mount but its not, only bangs in neutral, and at idle. Bangs seemingly randomly (not rhymithly like might be associated with a connecting rod bearing) Bangs a few times when I start it, and at idle once its warmed up. I've got 40lbs of oil pressure at idle. I can also get it to make a single bang if I move the throttle fast off idle in neutral. Same noise everyone thought was motor/tranny mounts on the last billy mtn trip. If you put your hand on the oil pan you can feel the banging/rattling as if its inside somewhere not in the mounts, which I have checked or replaced depending on condition. Noise is more frequent when running the winch at idle, or using power steering etc that puts slight drag on the engine.
Any ideas or suggestions?
