I decided to buy the jeep I was talking about in my other post the one about if I should stay away from the 2.5.
I test drove the jeep yesterday and all was well. today I went and bought it and didn't drive it again utile after I bought it. Some one else test drove it after me and now today It has a bad nock. I don't think it was there before. any ways after it runs for a while it gets quieter. I took the belt off to eliminate any of the bolt on stuff and used a engine stethoscope and I think it might be coming from the rockers. It sound alot like a main bearing but doesn't seem to be coming from the bottom, more from the top end, at lest I hope. If it sits not running for a few minutes it gets loud when it starts up like the oil drains from the rockers and when it runs for a while it gets oil and runs somewhat quieter. can the rockers be adjusted or tighten?
