Does anyone else have this or has anyone else heard of it? The guy at the local jeep repair shop told me that most of the H.O.s have it. The thing is that I can start my XJ and rev it to hell and never get even a tick out of the motor... But put a load on er about 3000+rpms and it sounds like a diesel!!! If it were the bearings it would do it all the time right? He said that if you bought one new and took it in for this issue they would give you a 4yr 100K mile warranty or replace it and 9/10 times the new motor had it too... Is this correct?
