Rod bearings 'hammer', mine is definitly a valve knock. As far as #4 valves, my findings are the #4 exhaust valve has clearance no matter what stoke it is as long as it's #1 TDC 0 deg. I think it may even have clearance on #6 TDC mark O deg. -----Dani B. #5003 --- In dmcnews@xxxxxxxxxxxxxxx, mike.griese@xxxx wrote: > Have you checked your bottom end bearings?
