Well this started out with a overheating problem and progressed into a what I thought was rings but the consensus seemed to be not scavaging oil from the block. Got my new Feuling pump the other day and tore out the old one. Low and behold I notice the cams aren't turning freely as they should. Seems at one point the bearings worked there way out and bent the keeper out far enough to rub the lobe on one cam. There was evidence of heat on the keeper. The bearings were back where they belonged when I got there. Evidence of bearing spining slightly on keeper but the cam plate looked good. Its a delkron cam plate. The bearings feel fine. How the hell can this happen? Can the cam set back into the inner bearing far enough for the outer bearing to move towards the crank? Anyone ever hear of such a thing? Suggestions? Everything seems OK but I can't bring myself to just reassemble it.
