I understand that......but some were saying the 15W/50 was like 50W when cold and it is NOT. Would you think straight 15W was too thick given his combo?......No and neither would anyone else and that is the SAE standard that 15W/50 oil MUST meet when cold. My point was that is wasn't the oil that caused the problem.

He said he had .002. Well how was that checked? With plasti-gauge or with mics. And if mics were used, was it only checked 90* from the parting line in a torqued rod, or in several places. The rod could have been out of round, or the crank pin had taper or wasn't round. .002 in one spot, doesn't mean it had .002 everywhere. I still think it was just tight for some reason. If you want to run em tight, that's fine, but it better be right everywhere
