The oiling issue was because with the cap pushed off it seat the crush on the bearing shells was not there any more and the main bearing shell rotated just enough to close off oiling to the journal and up to the rod journal and caused a rod failure. If the studs would have been strong enough to keep the main caps in place none of that would have happened. Root cause was main studs did not hold caps down tight and allowed other things to happen because of that. The witness marks on the caps says it all, they were doing that for a bit before things progressed to failure. They were ok at 1000 and 1300 to the tire but did not like 1500 to the tire. The purpose of this thread was to point out the weakness of this engine that lead to failure was main studs due to material type were not up to the power level being made.
