My work on cleaning up the crank for my R5Alpine engine rebuild came to an abrupt halt when I noted this defect on the the No 1 big end journal. Is this a deal breaker? ie I'm not keen on doing a regrind - would rather find a crank in better condition to start with. To me, it looks like a fault when the engine was last/first built, not acquired during use.
I've also attached photos of the bearing shells - all showing significant wear and fatigue and some crap that went around in the oil - but to me, none look like a bearing "fail" and I am curious if you can pick the shell that was on the journal with the defect (they are not in order!)
