Thanks Matt! I’ll give them a call tomorrow. Idk if the crank I picked up is any good so I’ll have to bring it to the machine shop to see if it’ll polish out. Don’t think it will tbh so I may have to hunt down another crank.Jenkins motor parts. https://www.facebook.com/pages/category/Automotive-Parts-Store/Jenkins-Motor-Parts-600911010048851/
I use 20W50 also and always have, VR-1 at that, so I'm going to say that oil wasn't the problem, I am more prone to think that there was damage done when your balance shaft bearing came out and you lost oil pressure, at least to some extent although there could be other contributing factors, the thrust bearing is not pressure lubricated, it only gets the runoff from that main bearing as it acts like a controlled oil leak dripping onto that thrust area. I am from the camp that believes that part if not a large part of the issue in the 2g was the goofy clutch master cylinder that could go out of adjustment and keep pressure on the thrust bearing, effectively wiping away any lubrication like a scraper. In a 1g though, you wouldn't have that same issue unless your using a 2g master. I also was suspicious that the 2g crankshafts were not properly hardened. You want your main bearing clearance to be looser than your rod bearings, especially the thrust bearing, so as to not starve the thrust.
