Just to classify. I got confused.

Canadian 4 bolt mains did not all come with anodized caps.

A "hecho in mexico" crate engine had brass mains. Or maybe I am confused.

I hate talking out of my arse, clearance for those was the skin off my teeth.

Main to journal oil pressure could not keep up.

So, since I don't understand, every crate engine I rebuilt from "hecho" failed at the same point.

Sometimes just bleeding on the feeler gauge would account for clearance.

A canadian 4 bolt should and will develop. But if you sneeze and cheap out, that journal just welded itself to the crank. No coming back from that.

A 1/4 mile and a seized engine, will jam and make sure you have a head brace.
