Not tryin to throw a hair in your biscuit.

Did you get "Your" crank back.

Is it truly "pitting" or has the crank been welded on. I have seen a few/bunch welded crank jounrals that have pitting on them.

I ground cranks for a "major" rebuilder for 7 1/2 years and yes we welded a bunch of them. The older 2pc rear seal cranks would eat up the thrust bearing surface and need to be welded and ground back to size.

BTW the older buick 231 V6 split pin cranks were the worst ones for eating up rod bearings and thrust bearings.

I alway mark my stuff before sending it to the shop so I know what i'm getting back.
