Hey where can i get .040 or .030 main berrings for my motor its a 1991 b18a1. i bought it with a knock pulled it apart and its got a knife edged crank so i had it turned. now i need those berrings or get my crank welded so any help
You don't ever want to get your crank welded being that it will have to be re-balanced in that case get a replacement crankshaft and micro polish it. Go with ACL bearings or ACL race bearings depending on your build.
