rear main seal ate up my crank
i've got a crank out of a 1 piece rear main 305 block & the rear main seal has ate two grooves in the rear of the crank where the seal rides. i was wondering how this is fixed? do they make a sleeve for it like they do balancers? do i have it welded & reground? do i trash it? it's a cast crank, but i still hate to just trash it.
