Default Re: Rear Block Babbitt

So, here is my issue.
I have had a very bad leak at the rear. Thought at first the pan gasket but no. Then moved on to the rear seal. Picture shows the old and new rear seal. Removed the old and that is what the top looks like compared to the new.
Installed the new torqued to 80ft lbs and the crank locked up. Same shims as before.
Have now pulled the crank expecting to find some particles/debris at the top of the block seal cavity but found nothing.
It appears the crank end is jammed against the seal itself (second picture). You can see the shine (red area) left by just the few turns of the crank after loosening the bolts.
I realize any new part is never an original so I'm going to assume you need to file this area to stop this from happening?
