Is there any way you can achieve a seal with the old case?
I have had trouble with the same seal (as well as the rear one behind the PTO clutch). The last time I put it in, I wrapped (plumber's) teflon tape around it and carefully seated it. So far, it has worked great. If the peening is not too bad, maybe you can clean it up with a rounded file and try the tape route?

IF the crankshaft isn't messed up where the seal runs, just a problem with the outside fit in block, then I would clean throughly and use JB Weld or Loc-tite, (Not the red kind) to hold the seal in. Sure as heck worth a try before buying an engine or block, mega bucks there.

ive tried everything nothing works time to cut your losses and go with what works thanks guys
As been mentioned, if the crank is good. Loktight either red or stud and bearing mount will keep it in the block and keep it from leaking, IF you get all of the oil off of the mating surfaces. I'd use the red and put it on both mating surfaces, then give it 24 hours to setup. JB weld will work too but there can't be any oil residue present for either one to work. Clean the block and seal surface with carb cleaner. I've used both with secess. Now if the block got cracked from pinging, that's another story.

My idea is blue Loc-tite will hold it and the red will make it much more difficult to remove when need arises. Neither will work if there is oil present, not going to be all that amount of pressure on it.
