I'm sure u did this, but I'll ask anyway. Is the seal retainer flush with the back of the block? Maybe there is a misalignment issue. Last one I did, I put the seal & retainer in with no crank & checked to see how the parting lines lined up.
Did this. No crank in block, seals in, everything was nice and round. Parting lines almost not detectable by finger. Did this twice actually. Thanks, J.Rob
When you put it in the block with no crank.. did you have the side seals in it.. I have seen where the retainer was cut shallow on one side.. it forces the retainer over... this was a after market retainer
No side seals were in, but I also fill the side channels with RightStuff when I install--so no side loading is present in this case. J.Rob
