Well finally got it torn down and found the culprit,almost missed it thinking it was the rear seal, was just going to pull the seal and replace it but decided to pull the cover for a look see.
Cover gasket had slipped out of position, amazing it held for as long as it did.
Thanks "duaneb55" for all the help.
