Quote: Had the same problem sometime ago. Staggered the seals and never had a problem again. Chuck
Also,,I silicone behind/back of the seal and put a little on the ends where they meet together in the housings. The oil you are seeing may be going BEHIND the seal and the seal to crank area not be the actual source of the leak.
I think my problem was the rubber oil pan seal. Here is a pucture of how I installed the main seal.
I'm not a fan of rotating the seal... as you see in the pic you cut the wings off... thats just another point for a leak... I put a smear of silicone across the joint and the wings... I've never had a true main seal leak but have had a pan gasket leak... alot of us think its a main seal when really it isnt... JMO
