Oil on the back of the block?

cork and rubber gaskets are NOT worth the trouble IMO. it's pretty much hit or miss with them. if you have a good method that works with them then great. but I'm sure that for every one person that has success 5 or 6 others don't.

I also dimple the lower intake at the rear and at the front but I run a thick bead of silicone and have never had an issue.

A lot of Fel-Pro 302 intake gaskets now have rubber end seals now with lips on each side that keep them from squeezing out. I've used them on my 90 with no problems, but on the 351w in my 68 they all seem to still come with cork end seals, which I throw in the trash and use silicone instead also with no problems.

I've had a PCV valve drip oil out back before because it was never changed. A lot of guys don't even know where they are.

valve cover/intake gaskets.

valve cover/intake gaskets.

Intake is clean, valve cover and heads are clean.

I'm thinking it was oil coming from the flywheel bolts without thread sealant.

The outside of the Bell housing is clean too.
