Default Leaking oil BB intake

OK, I have seen some of the threads on fixing oil leaking intake gaskets. On my 1968, 427 GM aluminum intake to an Iron oval port head I am using Fel-Pro 1212. Should I put some (small amount) high temperature sealers around all the ports???? The center open ports around the crossover exhaust heat tube is also filling with oil. Any ideas????

Hi

I used sealant only on all 4 water ports and both crossover walls. I also used the rubber seals, some don't and only use sealant there.

I don't think you need to use selant on the intake air ports.

Sounds good, make sure everything is clean and dry.

May also want to check to ensure all the mating surfaces are parallel...... so many of these old heads/intakes have been milled.

Hi

Not all intake bolts go htrough into the water jacket. I checked this up and only sealed the once that did, I think 4 each only.
