Gaskets
« on: November 25, 2024, 05:55:24 PM »
Hi all, back on my project and a couple more problems showed. Topped it off with fluids and the coolant started leaking from the intake seal so had to remove it . Bolted back on , fixed the leak but I guess I used the wrong intake gaskets? The exhaust crossover ports are just barely showing this it now has a exhaust leak there. What is the correct gaskets? Edelbrock Performer RPM intake with 6x #4 heads milled. Thanks for any information

It may not be the gaskets. There are two series of heads, pre-egr, eg. The intake manifolds and heads have the exhaust crossover ports in different locations. EGR heads are lower on the intake face and have an open space above them that are supposed to keep the oil on top of the head from caking up there due to heat. Earlier non EGR heads have a larger port that doesn't quite go up as far as the gap in the EGR heads. Early manifold on later heads will leak.

I have to assume it's the gaskets because it didn't leak before I took the intake off, idk I ordered a set from Butler Performance so we will see.
