Author Topic: Intake gasket port leak (Read 4737 times)

Ok so I search with no luck in finding the answer... the first time I pulled off my intake I noticed the air ports on the blue felpro gaskets were black at the bottom, so I know the. Felpro gaskets aren't thick enough at the bottom of the port. Heads were milled a little to make the surface flat and free from improfections... maybe to up the comp a tid bit not much. So what are my options for intake gaskets to that will seal better. I looked at summit and saw some thicker gaskets, but they didn't have the crossover port open. Any opinions appreciated:) I'm in no rush

Did a machine shop do the milling ? Are you sure they are not milled just a hair too much ?

Yeah I'm sure. Its just the typical port leak at the bottom of the ports..

Sounds like to much was taken off.Felpro blue gaskets are not intended for aluminum intake manifolds because of leaks.

I do have a summit racing intake... So what kind of gasket would be suggested?

Felpro makes a thicker gasket for the aluminum intake,I think it is gray in color not that it makes a difference.

I haven't had much luck finding the part# for the intake gasket for aluminum intakes. Mine is a 350, any one know the part# to the correct gasket?

Hey I just read somewhere that you aren't supposed to use the end seals on the I take gaskets. Just the port gaskets and rtv the ends. I am looking at the same thing, just don't feel like taking my intake off right now-

Well all is good so far except the t stat housing cracked, so I ended up getting one with the o ring. I hear they leak, so I used some gray silicon to help. I also changed to a180° t stat. The surprising thing is the engine has gained 2in of vac when in idle and 1-1/2 in drive. Less pedal for accelleration aswell
