I replaced my intake manifold gasket like 6 months ago. When I was checking for boost leaks today, i noticed that it is leaking again right over the #2 cylinder where the back two bolts of the air horn go. Last time the gasket was completely blown out between the inside 1-2 bolts and the inside 2-3 bolts.

This time it is not blown out, it is just leaking. Should I go in there with some high temp red glue gasket maker and put a coat on both sides of the manifold gasket? It is a pain to change this gasket because of all the injector line clips and such that mount to the intake manifold plate.

Has anyone else had problems with the intake manifold gasket? I've been running just the HX35, I can't imagine the strain twin turbos could put on the gasket.

I found my gasket had blown out a few months ago. I replaced it and haven't had a prob since.

I must be unlucky or something. This gasket didn't last 6 months. At least my head gasket is still leak free!

haisley sells a upgraded gasket for this, haisleymachine.com. its under hp intake gaskets.

Hmm, I must have had mine off about 50 times and I've never had a leak . . .
And I run 70 psi sometimes . . .

Dumb luck maybe . . .

I looked at Haisley's site, it lists their intake manifold gasket as aluminum. Then in the description it says they recommend copper for off road trucks that get opened up/torn down frequently. Then it says they have a steel core high boost application gasket for even less money. I don't know what to think. I wonder if a metal gasket will even seal, those small bolts wont take much torque. Would I need to use gasket maker silicone to get a metal one to seal?

Try some Hylomar. It works well for me.

I got a stock felpro gasket and then used black RTV to seal it up any unevenness in the plate and manifold. Works fine to 40psi

That's what ^^^ I use the hylomar for-- only it doesn't cure up, so it doesn't glue your intake on and destroy the gasket when you want to take it apart.
