Thread: FE Intake Oil Leak -- End Gaskets or Not?

Tweet

Thanks John. I'll definitely get another set of hands to help me.

By the way, I called Edelbrock today. After being on hold for 30 minutes I spoke with a technician. He said the reason they recommend not using the gasket is that the cork gasket tends to slide out from under the manifold over time. He said installation is tricky but even if you get it right, the cork gasket slides out from under the manifold over many duty cycles. I told him that a 1/4" bead risks air pockets like mine experienced that failed very quickly. He acknowledged that was a risk and said it is my choice. I asked him if there was a measurement for the gap where a gasket is more or less desirable. (The compressed RTV from my previous install measured at 3/32). He said there was no range where they would change their recommendation but the larger the gap, the less desirable RTV is for the install. (Somewhat contradicting himself). He did say the Right Stuff is a great substitute for the RTV.

Hopefully this helps others avoid a re-do. Thanks again!
