how to seal intake manifold
i've installed intakes w/ and w/o the end cork gaskets.
both methods work ok but can develop a small leak at block/head corner over time.
what is your favorite method to seal intake manifold?

last time i installed timing cover i used the short cork gasket on the oil pan w/ RTV; it didn't leak.
i'm tempted to install intake w/ all gaskets and all rtv to see how it holds up.
i have never tried all rtv on all intake manifold gaskets b4.

Coating the cork (or rubber) end gaskets with RTV will make them slide like a well lubricated bearing pad. I use the end gaskets, a dab of "Ultra-Blue" in the corners and a thin coat of Loc-tite #518 top and bottom of the gaskets. the 518 will cure very quickly as soon as there is no air near it - the exact opposite of RTV. The "Ultra-Blue" is more oil resistent than standard RTVs and will maintain a seal longer. The 518, if given 30 seconds to cure, will not let the end gaskets slide around. I also use 518 around the water and port openings (.010" film) just to give extra protection against leaks.
You should always have clean and slightly roughened surfaces whan using gaskets.
