What is your favorite gasket material..

[SIR REAL ED]

What is your favorite gasket material to put between an intake manifold and the flat mating surface on the cylinder head?

Recommended thickness?

thanks in advance!

[DoubleGuzzi]

Cardboard (cereal box) soaked in oil, with excess wiped off.

High temp Permatex. Can be used on the exhaust side too.

:)   An Oreo box gasket has been holding engine oil inside my Norton Commando for almost 15 years now!

Proof positive that Digestives were, in fact, digestible....

Good point.

I've used that to hold many a copper o-ring in place during assembly.

Thanks.  My research says this is great stuff!

[MG_rider]

+1 for Hylomar Blue, good stuff!

[SemperVee]

If no gasket available -  PERMATEX RED made for things removable like exhaust pipes, etc. semi permanant.

[PeteS]

The problem with Hylomar is it almost permanent. You will need  heat and solvents to break the bond. Great for engine cases though.

I have had good luck using hanging file folders for gasket material. Its tough, and is coated with something that makes it very durable.  Ive had better luck with that than the paper gasket material they sell at the parts store

When I worked in the aircraft shop one of my duties was engine tear downs. When one came in with that permanent sealer I just a miserable time getting things apart. Then the cleaning was an absolute nightmare. My boss called it Yamabond. The customer paid more for his overhaul due to the increased hours. We used Permatex Ultra Copper on cases without gaskets and smeared a very light coat on gaskets. We overhauled radials, actually restored them. We even put thread on case surfaces as the manuals specified. Our engines were redone just as they left the factory right down to brass safety wire.

The green files?  Another reason not to through away all the stuff in my office.

Blue & sometimes mixed with alcohol.

I make a gasket for my still out of that stuff wrapped in teflon tape.

Flashbacks to my Eldo and little money/parts availability - valve cover gaskets cut from rubberized cork.

Those were the days ...
