Does Cork Make For Good Sealing Gaskets?

I'm sure you've seen how they perform,(don't perform), as valve cover and oil pan gaskets.
Why would you want to use cork as a intake gasket ?

Just to add...cork is marginal in places where it just has to contain lube splash and zero pressure (the oil pan and rocker cover gaskets discnik mentioned above).
In the intake you have a double battle of the intake passage vacuum (below atmospheric) and the positive pressure of the cooling system (above atmospheric) which the gasket has to resist.
Plus the dis-similar metals of iron and aluminum and the 45 degree geometry which adds a lot of extra creep which the gasket material must react to. The old cork gaskets I've removed were as brittle as a piece of mica...so I would not count flexibility as one of its strong suits.

Wantabe,
Please try to keep all of your questions related to a 3100 V6 VIN "M" concerning intake and head gaskets, etc. to one thread. By running multiple posts/threads on what amounts to the same issue(s) all you are doing is causing confusion and possible redundant replies. I see a total count of at least 8 very recent posts on overheating, head gaskets and intake gaskets. :nono:
