Manifold Gasket Which Side Out

[glemon]

I have a very nice Payen head gasket set for my TR250, the manifold gasket is a nice composite with steel on one side and a composite material on the other, I see no markings on which side goes to the manifold and which to the block.

A web search on the general topic hasn't helped wither, this sounds like basic mechanic know how I guess I lack, what is the answer? I was thinking steel side to block as that is the more smooth surface, and the composite to the two manifolds?????

OK, I found one source that says metal side to the manifold, this was just a generic description, so much for my theory above, does that sound correct?

Did you find the answer to your question?

I found the following reference to an asbestos/steel manifold gasket for a Triumph Mayflower. Not sure if it's applicable to a TR250/TR6 though!

V.73G. / 2.11.51 / Engine manifold gasket

In view of a number of failures with Mayflower gasket, detail 43859, it has been found necessary to modify this packing.

A new gasket, detail 103978, has been introduced, which is made from a single thickness of asbestos with a steel plate interposition, as was previously used.

The new gasket should be used foe all replacements and such supplies of the former gasket, as are held, should be used up for replacements on the 8HP. Models, for which purposes they are completely satisfactory.

When fitting the new type of gasket, the steel surface should be placed towards the manifold.

:lol:

In fairness, the Mayflower's front suspension was the basis for the front suspension of the TR2 and subsequent TR models, so the two cars are practically twins! :wink:

It does match what he found at least (metal/steel side toward manifold)!

Hmmm unless he found the same page. :wink:
