Thread: Manifold gaskets - Use compound or not?

If the flange faces are in good condition, i.e. flat, there should be little need for jointing compound. Shallow irregularities can be treated with Maniseal or similar but really it is a good idea to machine, sand, or file them flat,

As above. No need for any compound provided the surfaces are in good condition, and preferably fix them if necessary. Note that particularly for the manifold to head join, there will be a small amount of movement on this joint every time the engine heats up and cools. The same will apply to a much lesser extent to the join between the manifolds.

In, done, running...well!

**** of a job though!
The outer bolts for the inlet manifold are awful to get to, long extension bar out past the wheel was the only was to get to the one closest to the firewall.
I think id take the whole head of next time, be a lot quicker!
