Hi All, I am changing over my Exhaust Manifolds as the old ones were frost damaged. I have the new manifolds and new gaskets, Do I need to apply any kind of sealant to the gaskets before I fit the manifolds or place them where the old ones were and fit manifolds. All replies appreciated in advance
Abe.

Just replaced my riser gaskets last year. The machined areas on the manifold and elbow (flat areas the gasket seals) looked to be in good condition on my engine. So, I just put a thin coating of Aviation Form-A-Gasket on both pieces and re-assembled everything.

If those machined areas are rusted heavily and not smooth anymore there is a possibility the new gasket won't seal as well as it should. Not to worry cuz that can be fixed by any machine shop. It just requires a little more work on your part...
