View Full Version : Use exhaust manifold gasket, or not?

Hey guys. Took my exhaust manifolds off to repaint them and to replace my valve covers. It's time for them to go back on.

I have manifold gaskets that I got from skidim just-in-case but it seems like most here don't use them (indeed, even Indmar doesn't).

So what would you do?

- Use only the gaskets?
- Use the gaskets w/copper RTV?
- Use only copper RTV?

I would use the gaskets dry, torque the manifold bolts with a torque wrench.

Make sure you have no paint on the gasket surfaces of the manifolds.

I'm no expert, just my opinion

^ x2 ........

Indmar doesn't use gaskets because when its new its free of defect and perfectly flat...my manufacturer does the same thing on various components but they state when repair is needed use a gasket...

^X3 Also a good idea to use new bolts with a little anti-seize, and run a tap and clean out the hole with compressed air. Don't need the new bolts for anything other than to make removal easier.
