exhaust gasket question 200

That gasket doesn't require sealant. The important thing is to tighten the 3 nuts evenly, so that the gasket seats and crushes properly. Use anti-sieze on the studs. I don't use a torque wrench, but I have found that tightening those nuts as much as possible by hand with a 6-inch ratchet is enough.

Also: if your previous gasket was leaking for any significant amount of time, it is possible that the leaking exhaust has etched a piece of the manifold or the pipe, and the mating surfaces may no longer be flat. If this is the case, you will need to have this issue fixed or else no gasket or any amount of sealant will ever work.
