    Exhaust Gaskets (Again)

    OK guys - Don't want to keeping beating this dead horse, but I just got my new exhaust gaskets and I see people saying "make sure they're oriented right." They are symmetrical if you flip them over but they are not flat - if you look at them they all have a raised portion on one side and I was wondering if it mattered which way they go.

    Also, should I put a thin layer of 1211 on them even though they're new? Does the factory put anything on them?

    Thanks, Randy

    This is not beating a dead horse and a very good question.

    Raised portion faces manifold, no additional sealant needed.

    Ensure both surfaces are pristine - use MILD scotchbrite or phenolic scraper + solvent to remove all residue - make certain you do not remove any metal.

    Crush gasket evenly and torque.

    also the round one you will see a smal R on it when you install it have the R on the right bottom side so you can read it...............

    Are you saying the raised portion faces the exhaust manifold? I am talking about the head to manifold gasket. I used new gaskets, but I am unsure of orientation. I think I put the crush against the head. I had a major leak I am unsure which gasket was leaking. When I get more new ones I will be sealing with high temp silicone plus a new gasket. I fought a leak on my othe ski and now this one.

    That's correct. It is important to crush evenly and insure both surfaces do not have any left over gasket material and that you do not remove any metal from the head.

    I used new gaskets, but I am unsure of orientation. I think I put the crush against the head. I had a major leak I am unsure which gasket was leaking. When I get more new ones I will be sealing with high temp silicone plus a new gasket.

    If you do, go extremely light and work quickly...I suggest if you do add extra sealent that you look into a light film of permatex copper coat aerosol.
