    Question Rocker cover gasket installation

    Guys do you use any gasket sealer on your rocker cover gaskets?

    I'll have to remove my rocker covers after run in to adjust valve lash.
    So I'm thinking maybe sealer on the head side to hold gasket in place but not on rocker cover side?

    Cheers Dave

    If its the cork ones, (If the cork gaskets have the sticky backing I peel the sticky backing off the gasket and wipe with thinners til it stops being sticky.) I apply contact adhesive (the stuff in the tin can) to both the rocker cover and the back of the gasket, wait 3 minutes then gently stick it on.

    Dont put glue on the head, this is what I do and they stay on and never leak ...

    either cork (which i never use) or rubber gaskets.... glue them to the rocker cover
    I use superglue for the rubber ones (ppl know use contact cement for the cork ones)

    and a wipe of Hylomar on the other (head) side of the rubber gasket ..and let that go 'off'
    and it will never leak and is easily removable

    There a thick paper type material not rubber and not cork. They where in a Felpro gasket kit I bought.
    Should I buy differant ones?

    glued to the head. the rubber gaskets have a sort of c section on them than sits over the edge of the head but they arent a perfect fit so i always put a couple of drops of super glue under the corners/curved edges to hold it in place as they can be a bit tricky then the roccer covers can go on bare so any time the roccer covers come off the gasket stays on the head.

    hope that makes sence!

    never tried it but it would work the same i would think. i only used a couple of drops to hold it in place on the head never glued the entire gasket on.

    Definetely use the rubber style gasket. They're acl brand and repco sell em. The bottom of the gaskets have tabs which locate them to the cylinder head. You can use a little contact adhesive on the bottom of the gasket to simply hold them in place. No sealant is required between the rocker covers and gasket. There are sealing grooves in the top of the gasket. As long as your covers are in good knick there should be no leaks.
