    Hey k5ers,
    Just curious what your procedure is for applying new oil pan gaskets for older k5s with the 2 rubber gaskets at each end of the pan
    1) Do you apply rubber gaskets 1st and then apply cork gasket to the block then bolt oil pan on?
    2) Do you apply the cork gaskets 1st to the block and then the rubber gaskets then bolt oil pan on?
    3) Do you apply the rubber gasket to block and apply cork gasket to oil pan then bolt on?
    I did step 3 applied gasket to the oil pan then bolted oil pan on the block and the gasket just doesn't look like sealed with rubber gaskets.
    I'm thinking I should of did step 2)Applied the cork gasket to the block, then the rubber gaskets, then throw a bead of rtv sealent on the pan then bolt pan on.
    Changed many gaskets never oil pan gasket and just can't figure out the best sealing method where the rubber gaskets meet the cork gaskets

    I ran into the same dilemma, and I kept getting leaks.[​IMG] I talked to the guys at the local speed shop here and they recommended a one peice pan gasket. Moroso I think (sorry its been awhile.) Man was it slick! Easy to install, new bolts, and no leaks or futzing around trying to get it all lined up properly. The only drawback is that it costs about $25.00 which is kinda pricey for a pan gasket.

    Put a dab of rtv at each point were the seal meets the cork and a thin bead of rtv on engine block side of gasket. H ave done this several times, no leaks, P.S. just don't use too much rtv, just a thin bead. put seals in first.
