Thread: Rear seal leak LS1

  1. #1

    Rear seal leak LS1

    Last winter I changed Rear seal at my LS1, but throughout the summer, the
    engine has lost 4 liters of oil.

    This winter I have used liquid gasket, which I have marked in red at my
    picture

    But now the oil leak has increased.

    Can anyone give me an explanation and a solution to my problem?

    Are you sure you have the seal installed facing the right direction? Also, be sure you put a little bead of silicone in the corner down by the oil pan. Always install the seal dry, its necessary to do that so that the seal burnishes to the crankshaft.

    Yes it is in the right direction

    The right direction is clearly not "This side out"
    Now I turned it and it looks more right
