Re: 2 piece rear main seal tips?
I have always installed them with the one side of the lip sticking up 1/4 inch. Slight dab of RTV on the block to main cap surface.
Follow gbic's help and rotate the seal. Also make sure the seal is installed with the sealing lips in the right direction:
His advice to use a little Rtv is correct too. Primarily it should be against where the maincap register meets the oil pan mating surface. If you examine the main cap you will see a machined 45 degree angle and that is what you are trying to seal. It the shiny line in the following pic and you only need to do it near the seal:
Disregard the bits of the old seal shown in the cap pic above.
