    its the front cover, i was thinking something like a cork gasket might compress enough and also fill in the divot, I guess I got a little too carried away cleaning the original gasket off, also for some reason with the new cover its jumping to 100 psi cold

    FWIW the thickest gasket that I know off is SCE 17100 is not cork. it is much better quality than a felpro...

    that brings up a timing cover gasket, my issue is the oil pump cover seal

    Im way over pressured at the moment, with the new pump cover it shot up to 100 psi at idle while cold. My reasoning was that a softer/thicker gasket would squash into that little dip thats causing my leak

    When I 1'st fired up my oil pump on the drill motor with the Vaseline in the pump.. the pressure was 85ish..... Fired up the motor breaking in the cam on the Joe Gibbs break in oil 1o-30 the pressure was pegging 120ish at first.... after a short amount of time it went to a more realistic 65 cold 35 hot idle..

    fixed the oil leak!, I lapped the housing to smooth out the mating surface because it had a divot that was leaking and made a thin cork gasket for it, and used new grade 8 hardware, it sealed and it idles 25 psi hot idle and I got the car on the road and its a totally different animal despite still having the high highway gears, it just pulls

    Do you know how thick it measures?
