    ok, so i've got a pretty bad leak. i dropped the oil pan and did a new gasket w/ some rtv gasket maker and whatnot. didn't fix it. it's coming from the rear and front of the engine. anyone got any ideas on how to make a good seal? the only thing i can figure is maybe a rear main and perhaps where the crank comes thru the timing cover. anyone have any ideas? it pisses me off b/c i'm running amsoil and it's like pouring liquid gold on the ground. :mad:

    Rebuilt...it should have a new rear main and front oil seal right? Shouldn't be leaking from those at all. Did you replace the CDR dealie (top passenger side of motor, similar to a PVC for a gas engine.) Thinking you might be getting a bit of pressure in the crankcase forcing the oil out through the seals...

    Worth a shot, especially if the seals are new...and I'd have to assume you installed new seals.

    Are the seals the right size?
    Were they a tight fit?
    I was rebuilding a SBC350 once and had the wrong size seal and it leaked like a sieve, I replaced it with the right size and it was dry.
    Just a thought.
    :D
