    hello all, im at my wits end.maybe someone can shed some light.i have a rebuilt engine that i replaced the timing cover on because i could not get the oil pump to prime.now with the new cover i got the pump to prime and oil up thru the pushrods. but if the motor sits just a little while [a couple of hours]i have to start the process all over again, its like the oil is draining back to the pan? help please ,steve

    Does it have a Fram filter? That could be the cause of your troubles (no check valve)
