Can you take it apart to look at the seat and the check valve ? If not try some spray brake cleaner and compress air with the valve held open and then retest it with it close

Internal spring or no? A very light spring can help the valve seal. Is the valve itself plastic or metal?

ok i never seen a Vibrant valve, but you sure there isn't a "up"? i have a flapper around the shop that is a swinging flapper and if the hinge is not "up" it won't seal.

Joe Theres only a directional arrow on the valve and no matter which direction the flapper is, the same results. Leaks So now the question is, when you shut the car off, how much force is there going back to the pan from the lines. If I really blow hard and I mean hard, the valve will close but pressure has to be kept on the flapper.

Don't you have a loop above the entrance on the top line already? If so then that line should have some oil sitting between the fitting on the pump and the top of the loop, correct  I would install the anti drain back valve as close to the pickup as I could get it so it traps oil between it and the pump  I haven't had any troubles with the dual line Milidon oil systems not making oil pressure after sitting in a long time(5+ motors)

Oil line loop up top . Old Milodon oil pump setups never ever gave me trouble till I bought their new oi l pump and cover. It's a year old. I cant do anything about it yet till I pull the motor. So I have to try and see if I can get this to work till the mean time. Going to try the check valve like you said today.
