    If you think it's running the pan dry put restrictive push rods in it. That will keep oil to everything important and only restrict it at the top of the pushrod.

    If you go from idle to 5k and the pressure takes an instant dive it's probably not an air/oil issue..Air in the oil takes a little longer to cause a problem and the pressure drops a little slower and the recovery time takes more time.

    Like Poncho said...5 min or 5 seconds for drainback.

    Does oil temp change the amount of time it takes the pressure to drop? How hot is the oil getting? 140* oil flows way slower than 240*

    If your clearances are loose enough to require a H/V pump, what kind of pressure will you have with a stock pump?

    BTW..it's pressure not volume that pushes more oil to the top end...as long as the pump has the volume to make the pressure.

    Your shimmed bypass could be causing/contributing to the problem. 80 psi to the top end is a lot more volume than 60 psi.

    Maybe the oil pick up screen is to fine. A friend had a similar problem and changed the screen to one with bigger screen openings. That fixed his problem. Just sayin'. Good luck
