Would the amount of pressure necessary to push the oil back up thru the oil separating device be less than the pressure necessary to activate the shut off valve?

I believe there is a check valve at the nipple of the oil pan connection that will prevent oil from going up the tube.
I doubt a blocked PCV would generate enough pressure to blow 7Q oil past a check valve, *not* blow a seal/gasket, not put pressure on the shut-off diaphram, and have normal performance. Something is very odd here. Did you check the coolant for any signs of oil in it? Did you do anything to the oil cooler lines?
