Air is much thinner than oil. Therefore aereated oil will pass to the filter much faster and greater quantites than oil without air. The idea is relieve the air BEFORE it gets to the rest of the engine.

As for it lowering the oil pressure then yes. But i offered the process as a test procedure. In fact, i have ran the Olds pump AND the filter feed as described above now fpr over 3 years with no problems. But, yes, it does drop the oil pressure to 30-35 psi. COLD HOT Hi-speed, Lowspeed doesn't seem to matter much. HOWEVER, i have OTHER mods to the engine oiling system of my car that opens it up to a lot more oil delivery so lower pressure in my case should be expected.

NOTE that BOTH of my oil pressure gauges (electric and mech) take readings from the FRONT of the engine.

edit: Actualy 3hree gauges. A mech gauge mounted directly at the filter too AND a shut off valve for the filter.
