| If you don't have restrictors in the heads, and you are using a high vol oil pump, the small amount of blowby that is in every normal engine can push the abnormally high oil in the heads out the vents. This is an easy fix with the engine in the car, although time consuming because of the valve train readjustment (solid lifters especially). Drop a inch long piece of aluminum or steel rod down the oil supply galleries below the rocker stands which supplies oil to the heads. If it's a tight fit, drill a 0.090" hole through the rod...if it's a loose fit, don't bother with a hole...enough oil will flow around the dowel. Secondly...make absolutely sure you have a PCV system connected and functioning correctly, as this will relieve the small amount of blowby by adding negative pressure to the crankcase. Best of luck.
