If you have a baffle in the valley tray, that is as good a place as any. The biggest problem I see people have is running more oil than the pan can hold. You should have drain backs into the block or pan from the heads, front and real. You should also have a good windage tray, not a screen to keep the crankshaft from dragging through the oil and causing crankcase pressure. How much oil are you getting in the puke tank and is it blowing out of the vent?
