MP valve covers knock out machined for pcv grommet (Chevy style)

that was one of the reasons I thought it would be better to counterbore the inside of the v. cover , to place the PCV higher in the v. cover & further away from oil slinging around, and futher away from the baffle. Perhaps, a better baffle design would help, too.
of course the PCV location is usually opposite the vent in the other cover: ie. if the vent is in the front left of engine, then the PCV should be right rear of engine.

Good thinking. My breather is exactly as you described....yet I still pick up oil.
