You might want to be very careful with the PCV valve as it is plastic and I don't think they are available anymore??? There is a ring on the inside of the vent box that holds it on and it is easily unscrewed with needle nose pliers. I clean ours with electronics cleaner so the plastic won't get damaged and someday I'll have to make a replacement from moderm materials. Does your car ever backfire? If so that means pressure is getting into the plenum and that could be getting the oil into the MPC.
