I was thinking about putting together an isolated PCV system and then a catch can to better collect the oil droplets coming from the crankcase. My reason for doing this, is that it seems with the current PCV set-up the oil droplets are immediately introduced into the UIM.
I know there is a PCV tube or pipe that snaps into the UIM gasket (internal routing). And there is also a vacuum tube which sits on top of the UIM manifold which leads to the intake piping just before throttle body (external routing).
What I want to do is somehow link this piping together so that the PCV gases are directly routed to and through the catch can. My desire is to remove more of the oil that is ending up in the intake eventually pooling in the LIM.
It looks like there are 2 options, to route the internal PCV piping directly to the external vacuum tube on top of the UIM OR to drill a hole in the PCV intake housing so I could route the PCV gases/piping externally, out and around to the vacuum tube. I would cap the top outlet (vaccum tube) of the UIM and run piping from the PCV housing to the intake piping just before the throttle body.
If all of this makes sense, I wanted to get opinions on here, especially if in doing any of this I'd screw up the MAP sensor readings or operation.
