PCV drain back instead of catch can

[johnl]

I want to drain the PCV line back to the pan instead of using a catch can. Can I put a Tee in the turbo drain back hose for that purpose?

Boyd, here in SoCal has done it with a check valve in the drain back line.

The 1/2" line that I have now from the valve to the air box, drops down below both the air box and the PCV at the valve cover but it then goes back up to the air box. That is, there's a low spot in the line.

Im wondering about putting a Tee at that low spot in the line because from there it is still more downhill to a spot on the turbo drain back hose where I could put a second Tee to enable any oil in the PCV line to drain back to the sump.

Your comments would be appreciated, for instance, what about blow by from the sump, when the PCV valve is closed? Where does the pressure go in a stock engine when the PCV is closed by boost? If I install a drain back hose that's where the pressure would be relieved up to the air box
