I lost the photo leading up to this, but basically it's mounted and ready to go just behind the AC compressor. Inside are a couple of brass wool pads. A -10AN fitting on the bottom will connect to the crankcase. The connected hose leads to the oil cap, with a check valve to keep air flowing towards the cap only. The 1/4" fitting will connect to the PCV valve. Normal driving, check valve stays closed and PCV draws from the crankcase. Oil cap & passenger side AN fitting will connect to filtered intake air as a "fresh air source". Under boost, PCV closes and blowby is drawn into intake. If pressure warrants, check valve will open and allow some passthrough from the crankcase into the oil cap and on to the intake.
