I made my own setup similar to the one from Danchuk.
I used the PCV valve from a late 70s 250 camaro. It already had the right angle adapter on the PCV valve, so I didn't need the tubing elbow.
PCV Valve side of engine Intake manifold side of engine. No apparent problem with it sucking the oil out of the crankcase.
BTW -
EMT = Electrical Metallic Tubing
NOS = New Original Stock
