Oil catch can install

[opfor2]

I just received my "Evil Energy" oil catch can off of Amazon. How do you tap into the PCV system on our Tahoe's?

That seems to only put the catch can in line with the driver side PCV system but doesn't address the passenger side, why is that?

Passenger side is clean filtered incoming air, driverside is dirty out going air. Youtube is your friend (how crankcase ventilation works).

Can you confirm for me which of the intake manifold fittings is the IN and which is the OUT?

 

[donjetman]

clean air goes in the passenger side
dirty air comes out the driver side

I don't believe that is the way it works on the newer 2015+ generation. Of course now I just realized - this is in the appropriate forum, and I am not!
