anyone have pictures of a oil catch can setup on a rb25 with greddy intake mani? just wondering if i should eliminate my PCV valve or not? otherwise i think i should just run the catch can inbetween the exhaust side and the intake pipe.

i think thats right?

Why not just run the valve cover (intake side) vent to the valve cover (exhaust side) vent and then that to a catch can?

Or, if you have a system where the valve cover vents don't go back to the intake, you couls just run a can between the two covers.

[I have mine set up like my 1st suggestion I don't see why having a greddy manifold would change that...

Nah, as long as you have the catch can connected to the intake pipe, all of that is solved. Only thing that suffers is the emissions, but if you have done this swap, you obviously don't care
