2JZ swapped s14 oil catch can - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

Whats up guys!!

So I'm swapping the 2jz vvti into my 240sx s14. I am going single turbo and AEM Infinity 6.

Regarding oil catch can..

I know the two styles of catch cans. 1 is a breather and 2 is closed loop back into the intake manifold. I'm leaning towards the closed loop so I dont get oil/fuel fumes into the cabin. (I will be driving this car A LOT)

My question:
How do you guys run the catch can systems with these swaps? Should I use two catch cans? One for each pcv on each valve cover? One catch can with a T for both pcv?
Also, I believe theres only one port large enough on the intake manifold so if i do run two catch cans where do I connect both to vent?

Thanks guys!

on my 1jz vvti I ran the exhaust side valve cover vent, welded a -10 AN to it, to a mishimoto catch can and to the intake pipe. simple and works great. I have the stock PVC on the intake valve cover to the intake. and the hose connecting both valve covers
