it vents to the atmos via a breather filter, you will probably find you will need to T in the crank breather and block off the PCV valve before you get anything in the tank mind

in simplistic terms:
there are 3 breathers to an ej20.
The 2 cam breathers, 1 each side on top of the rocker cover.
The 1 crank breather, to the right as you look at the turbo head on.
All 3 need to vent to the catch can, but you need a vent from the catch can to allow the pressure to disperse.
So in effect you need 4 outlets to the catch can, oh and a drain point at the bottom is also bloody handy.
Catch can should ideally be about 1.5 or 2 litres

As above if you only connect rocker cover side then it won't blow by the gases meaning the catch can will just look pretty and not function. The idea is to "catch" the dirty oil and return the clean air. Peanuts has it in one

and secondly you advise of a 1.5 or 2 litre tank, why is this? how much oil should it be catching?
im a little confised.

Iv been reading this thread with great interest, you say you need a catch tank with 4 outlets, will this be a custom jobby? or can you just use a "T" peice as most tanks only have 2 outlets....

I fitted my oil catch can where the original EVAP canister used to be. I also had 3 ports on the tank, one to rocker cover breathers, one to crank-case breather, and then one to atmosphere with no filter. Really easy to install mate. Give me a pm if you struggle.

I thought you were meant to retain the PCV valve and block off the vent into the inlet manifold leaving the PCV to vent directly to the catch can?
If you only vent the cam cover breathers to the catch can you'll hardly catch any oil.....if any???

Is there any adverse problems in blocking off the PCV?
Has anyone got a nice little drawing for nuggest head here, who is struggling to figure out what hose to cut into and join up?
I've got a three outlet can, one venting and two for connections somewhere?
