Can I ask why? The lack of forced induction removes any need for them?
MY00 Red RX, a nice daily that was sold off once the B4 became reliable...
MY02 Blue B4, aka 'The Project' - v8 JDM STi engine package and assorted other 'goodies' - Sold, then bought back for parts. Stripped and crushed.
MY03 Blue RX, the newer old daily, pretty well more B4 than RX now... In the process of being converted to the track toy... Watch this space!
MY02 Silver Wagon, H6 conversion, full blue/black leather and almost full black interior to go with it.
MY03 White/Silver H6 Outback, donor car for silver waghoon.
MY97 Silver RX, acquired to become track car, but plans changed. To be stripped and scrapped in time.

Those catch cans are shit too without modding them.. You have to make a baffle and install some filtering material for them to do anything at all....on a turbo motor.

can i suggest just doing an UEC once every 3 months instead...
if you must... Both vents from valve covers need to join and go into the inlet.. then the outlet needs to go back to the intake pipe (post filter) either side of the intake plenum (the black plastic interfooler box that connects to the Throttle body) has a joiing pipe clipped to the bottom.. where this connect to the intake piping is where it needs to feed back..

The directions are for N/A 
Pretty crap pic, but The black thing with an outlet to the right of the oil filler is the breather from the valve cover, same on boths sides.

Sighs. .
It's an ej25 Double overhead cam engine Yes?
The Big black box that says Subaru on it. . Fits directly to the throttle body. ..
Underneath that thing. ...
A hose. .
That goes to where they need to go.

Sounds awesome mate! I need to do one as well, I'm attempting to install a breather can. And then after that maybe an oil catch can.

it lowers the amount of oil that gets into your intake e.g. intercooler and throttle body
