On rocker cover breathers there are two outlets each side.
Block the bigger ones off and the outlet where they lead to, and route the two smaller ones into the catch tank.
Under the intercooler, by the turbo there is the crank case breather. This has a t-piece, one end goes into the intake pipe and the other end into the throttle body. When the car is on boost it vents to the intake pipe and when off boost it vents to the throttle body. Take the t-piece out and block the hole in intake pipe and also the throttle body. Take a hose from the crank case breather to the catch can.

That's all 3 inlets sorted for the catch can and you can do what ever you want with the outlet.

Hope that makes sense.

How does it know when it's on boost to blow into the intake ?
Is there some sort of valve that only opens when under more pressure.

There is a pressure vacuum valve fitted below the throttle body that closes when on boost.

PVC valve ? it allows the air from the breathers to route into the engine when the engine is drawing in vacuum on NA cars i believe or it could be the other way, its usually piped from the block breather and t'ed off and one side to the air box and the other to the inlet manifold with the use of a one way valve called a PCV valve ( cant remember what it means right now as its 10pm)



thats under the thottle on a V3 sti,,,, and to be blocked off when fitting a after market breather

I saw in some 'how to guides' that people were removing that valve and replacing it with a blanking plug. When I fitted my catch tank I just cut the hose attached to that valve and blanked the end off. Seemed easier than trying to get that valve out as its in a pig of a position.

this is why i was advised not to fit a return to sump pipe as if the car is not used regularly you will end up returning water to the sump.

Has anyone installed one of mad hammers catch cans yet I'm looking to do this at the weekend

But need the hoses

Believe they are 10mm and 15mm

With regards to the avcs can I just plug 1 off each side and route the remaining two

Also mad hammers catch can has 3 inlets and a main breather ?

The main breather is the outlet, route it somewhere under the car.
