Doing that, without any check-valves, is a terrible idea since you'll be pressurizing the catch-can AND crankcase during on-boost conditions!

There's no pressure in there, only vaccum. I have the 3rd tube going to the intake pipe, before the turbo with an inline filter.

How is there no pressure when you have a line run directly from the intake manifold?

I meant to say he did it wrong, that line gets ran to the VC. I keep thinking DSM's where the pcv valve goes to the vc. Obviously that won't work hooked up to the intake manifold.

Evos and DSMs have their VC breathers and PCV valves setup in the same way, just in different locations.

If you want to route both the breather and PCV to a can then yes, you need 2. If you do just one can though then pick which of the above two is more important to you and go that route. I personally have 1 can setup between the VC breather and intake pipe.

Do you have a pic of it under your hood?

Why not have both the VC outlets go into the intake pipe? The PCV going into the intake mani is pressurized under boost so it does nothing. If they both go into the intake pipe the turbo will be sucking air out from both VC locations at all times. Granted this will probably look messier, but oh well.

And all that blow by going into the turbo? no thanks.

The 2 red hoses go to my catch can. Then the green hose goes to my intake tube. No pressure, only vacuum.

Thats the point of a catch can dude, to catch the shit and suck out vapors. It's a better way of doing the same thing the factory did in my opinion.

This. Just run both VC vents into a single catch can and then to the intake pipe.
