Turbo PCV setup help
You guys with turbos: how is your PCV system set up? Factory or aftermarket can respond. I've been reading a lot on the subject, but I want to get more first hand experience folks chiming in. I'm tossing around the idea of simply changing my PCV valve to a forced induction friendly one and changing nothing else. That sounds a lot cheaper/easier than a catch can setup. I won't just vent it into the atmosphere.. I want to make sure there's a proper vacuum to help the funky gas and moisture to escape from the crank case. I have a 2006 Focus zx5 that will get a turbo this summer. I guess I should put that in my sig.

delete it.. breather on valve cover i've had mine that way for 20k miles.. still squeeky clean inside.

Mazda makes a PCV valve (used on the Mazdaspeed Protege) that will work, or just delete it. I like the breather better...

Why delete the pcv system? I believe the point isn't just emissions control, but to remove moisture and possible unburned fuel from blow by.

Under boost, the engine will suck a shit load of oil into the intake tract via the PCV line. Unless the proper style PCV valve is used (like the one mentioned above and also the 03-04 Cobra PCV (though not the best one)), or an oil-separator is used. If you can run a breather and can deal with occasional oil smell, then just do that.

It's only going to suck in a load of oil if I keep the PCV connected to the intake manifold with the stock PCV valve. If I move that connection to the ambient side of the turbo (vacuum, not boost) and use an oil catch can this should be equivalent to a stock setup. OR just use a boost-friendly PCV valve and leave it connected to the intake manifold, which I want to do since it would be far cheaper and not require the catch can. As for running a breather on both valve cover IN and crankcase OUT it doesn't seem like this would accomplish the task of properly releasing the gases/moisture.
