Below does this catch can have a breather on top? and this good for a turbo setup?




This routing is a little simpler than the one above. The valve cover fitting has a breather filter on it. Air flows through the crankcase and out of the PCV port which now has a plastic 90* barbed fitting in it (no PCV valve). From the PCV port, the air flows into the side of the catch can and out of the top of the can. Air then flows back to the pre-turbo intake pipe. A 90* fitting is not required here because air flowing across the opening of the fitting in the intake pipe will draw air out in the direction of air flow (the same reason water comes out the top of a straw when it is submerged in a glass of water and you blow across the top of it).

This routing is not a closed circuit system with the only drive for the system being provided by vacuum.



Thanks to xenocron from G2IC for this PCV plumbing option.

 

No breather on top, this is a closed system as an open system would have a breather filter on the can itself. You could also run a line from the valve cover to the pre turbo intake instead of having a filter on your valve cover. Both work fine.

no. That can does have a filter on it. its not closed.

So your telling me that there is a fitting on top of the filter? If so than you are correct and makes that design useless. You want the pre turbo to create vacume and suck the crancase vapours out and with the filter on the can it will not. amkes zero sense.

 

Also, why would you want to recirculate raw fuel and shitty oil vapor back into your turbo?

I agree, on a boosted car the catch can should vent to atmosphere so as to keep all that junk out of the turbo

 

That's how the PCV setup is on a JRSC, and the crap that comes out of the crankcase gets all over everything and makes a mess. No way I'd run that back through a turbo. Plus you lose The "P" in PCV if you do it that way or with a breather filter. I've been using the Moroso setup and it works really well for boosted setups because the more you wind it up the more vacuum you get, plus all the crap is sent out your exhaust where hopefully it gets burned:
