"Proper" way to route the PCV hoses on SR20

[PandaProject]

So i have the stock setup on there right now which goes from the intake tube after the maf, to the valve cover T and then to the small "catch can" that comes stock on the back of the engine which then drains into the block.

I want to set it up so i dont have any chance of oil draining into the intake tube and going through the turbo. Could i just hook up an L style fitting which just runs one hose back to the stock "catch can" and then drains into the block? Or do i need to hook it up some other way? I see breathers on the intake end of the T but everyone says that is not what you should do.

Another option would be to run the hose that normally goes into the intake pipe to an aftermarket catch can and then back to the intake that way only air is transferred through the intake with a slim chance of oil passing.

Pictures would probably be better than explanations but either one will help!:naughty:

intake preturbo to catch can to block. should be no oil drainage use an ebay catch ca n rtv it and put in stainless dryer mesh to separate the fuel oil vapors. bigger the lines the less oil they move.

you would almost not need a restricting pcv valve because the preturbo will always be in vac. put a breather on the valve cover.
or route it to a non slash cut on the in.take
on blackberry sorry

If you can find a picture showing what you are talking about that would be very helpful Thanks for the info though! Everyone explains this different its super tough, BTW im Jacking this thread now.

you can ditch the factory catch deal, just run a hose from the vent to the head T. Then run the other end of the T to a catch can (greddy, ebay, anything) and the other port on the catch can to a preturbo vacuum. Just so you know the PCV is on the other side of the head. It closes during boost, where as this crankcase vent uses constitan vacuum to help scavenge oil from the turbo drain and can help reduce blow by.

Search before asking, its been discussed to hell and back in the tech section.

It helps to really understand the crank case system.

Think about it like this:
The piston makes pressure when it goes up right?... Well it also makes pressure coming down.
This pressure has to travel through the motor so it can be safely vented. Under higher RPM's the pressure is so great it can not vent quick enough. Suction is needed to assist the ventilation of crank case pressure.

What slip&slidin said.. valve cover-catch can-intake. this is how mine is done. the catch can is the same as the CS overflow tank, only made out of SS.
