Well, I'm new to this and to be honest, I didn't even think about a turbo PCV setup being any different. Well I finally got my car together and drove it around. Of course on the initial start up there was tones of smoke from the header wrap. After that subsided I went for a drive. At a light there was smoke coming out, so I pulled over. Long story short, theres oil coming out of the breathers that misted in the engine bay.

So is everyone running a line from the driver side to the passenger side and running a catch can or what? Before the turbo there was no oil to be seen in the engine bay.

Did you cap all the intake side ports?

Did you cap the valve covers and just running a breather?

Capped them all and running a breather on both valve covers

I capped intake mani, ran 3 breathers total. 1 on oil cap, and 2 on back side of motor.
I get a little misting but not to bad at all. Much better then it was without breathers.

You can do what I did and cap the intake manifold.

Run a hose from each valve cover to a catch can without a breather. Then run a hose from the catch can to the intake side of the turbo.

Then install a breather on the oil cap.

So you have the ability for the engine to breathe, and also you get some vacuum getting pulled from the crankcase when under boost.

Its pretty bad compared to before the turbo. Before the turbo you couldn't see any misting. There is actual droplets all over near the breathers. Anyone run a catchcan setup with sucess?

Any pictures? sounds like a good idea

Im just running breathers on both valve covers hoping that will work. I made a catch can but im outta room for it. lol

Hopefully you don't have the issue I'm having

You need two catch cans and a one-way check valve in the PCV line.

See this thread:

With the proper PCV configuration you don't need any breathers. Are you running an LS6 valley cover?

No ls6 valley cover. Thanks for the link

What about the passenger side valve cover? I use that manifold port for my gauge, wastegate, and bov

Your passanger valve cover has two ports and your factory PCV valve is in the drivers valve cover at the rear? Could you tee off the rear of the manifold for the gauge, etc?

I personally dont believe in functioning pcv systems on these cars. I have been running 2 breathers for 8k on my turbo setup. No issues at all and best of all no oil at all in the intake due to everything being capped off.

I meant drivers side. I'd rather not pull off the manifold when its already functional. I'm going to have to get a catchcan regardless this oil is ridiculous

How many miles on ur car. I have low miles so hopefully no blow by problems. Ill let you know this week how it goes.

I didn't have blow by before, with just the na setup. 80k on my motor

I have two catch cans on my set up, one vented and one sealed and two check valves, so it vents to the vented catch can under boost and draw vacume back to the std manifold pvc location via the unvented catch can at idle and cruise.

This works perfectly,
engine has std type breathing at idle and cruise so no fumes and easy on seals.
Get into boost and the maniold check valve shuts and the vented can(large with two filters and two inlets) check valve opens allowing any crancase pressure to vent.

Note you need to block off the throttlebody vent pipe or you will just pressurise the crankcase under boost.

a bit more cost and effert to set up but well worth it.

^^ What about leading that line to the one on the throttle body instead of the one on the intake? Would that work?

Johnv

No there would not be enough engine vaccume, as that vents on the inlet side of the throttle blade not the manifold side.
