Hello
Just wondering if this PCV setup will work or if anyone has tried it this way?

The Lines from the Valve cover run to a T fitting then into the catch can.
Then out it runs to another T fitting then one to the intake before the turbo the other to the intake manifold.


This pic was edited from another post I should changed the caption I guess.

Thanks

If you run it that way, you will need to install a check valve between the intake manifold and the T fitting. If you run it the way you have it drawn, you will be pressurizing the catch can and would also be losing boost into the intake pipe.

I run a similar setup except the out on my catch can only runs to the intake pipe which allows me to not have to run a check valve since the intake pipe never sees positive pressure.

Ok Thanks I will remove that T-Fitting. and run it just to the intake pipe.
In that case would I just cap off the fitting on the intake manifold?

So just breathing the cover to the intake pre turbo is enough by it self your saying. No need to have a check valve to manifold.
