Plan to decrease Crankcase Pressure, Pics included Options

[erics1one]

Well I think oil is being pushed out my turbo seals due to postive crankcase pressure, and I need to find a way to decrease the pressure. Theres a few different ways to go about doing this.


PCV Valve -> Turbo Intake AND/OR
PCV Valve -> Intake Pipe (my IC)

Currenty my PCV valve has a breather:


You can see the PCV Valve -> Turbo Intake setup here, which can be found on the stock 3sgte:



Some tap their PCV to their intake. The Injen Intake kit comes with a tap already in the pipe:



So I've been trying to decide what setup would be best with the equipment I have (5SFTE). Been talking to 'Byron' from mr2oc.com, he's knows his stuff when it comes to PCV stuff. I've been leaning towards hooking both intakes up. Was told here:

...that the small hose from valve to intake would decrease pressure during idle, while the larger hose from valve to turbo would decrease pressure during boost. Since I have a turbo, should I just connect the large hose to the turbo? Just connect a small hose to the intake? Split the PCV valve in two, running to both the Intake, and Turbo?



A: 5/8' hose to turbo
B: smaller hose to intake
C: one way valve

hehe we keep bouncing back and forth between forums...lol
anyway,
that spot where you tapped from isnt your PCV valve, if you follow the line in the pic (#10i think it was) back to the valve cover, the little plastic thingy the hose is connected to is the pcv valve. thats the one you wanna put the catch can in-line with, then to the intake pre-turbo like in your pic here..it'd prolly be a good idea to leave that line you have there connected too, or you could prolly put the breather back on it.
