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

If your on the stock turbo with stock lines (assuming your oil drain line isn't plugged)... you turbo may need service. And its not the seals that are normally the problem... if any of the bearings are worn or even just a little groove will make a seriously smokey turbo if left unchecked. It can feel plenty tight and still smoke like hell (feeling the clearance is a big waste of time anyhow).
