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

wont you notice boost leak if you take into your piping and connect it to the intake end of your turbo?

Well as you can see in the pictures "You can see the PCV Valve -> Turbo Intake setup here, I believe this is the stock setup found in the MR2 Turbo:" They have it running to their turbo intake. Are you questioning this single line?...or that a vacuum leak would be created if I tried to do both?
