I am going to be doing this mod tonight. I have not yet had any blowby issues with the stock PCV but im at only 7-8psi and im going for more boost next week so i figure this couldnt hurt. I ran a regular plastic ( but for a turbo 323gtx mazda ) PCV on my turbo miata for years with no issue as well.

 

You can use this mod in conjunction with a catch can, correct?

 

[QUOTE=SgtB,Nov 6 2008, 01:48 PM] There is neither vacuum nor positive pressure in the valve cover due to the wide open breather line running to my intake. The oil drains being in the head vent the crank case as well.

 

 

Yes you can use it with a catch can. It would separate any oil from the stream.
S-turn: I was boosted. It prevents positive pressure in the IM from coming up the pcv line into the head. I don't run a second one because I want the pcv system to function as stock. The reason I run a supra valve is that the stock valve is weak. An oil separator on the breather line will catch any oil headed for the intake.

 

I see now... so your using it for something completely different then what i and other N/A guys are using it for. so you don't have an oil consumption problem ?

 

i don't see how this will work unless if you remove the s2k stock pcv valve in the first place,

 

Why wouldn't it? Isn't the goal to prevent pressure from IM?

 

Mines doubled up with the factory pcv and the supra inline. Logic would say = that much more protection.

 

not if the stock pcv still there
