Can I just use one Supra PCV to connect two different of vacuum hoses in this DIY project???
Here is the pitucre I'm talking about:

mine didn't leak any air on the direction the valve is supposed to be closed. I got two and set it up just like the crank vents with one going to the valve cover and the other to the intake, worked fine.
to me it's kinda dumb to add a leaky valve to replace a stock leaky valve, in the end you still have the same problem. if you get one and it's leaking in the direction it's not supposed to then order another one

So if i'm understanding this correctly, both new pcv valves will be letting ar out of the crankcase, but not letting air in so that it builds up negative pressure and good seals?
What's the advantage of putting a breather filter on the intake breather line instead of keeping it to the intake pipe? Is it something to do with keeping the extra oil and junk out of your intake?
If it doesn't help that much,, i think ill just leave it . i have an injen intake and i dont know what i'd plug the hole with.
I mainly want to do this to help my oil consumption. I recently replaced my stock pcv witha autozone one, but it seems to let a little air through the wrong way (not good).
Thanks for the link. Much appreciated
the one going to the valve cover keeps air from entering the motor from the intake manifold, more of a problem when boosted than all motor. the second valve is what actually seals off the motor and creates the vacuum with there's vacuum in the manifold. the second one going to the intake will help create a vacuum in the motor when you're at full throttle.

I just picked up 2 today (the last 2 they had) from advanced auto parts. I guess they are paired with partsamerica.com and i was able to go pick them up at the store.
2.50 a pop is pretty damn good when the ones on google shopping were 7-9 bux
Im new to the FI world. Im getting the sos sc. From reading this I looks like i need to change out this valve....right?
What is the diffrence between Hokies200 and SgtB methods?
dsddcd, now what is that that you did? Looks easier than the others

The idea is keep pressure from entering the crankcase by putting in a check valve.
