They still leak and its not the way he has it hooked up that is causing the leak to happen, the factory PCV system leaks, its as simple as that.

I also want to add, that if you have a vacuum on you intake side of the turbo (CAI or SRI) you had better check your filter. There is no way the intake should create enough vacuum to cause any noticiable differnece in the crank case evacuation. I have tested this and with the proper clean filter and at WOT running full boost the intake doesnt make .2 worth of vacuum. Now with a dirty filter (different car) we did see 1.5 inches of vacuum, but that is not good for the turbo or the performance of the car. You should never ever see vacuum on the turbo inlet side of your system, it means you have a restriction somewhere.

I dont need the 90* piece on it or the rubber hose, and I have the barber connector already, I just need the CV. 40 for a part like is way overpriced IMO. ....Never would crap on PT, but I would like to hear an unbiased opinion

There was an indepent test that was performed on these about 4 years ago, search function and you should find it. The results were tested against 2 other check valves and ours killed both of them hands down.

I understand that you don't need the other parts, but we designed this CV for the masses, we have to buy them 100 at time in order to get the price down to the $40 that we sell them at, if not I have to pay $22 each for the valve alone, not including brass, hose, zip ties, assembly and testing each and every unit after they are assembled. Trust me, there is not a huge profit margin on these like people thing there is.

it has the volume but with the fittings on it may be 6 in long but it can hide under the intake manny

Pomz23 · 06-28-2009, 07:03 PM

Looks good to me. and in case anyone was wondering. The specs say opens on less than 1psi, but our gauges are in In/mg, So according to this site Pressure units converter | Convert to units measures. 1lbs = 2.04 inhg. Just divide the vacuum in half to convert to lbs. So that CV seems fine.

I run a grainger CV and have been for the past 3 years. Never had 1 problem with it. The one i have does not look like either of the links here. But its big. If i remember right mine ran me about $20-25 and that included the 3/8" threaded ends for each side.

I just called the company. Its 10$ a piece. They need a min order of 40$. So guys, if we can get 4 guys who want them I can place the order. It looks exactly the same as PT's and a 1/4 of the price.
