whoa calm down tiger...
bov's will have air coming through with vacuum sucking on the nipple. how are you testing them...search this site, I'm sure you'll figure it out.

Put it in simple terms. is it the BOV the attached to the forward half of the Y pipe or the BOV that's attached to the back? Cause the back one is called a Charge Relief Valve & it does vent during boost.

ok ok if we're trying speak in stock terms, the CRV valve came black and the BOV came brown, lables and other jazz dont matter that was probably done by a previous owner. When does it leak air, do you have a boost guage?

All right. At idle the blow off valve will leak air because of the vacuum condition. When you start to boost the valve closes thus not allowing any pressure loss. My suggestion is to follow the blow off valve line back to the Y pipe and make sure that it is clamped down properly.
The charge relief valve vents the secondary turbos pressure until 4500rpm and then it closes as well.
Make sure that your vacuum lines don't have any cracks in them (the lines that go to the nipples on the bov and crv). Try that.

the vac line is really the only option lol, if you've tried 3 valves already and seen them work in other cars, then the line has to have a hole in it
or the actual piping that the BOV runs to the Y pipe with (rubber hose) has cracks in it and the air is actually leaking from that instead of the BOV.

Also how do you know its coming from the bov. To build pressure you have to be driving the car. If you have a boost guage "t" it on the bov vacuum line and see how much pressure is there. This will tell you the pressure in the motor.

yea just to clarify what crazyRX7 is saying ,
you will see the actual boost drop off on the guage as it vents out of the BOV or the spot that is causing the problem.
now let me get this straight, your attempting to do this while not driving the car? You should not be able to build enough boost in neutral to even get the BOV to close fully. You have to do this while there is a load on the motor.
