Boost Leak Test=Leak out of BOV recirc tube

[Champ Masters]

Got a little problem. I did a boost leak test recently and I found that air was escaping out of my BOV recirculation tube. This is not supposed to happen is it?
The BOV is an authentic Greddy Type RS and I've messed with tightening and loosening the screw, but it still leaks out.
Could the BOV be bad? This would piss me off because this is the second brand new Greddy that I've had that has had problems!

Any info on this would be greatly appreciated. Thanks!

If you are afraid to do it yourself (or just don't want to) dejon make a "stop leak kit" that does the dodge garage mod but a little better in that it still actuates normally at low boost.

When your car is on boost, the pressure is the same on both sides of the BOV(valve and diaphragm), just leaving spring pressure to close the valve. When you let off the throttle, you're just removing the pressure from the diaphragm, but the pressure on the IC pipes(and vacuum on the diaphragm) will open the BOV. While doing the Boost Leak Test, you're basically doing the same thing, more pressure on the valve than on the diaphragm. You should try to somehow to equally pressurize both sides of the BOV while doing the test. If it still leaks, replace it.

BTW, each BOV brand is different. Some will open while doing the test, some won't. There are more facts involved here, like BOV spring pressures, diameter of the diaphragm, etc. But just try it.
