BOV leaking???

[Spdrcr7882]

I did a pressure test on my setup, and found that around 15psi my greddy BOV starts to leak air. I tried tightening down the nut on the top but it still had the same problem. IS this normal?, it didn't seem like it was much air gettin out, but it kept the boost during the pressure test from going over 15psi, unless I put my finger in and held the round plate closed. Is this normal?

How much did you tighten the valve screw? The diaphrams on the Type-S's have a habit of going out sometimes. Try hooking up the smaller nipple on the backside of the Type-S. It will apply more pressure to the valve seat and cause it to close quicker.

THe screw on top of the bov I tightened down as far as I could, but it made no difference, so I put it back to where it was. As far as the back nipple I have it capped off now, and have the vac line going to the front. Should I put the vaccum line to the back and cap the front off?
