it feels like my bov is leaking with the nut all the way down....i run 12-15 psi. do i need to upgrade to a stiffer spring...where should the spring be set at with the standard spring....all the way down, halfway or all the way up..i have no clue. thanks in advance. kevin.

If the screw adjustment is all the way up, then it will release with less pressure causing it to leak. I have mine half way.

thanks. https://www.nopistons.com/forums/pub...#>/biggrin.png

I've found that at that boost pressure, the blitz bov tend to leak, even if it's new. https://www.nopistons.com/forums/pub...DIR#>/wink.png

go with a TiAL bov https://www.nopistons.com/forums/pub...#>/biggrin.png

my greddy type r doesn't leak

Neither does mine. I always advise people to get the quietest BOV since the louder it is, the more work it is doing. https://www.nopistons.com/forums/pub...O_DIR#>/11.gif
