Type-S is leaking Help!?!

[DSMBill]

Well I got a Greddy Type-S BOV and I already know by the guy I bought it from that it leaks at around 10psi, and I was wondering if I could adjust it to where it doesnt leak anymore, or perhaps replace something like a spring, if anybody knows what I can do to prevent it from leaking.

Tighten down the screw in the middle and only use the one vaccum source.

type s's are notorious for leaking at that adjusting screw on top of the bov body, some guys will put rtv silicone on the screw, and that screw it in. Or else you can drill out the top, re-tap it and get the right screw and put that in there... if that is where the leak is coming from, do that, if it's not then do what 94Jettameowpsst said in his post with the 1 vaccum source. I know there was a decent sized thread on here about type s's leaking and what to do.
