My greddy BOV is leaking causing me to be pissed off. The lower port doesnt hold vaccume or boost because it leaks causeing my wastegate not to open. I did the single spring mod located here EVO Motorsports - Evo VIII Performance Upgrades and Accessories - Type-S Single Spring Mod . It leaks mostly in vaccume or light throttle. As soon as im boosting it works. But having a leaky BOV sucks and makes driving horrible.

Should i get a new BOV?

Or tips on trying to fix it?

 

Figured it out. Had to adjust the screw. Sounds different but i liek it!
