how do you install a Greddy Type-S BOV??

I have the BOV mounted, and the guy who installed my turbo said that it’s connected right, but i already loosened up the bolt the loudest and it STILL doesnt make any noise!!! Someone please help!! One of the vaccum lines is connected, but the other’s not. Are both of them supposed to be connected or what??


Are you sure your getting boost? Maybe you have a leak. There’s only 1 vacuum line you connect (the top nipple to the intake manifold) The bottom one on the BOV is left open. On the softest setting(adjusting bolt-loose) you should here blow off in Neutrel under wide throttle, REV the engine really hard while listening to the BOV. My thoughts are you have a leak somewhere.
