I just resently got a Greddy Type RS BOV in place of the Greddy Type S that I used to have.I stripped the top bolt out on the Type S where you adjust the BOV from soft to hard, my question is do I adjust it via the allen wrench hole or by the nut itself?I don't want to strip this one.Thanks.

 

The allen bolt. The nut on top is just a lock nut to stop it from loosening itself over time. Make sure to use a metric allen wrench if you've been using standard.

 

how do you know how much to adjust?

 

I didn't strip the top of the bolt.Somehow the bottom of it lost threading and blew off the bov when I shifted.

 

Where is the Allen nut? I think mine need to be harder, I'm pretty sure I'm leaking boost. Thats why I dont creep since my waste gate is not ported. I have small Allens around but no main Allan screw....unless I'm a retard and looking with my ***....
