Firstly its not a BOV as such its an over preasure valve. Its there in case you have problems with the waste gate and so as not to allow the turbo to over boost this valve will let go. They let preasure go at about 11lb of boost. Mine was blowing off all the time so I pulled it out and welded it shut (no more Pshhtt noises and boost drop) wahoo.

remove it completely, and put a big brass bung in there instead. Take it to your local plumbing supply store to find something with the correct thread.
