I'm pretty sure this has the same flange on it as the Greddy valve. I think I even have a Greddy valve sitting around somewhere that I might throw on there. The 135i that has this set up on it runs at least 15 psi and hasn't reported any leaks however you are correct. This is a China BOV and like everything else China, untrustworthy.
