Hope its not something more sinister like a wheel let go.

I have a gfb dvx diverter/bov in place of the oem borgwarner bov that's part of the compressor housing and it has been working fine, well it wasnt opening under boost and causing a big boost leak. I was suspect that it could have been leaking and I had pressure tested turbo pipework and checked all plenum hoses and fittings and found nothing. I took dvx apart and put in a extra spring to make it really stiff and hard to open. It fixed it yaaa, I havnt had much luck with bovs on this barra, my Greddy type r 50mm leaked and when I put a stiff spring in it wouldnt open and this dvx has started to leak after a short amount of time too.

Best just to have no BOV,

Yea im slowly working that one out, they seem to be more of a problem than anything else. Do you guys know that the stock xr6t bov piston actually runs sideways so to speak so the piston cant actually be pushed open by boost pressure, it could potentially just leak past the o-ring that seals it when its shut. Not sure if other oem bovs work like that but it seems like a pretty good idea to me. Aftermarket should make them like that. I might chuck the stock one back on and see how it goes.

The OEM BOV is designed to trigger itself opening when vacuum is applied to the port, e.g. it'll hold closed until it see's a vacuum source (assuming the seals around the piston are holding the air from getting past it, which is the only weak point), not like other BOV's that use a spring to hold pressure against boost.
