They are not in any way connected. The only thing that would make your stock BPV more likely to leak is age (wearing out), manufacturing defect or poor construction (which would mean it's already leaking), or running more boost.
I think my stock BPV leaks. When I get onto the highway I like to jam through 3rd 4th and 5th, and some days it just doesn't feel like I'm getting it all. Can't wait until I can get a Forge (was out of work 2 weeks).
