Hiss during boost leak test

I built the simple boost leak tester with the PVC cap and quick air disconnect. I found a couple of minor leaks on my boots, but there is a major hiss under and behind the turbo. I suspect it is the ebpv, but does it make sense that intake air could escape there? It is of course very hard to see, but I feel a definite stream coming from around a shaft of some sort, bottom passenger side if that helps.

First question, is this normal?
If not, is it the ebpv or something else?

Thanks,

Tony

Air hissing is normal. Hisses so bad you just shut off your ears and just look for soap bubbles..

I hear ya on the soap bubbles, that's the only way I found the minor leaks at a few boots. But the hiss under the turbo is a solid stream, can definitely feel it with your fingers under there... Doesn't seem that air should be allowed out of the system there, even if it's bleeding past a valve and going through the exhaust.

You can feel air with your fingers? I never felt around there, I just checked my boots. Curious.
