leaking stock bov?

i have a 92vr4 and i think my bov is leaking. anyone know any key things that happen when the stock one is leaking? like back fireing after wot or puff of smoke maybe? anything else would help to. thanks

You can hear it if it starts to leak. It makes this hooting/honking noise when you accelerate.

Sounds like you have a goose/owl under your hood when you hit max boost in 3rd. If you are wondering if it's leaking, it probably is.
