bov whistling

[14u2nV]

My Bov has started whistling pretty loud at idle. I have maft/blow-through, vented to air and it is a crushed stock. When I reach down to the outlet, it is blowing air out pretty steady, and whistling loud enough to annoy. Is this a bad bov? What else could it be? Vac is good, pulled the line off the bov and checked for suction.

Does it still blow air out when you have the BOV line disconnected?

Sounds like its leaking. Time for a new one

Quoting Barnes:

a little, but not much.

Yeah, I was affraid that meant it was going. Guess I'll look for a new one.

I had similar problem before. I had broken silicone hose. Check the boost if not boosting means leak, If much boost then your turbo actuator or wast gate is not working for some reason.

boost is fine, getting around 14psi. No broken lines, just leaking out of the bov.
