Possible for my 1g bov to be shot?

[BlackHalo]

Well, my car has been running like crap and holding no boost and i have a low vac. When i would drive and push the clutch in to come to a light the rpms would fall to 1 or 2 and catch itself and pick back up. I figured it was the isc... But i unpluged my vac hose from the bov and plugged it with my finger and blipped the throttle cable and the rpms would not drop down like it use to. So as is back to normal... So my question would replacing my 1g bov with a new one fix the problem and is it common or likely that this can happen? Just want to make sure its the complete bov that needs changed before buying a new one.

Thanks

Anthony

You should pressure test the system before you replace anything.

Search on www.vfaq.com and look for the "Intake Leak Tester" in the "intake" section. I guarantee that you will find a massive boost leak and you problems be solved.

Also, just look around your engine bay for unplugged vacuum lines that look like they belong somewhere Also, check your intercooler pipes; it sounds as if you have a massive leak. Start there before you start replacing parts.
