Blow-off valve

[Boostedh22]

Anyone know what would make a Blow-off valve stop working, now only the wastegate opens up. Its less then 6 months old.

Hmm, what valve do you have? If it's the HKS super sequential, I have no clue. If it's like a greddy type S, or similar valve check the spring, or see if the adjustment screw is too tight.

my roommate has had two bosch BOVs crap out on him before he finally got a forge... I dont remember exactly what went wrong with them, you'd have to ask him (saabracr)

Which valve is it? If the line from the intake manifold to the valve is bad/has fallen off/etc, the valve won't open.

I'd suggest taking the valve off the car, and using a vacuum pump on it to determine where it opens. Is it adjustable?
