Blow off valve not working...

[Not7fifteen]

Ok i have a crushed 1g BOV on my 90 talon AWD on my dejon tool MAFT upper IC pipe. The BOV doesnt release the preassure fully when you let off the gas like it should, instead I get bad compressor surge followed by a delayed whistle out of the BOV. The vacuum line is hooked up to the intake manifold vacuum with a new line and new connecter. The BOV sat for 10 months while my I was without an engine, could this have made it seize or made it go bad? Should I just spray some lubricant of some sort in the BOV?

I have a Turbo XS RFL sitting here but I don't like how loud it is plus I'm running 18psi on a 20g and I dont know how much boost they are good for and I really didn't like how loud it was, hence the reason I took it off.

Anyone know what could be wrong with my 1g BOV?
