So. i got a real type S because i just like the sound. and ive tried fully "soft" and fully "hard" and all between. only thing this BOV will do is my a flutter sound when mid to hard. Around soft, its just an airy sound. Diaphragm looks good, and i have it tapped for vac on my PCV hose. It was used, but is in good shape.

Any suggestions?

 

I had that problem with my knock off. I had to remove one of the springs for it to work properly.

 

Cool, thanks, i'll check it when i get home.

 

correct flutter sound means the air is not getting out. spring too hard. Up the boost or change the spring.

 

take a pic of your engine bay so we can see how you have it hooked up
