Greddy BOV issue
 

ok first of all as you might know im doing about 10-11psi and on a rare time 12psi. but also some of you have seen the new IC pipe setup i have going. but my main issue is that my Greddy RS BOV is opening at around 4krpms during load. so driving on the freeway i can hear it whisteling while im driving. what you guys think i should do about this problem?

Are you sure it's the BOV and not a leak from the flange? Otherwise, I'd take it apart and either get the spring tested or just replace it.

Sorry, I don't know too much about the mechanics of a BOV.

yup im sure its the bov, just because i can see the valve opening. the gasket is fine. sping tested WHAAA? replace it with what i dont think you can replace it. i think im screwed with getting another one HAHA

Trust me on this: Don't take my word for it... get a second opinion. ;)
