hey guys.. i've had my evo for a few months running stock except for a worx tuning bov.

i performed the regular maintenance on the bov and as soon as i put it back in i got a boost leak. at wot, around 5-6k rpms, i hear air escaping and i can see my boost drop. i tightened the spring setting three times taking it out and putting it back in with no luck. i finally put the stock valve in and i'm still having the same problem.

any ideas? thanks..

try this it might help to make sure it is leaking at the BOV , or it might be leaking somewhere eles
