It won't take care of the issue.If it leaked, you would not hit fuel cut, you would just feel a dip in power. Besides, I thought you had a boost gauge?
yes and no...if its leaking back into the recirc that runs back to the intake then there would just be a loss of power. But if the valve is leaking to atmosphere it could deff. cause other issues
a leak under vac. will pull in un metered air, causing a lean condition. a leak under boost will do just the opposite. there will be metered air leaking before it makes it into the maniflod. this will cause a rich condition. and considering how rich this car is already at WOT, it could very well cause an engine misfire, due to a flooded cylinder.
Can you post any pictures of the problem then post a picture of it fixed? I can't picture any of this in my head. Are you talking about the part at the top where the recirc tube is attached? I know that part can spin if you push inwards on it since it compresses the spring, but what you're saying is that it's broken or not on correctly if you can move that top part while the BPV is screwed on as tightly as you can get it?
not the top, the whole valve itself moves. You know the thing u screw onto your intercooler, thats the flange. The cylinder looking thing wtih the two hoses attached to it, one on top one bigger on out the side. Thats the valve that moves independent of the flange. Try turning it, and use some muscle
Thanks, I know exactly what you meant now. I'm gonna check that out tomorrow morning. I need to change my spring anyway. Ever since I got the ETS intercooler i've been getting fluttering in 3rd and 4th while using the blue spring. It only really happens between 2k and 3k rpms if I let off the throttle. Gonna try yellow with two shims and see if it still flutters.
I thought when you hear a fluttering noise that it is comp surge. It sounds just like the fluttering from some of the comp surge videos on youtube, just doesn't last as long. It only makes about 2-3 flutters.
Could the cold weather have made it start fluttering? I could have sworn that during the summer when I first put the ETS intercooler on that it didn't flutter using the blue spring.
i cant tell you what you have by reading a post. i can tell you that nobody has reported any surge with the blue spring before. it is common to hear a fluttery sound from many bov's while venting a small amount of boost. it is the sound of the piston opening and closing because there is not enough boost built up to make a forcefull exit.

I tried to muscle the valve last night at the track after my first run. It definitely turned. I put the stocker on again. I'm wondering if I should send Forge an Email?
i dont know what that would do for you. i,m sure they are tight when they ship out. after going from hot-cold and getting shaken around they probably just loosen up a little. if it continues to loosen up, that would be a problem. i think if you tighten it up once, it should not be an issue any longer.
