Ok, I think the problem is the BOV may be leaking?? But this is what its doing: At idle there are no apparent issues, start driving and its fine, shift at low to regular rpm's and everything seems ok. But as soon as you start getting on it and shift the BOV makes its noise but seems to "whistle" out until the noise goes away. Seems to me like the valve is opening but takes a while to close back up....or maybe not reseating at all???? LMK, if anyone has any ideas on this? Could I need to replace the springs inside? Am I loosing power because of this? (it seems to be running strong)

I mean, yeah? This is REALLY hard to explain by spelling it out? It makes a normal BOV sound which lasts a max of 2 seconds, you know, the sudden release of all that pressure. But AFTER that it seems to "Whistle" An ENTIRELY seperate sound, that is like a Human whistling starting at a high pitch, and desending in tone quality until its gone (maybe 5 seconds?). Really wish I could post the sound somehow? But thanks for the responce!

If you are ever near Columbus, I'll take a look at it for you. If you lived up north I'd help you personally. Maybe we can make a meet outta this and work on a few cars.

MK_94_3000GT , DUDE, I have been waiting to meet you for a WHILE now anyways. So why dont you come to the Car Show on Friday in the K-Mart parking lot? Me, Mobius, and I think this memeber named Fiji Blue Something are gonna go. You should come! Hell, 4 cars there would be a good start for a Stealth/3000GT Representation! But we would have to get there around 4:00 to get 4 spots next to eachother.......I SAY ITS A OFFICIAL MEET! And yeah, then we can take a look at my BOV deal

Can't man, I've got some shit to do up here this week. Although you should go to the Street Life Tour Saturday at Kilkare. My friends and I will be there for that one. I'm bringing the VR4 for that too. I can bring my RS BOV and SSQ and you can put them on there and see if said problem goes away. I could even put yours on my car and see if it still makes this noise. Yea I'd love to meet more Ohio3S guys.

I'll be there all day. Its the host of the Street Life Tour so its gonna be pretty big. It starts at 2 and I'll be there for most of the day, and pending on if I bring the woman or not I'll stay as late as possible. I'm not gonna race the 91 because I didn't register in time, but I will be.
