Hey Alex, let me know if this actually changes the sound.

The TT makes the sound so much louder with the free BOV. No kidding, now I can hear some turbos.

I am going to cover one to see if forcing all the air out of just one valve will make it louder or not.

if you shift without taking the foot out of the gas you won't hear anything.

I believe they are not. They use the same connector as the other end.

Take your time and you'll be able to just turn them. It's kinda hard though at first.

Squeeze the white/greyish part and turn it clockwise, or to the side that have space in between them...the hose will pop out... If you squeeze the whole thing it won't move, only squeeze the white part of the diverter's valve end and it'll just slide out...give it some force too.

Remember you do not disconnect it from directly under the DV!!! Disconnect where each hose meets the pre-compression ducts!

i did this to check it out today, see if the whole BO sound was as gay when its in your car as it is when you hear it on another peoples cars... i dont think its for me (especially since if your trying to cruis @ 60 you get a light woosh thats really annoying whenever you go from tiny bit throttle to none)
anyway, a few things occured to me, 1: the engine bay is hot, dont forget some materials will probably melt, i used 1 inch ID vinyl tubing and a pvc end cap (least ghetto i could think of, no electircal tape, i bet it would NOT do its job after heating up once or twice) after that i noticed something else, between shifts it doesnt bleed all the pressure just a quick pop then it closes again, but if you leave it in gear it will stay open, seems like when its out of gear theres less vacuum as the engines reving down rather then being held at higher speeds by the wheels; and if this is true, then theres no way in hell its going to pen any other time and suck air in (that was pretty dumb idea in the first place) besides that i liked it more than i thought i would, but not enough to keep it i dont think

What's your theory on the valve dynamics you mentioned? Why would it behave differently than the aftermarket BOV's? |

Dang it, my fingers are getting jacked up from trying to pop off the diverter valve... The thing won't come off. I wanted to try this trick just for the heck of it. Do you pinch the Arrows or the tabs inside the slot opening?
