WTF! Stupid bov! Or stupid me? My bov is opening before it even reaches boost.
I can hear it starting to crack open when the car is still in vacuum.
Its a billet bosch style bov. Could it be defective? I have it about 15inches before the maf sensor.
Wut the hell am I suppose to do now!!!???

Oh yeah! Info about the car would help! I am a genius!
Car is a turboed lt1 impala. I'm actually not sure wut spring is in the bov. The vacuum is referenced from the drivers side of the intake manifold. I have I T'd at the vacuum fitting.

is the bov opening under vaccum at idle? or when you start to accelerate before you hit boost? i'd check/swap out the spring and see if that fixes it.
do you have any pics of the bov? i tried to look up a picture of it but couldn't find anything

No its not opening up at idle. It opens when I accelerate before I hit boost.
This bov is like solid. I doesn't have any screws or clamps on it. I really don't think that it opens. I can get a picture up later. If u were to goto hp performance.com they have a pic there. They use it on there twin turbo impala setup. They call the bov's billet bosch style. I've seen a few ls1 guys use it here on the forum. (Can't remember who tho)
They definitely have there's mounted further away from the throttle bodie than I do tho.

The BOV pictures on that website are conveniently not working. If it is "Bosch style" it is a compressor bypass valve, not a blowoff valve and it is entirely possible (and easy) to install it backwards. Flip it around and see if it works.
Edit- Look on this site- http://www.s4biturbo.com/art-dvtests.php pics with in/out arrows...

Thanx a lot 05hd!
The one I have looks really similar to the aluminum looking one but mine has like fins or something around it.
I can't figure out how to post the pics of it.
I had the short end mounted into intercooler hose and the longer end dumped to the atmoshpere. If I'm reading those arrows rite, it looks like I had it backwards.
I"ll change it around and give u guys an update.
