BOV question

[Puscifer]

K, I'm going back over the vacuum lines dealing with my MBC and BOV. I've got the MBC figured out. Two lines = W/G and Turbo, j-pipe or LICP. Now I've looked around and tried to get pictures of other members rides but their vacuum line off the BOV just disappears somewhere near the intake/TB.

Where do I attach the 1 single vacuum line from the BOV to? looks like a stock bov but i'm uncertain. Thanks in advance.

The source for the BOV needs to be after the throttle body as the change in pressure is what causes it to open. There should be a barb that is tapped into the intake manifold that is meant just for that purpose.

Alright, thanks. The difference between Atmosphere venting and recirculating i've noticed is a very wide situation. From the setup this car previously had it was vented to the atmosphere, very loud noise as well, nice little pssh sound. Now, the question at hand. If i go back and put this system to recirculate and it was previously setup for atmosphere, would i need to change anything else? check anything else or is it just a simple switch over of the vacuum lines? I really don't give a damn if the thing makes the noise or not. Less attention for me to handle. Just want to make sure i don't mess anything up. Thanks!

Unless it's got a GM sensor and a MAFT translater, the car was never "setup" to vent. The only way it would be without those, is if the BOV it had has two dumps (one to a recirculation tube, and the other vents), but you would know if it had one of those.

Even with one of those BOV's, I'm not sure if it would be able to properly vent without pissing off the maf sensor.
