Bov help

Long story short my stock bpv was making an annoying hooting noise . I had a knock off greddy Bov sitting in the garage and welded the flange on the stock ic pipe. Now I seem to get nothing but flutter . Bov doesnt move any air. Is there another way I should be running the vacuum line.?

Maybe it's the knock off bov.

Top screw looks like it's way too tight (too much preload on the piston)
Try backing that off a good amount
If that doesn't work then you may need a brand name valve

Thanks Guys. I messed with the Valve a bit but it made no difference in or out. I'll swap it out and see if it makes a difference

Could be. I know plenty of locals running them on High hp hondas builds with no issues. I wouldn't run it on my 600Whp Srt but on a car I paid 400$ for who cares.

The vacuum line needs to be on the manifold side of the throttle body. If you have it connected to one of the nipples upstream of the throttle plate it will do that.

If your stock line was in the wrong place you would.

Nevermind, According to this diagram i found all lines are run exactly where they are supposed to be. On a side note the adjustment screw had alot more soft adjustment then I had thought previously. I'll update tomorrow since i've had a few to many beers to give it a loop around the block

To update the thread. Once I had some time and after a good amount of research I found that The Bov was fine, I had to remove the helper spring from the Bov. There was to much pressure. Now it functions perfectly

Glad you figured it out! It's nice that you followed up, too many people come here, ask for help, and then there's never any followup for someone who may be searching in the future.

I would also like to ad for future reference, that while off-WOT performance will suffer slightly, you can run a piston-type recirc-made-BOV with NO SPRING. YES, NO SPRING. This is because it works off pressure differential, and not the actual pressure of the spring to seal. In fact, too tight is bad, because part of the reason for a BOV/Recirc is the pop open on blips to preserve throttle response, otherwise, you have to accelerate all the air in the circuitous intake manfild, starting from the turbo, then the intercooler, etc. This can make the engine gulp and then sputter.
All in all, it should pop if you blip the gas from idle. Anything more is too much.
