does anyone have any easy way of testig a 710N BPV to see if it is leaking? I installed a new value about 6 months ago and now I am seeing my boost bouncing alot at WOT and the car is surging. All I have is a neuspeed chip so I would assume the 710N should be enough. If its not the BPV leaking boost its probably a hose somewhere and that would be a lot harder to find. So if anyone knows how to test a BPV please let me know.

put finger on vac nipple to seal it, and release piston.

If the piston returned to it's original position, it's bad.

If the piston hold it's position while your finger is on the vac nipple, it's good.

I've heard the simptoms your describing with people who have installed the valve backwards. Make sure you installed correctly

I installed mine exactly like the original one that I removed. I have heard of people putting them in backward on purpose but I'm not sure why someone would do that. How do you have yours oriented?

I'm confused by what you mean by "release the piston" I know the nipple that you are talking about, but I'm confused about what I need to do with the piston.

Stick your finger in the hole, and push.

orientation, but I think you did the right thing.
