Message I am hunting a boost leak that seems to be coming from under the plenum. When pressurizing the system i have air blowing from the opposite side of the PCV valve treads in. I almost thought it was the driver side turbo outlet hardpipe leaking and removed that, thats not it. The nipple on the inlet pipe is capped.

From photos i can see online there is one hard line under the plenum that is not a water line on the drivers side? what does it go to? maybe i'll bypass it and see if the leak goes away.
