Help. Boost leak through PCV system
Testing for boost leaks in my system and have found a huge one coming from the hose behind the passenger side diverter valve. I can get some pressure in the system but it won't hold for any amount of time at all. I'm assuming this is some sort of PCV system? Does anyone know if there is a check valve for this or what needs to be replaced? I've done some searching but haven't found anything.

Well, found the issue. The check valve on the IPD plenum is junk. It tests fine with low pressure but one I put it back on the car for a pressure test it leaks. Going back to the stock unit until I find a better check valve.

Do you have any photos of this? What codes were you getting? Did you end up fixing it?

I have a997.1 with persistent p2187 p2189 codes. Trying to find a leak. I have ipd plenum and wondering if my leak at idle is the valve or something behind it
