After months of my Cruze suffering from needing a new valve cover (ruff idle and all the codes listed here) and a V2 fix kit, i finally got everything together and got it done, rplaced both the valve cover and added the V2 kit to my intake.
The difference is night and day in how my Cruze runs now.
However, in my reinstalling the manifold and securing everything i ended up with a small black hose with green strips hanging in the very rear of the manifold and i must have broken off the plastic nipple for a portion of it was still in the hose.
After extensive looking i was unable to find where it plugs into, so i trimmed it a bit, installed a screw to stop air loss and secured it..
My question is, does anyone know where this hose plugs into?
Since there are more than 1 black hoses with a green stripe i am adding a picture of the one i know is installed correctly. (Passenger side looking down just behind and below the fuel rail, this one is secured properly,. So it's the hose that is behind the intake and below, that i am unable to figure out.
Any ideas would be appreciated!
Reason I am guessing that is because I broke the plastic nipple off mine when installing the kit and had to go get a new one. Also, if this is what you broke, I don't think i'd be driving it, this tells the valve on the turbo when to release the pressure if i'm not mistaken.
Thank you for the time! The small hose that wraps around from the turbo which goes through that solenoid and to a hise with a green stripe is intact and hooked up properly "see my pic" the hose in question is completely in the back of the intake manifold. The new code i will get and post today
Hey everyone, my Cruze threw P0171 last week. I looked into the intake manifold and sure enough, the orange check valve was missing. I replaced the intake, valve cover, and PCV hose, but now I'm getting a loud whistling from the new PCV/valve cover and a rough idle. Did I get a bad valve cover, or did I **** up something during the install?
Part numbers I got:
Valve cover: 25198877
PCV hose: 25193343
EDIT: Solved it! Valve cover gasket wasn't aligned right all the way around, there was a leak right behind the PCV vent. Not sure why this was causing the vent to whistle as opposed to the poor seal itself, but easy enough to fix.
