Chevrolet Cruze LTZ 1.8 Ecotec, gas (MT)
Code: P0011
Hey everyone, I'm completely out of ideas with a persistent P0011 code. Here is everything that’s been done so far:
Oil and oil filter: changed (5w30 ACDELCO, GM filter)
VVT Solenoids: Replaced with new ones (and interchanged them to troubleshoot. the code stayed on the intake side).
Check valve: Replaced the oil gallery non-return valve located below the alternator.
I took off the upper timing cover and discovered the goddamn previous mechanics used the wrong tools and completely butchered the bolts on both sprockets (cam phasers). That said, they aren't leaking oil and they don't wobble (at least not so I can tell)
When I clear the code, it takes about 30 minutes of driving before code pops up back again.
My next thought is checking the mechanical base timing and replacing the VVT intake sprocket entirely. I also have several videos of the car starting up if anyone needs to hear the cold or warm start audio to help diagnose.
I really want to fix it and get rid of this piece of sh*t.
Thank you all for your help in advance, truly.
