Well, it’s another Saturday and another forced project. My Mother-in-law pulled into the garage and I could hear her Buick from inside the house. She comes in stating that her CEL is on and the car is running rough.
The look on my face as I’m pretty sure what the problem is going to be.

So I go out and pull the codes, and sure enough, it’s the codes that I was expecting.

So I start it and you can hear it sucking air like a Hoover through the cam cover. So I shut her down and upon checking for the visible check valve in the intake,..gone. The PCV hose going to the turbo inlet can also be blown through in both directions. Complete failure of this garbage PCV system.
It’s amazing that this car was driving fine right up until this happened. She says that she was sitting in the Chick-fil-A drive through when her CEL came on and it started idling rough. I drove it a couple of weeks ago and not one thing was amiss.
Anyway, I ordered everything From GM and went to work. I kept the old intake as I have seen something about a kit to modify it to avoid this problem that WILL come back. I’ll have to research that and see if it’s a viable option when this happens again.
GM should be ashamed of this garbage. I’m not a manufacturer basher, but this PCV system sucks! (Literally
