Does anyone have any experience with cleaning the fixed orifice valve on the 06 g6 GT with a 3.5. As I understand it the 3.5 without vvt wasn’t used long. I have an early model 06. My engine dosent have the pcv valve as I understand it. It’s non removable but on the front valve cover. I’m not having any problems but my car has 181500 mi on it so was wanting to make sure it was up to par because I plan to keep it a long time.
