I have had oil in the charge pipe since my truck was new in 2020 at the first engine oil change. GM stated that they didn't know why it was happening. Checked the turbo-okay, checked the PCV system-okay, all other items were fine. I took the truck back at the next service and GM sent an upgraded charge pipe to try-no change. Took back at the next service and was told by the dealer and GM that it was just how the engines are designed and there was nothing they were going to do. I work for a Euro repair facility and work on a lot of boosted engines. So, I installed a catch can and sure enough, the PCV system was allowing excessive moisture past the separator. We have to empty the catch once a week in the winter as it fills so quickly. I don't short trip, use only MOTUL engine oil, and Top Tier fuel. Bottom line is, GM isn't going to fix it or even know why it is doing it. Invest in a catch can and take care of the problem yourself. I would recommend the J&S catch can with the extension.
