If it is the turbo itself . It should be covered under power train. It's a major component on this engine . If not I'll find another solution . For now the turbo is making boost. Also I have no smoke coming out of the exhaust. I'm only collecting oil at the turbo inlet and it's carrying over into the intercooler piping. That's what originally led me to believe it could be excessive crankcase pressure causing the seals to leak on the cold side of the turbo.

Thank you for reply. I was thinking it might be a pcv issue. The dirty side of the pcv system feeds from the back of the engine to the turbo inlet. Makes more sense the turbo could be the issue as these engines have a built in air/oil seperator on the back of the engine. I'll try and get mine to the dealer .

I have a 2020 2.7 silverado and I'm having the same issues with oil in the turbo inlet and intercooler piping . My intercooler pipe looks just like yours in the picture you posted. I currently have 56,000 miles on my truck. Have you gotten any answers yet on the cause? I'm currently looking into installing a catch can.
