oil in cold side of turbo

[KurtsM5]

I took the intake system apart yesterday to clean MAFs, filters, etc. I felt oil in the (crappy) turbo inlet on the passenger side. PCV hoses are fairly new, replaced in Oct 2022. Got em from ECS Tuning.

All I can guess is the oil separator in the valve cover end of the hose is bad. Anyone ever heard of this?

EDIT---ECS is sending me a new one. Kudos to ECS Tuning!

Thanks for posting. What parts exactly did you replace? Either I have a set of turbos puking oil oooooor… it’s the same thing as you.

I have the same issue on the same side. I changed the PCV hoses, and had the turbos rebuilt and still have the same issue. The only thing left that I can imagine is the oil separator (11158636541), but I haven't gone down that road yet.
