2013 GL350 70k miles Pressure Control Valve oil leak
So I think the PCV is leaking and dripping oil on exhaust causing fumes to come inside cabin when at stop light. Once driving it's fine. So question has anyone replaced this yet and best way to approach this? Also i got a CEL for P0171 System too Lean Bank 1 . Does anyone have printout of installation?
