Hi,
I have a X-BOW RR. Last week I was changing the motor oil and noticed an oil stain on the inside of the rear diffuser near the right rear wheel. When I looked up, part of the steel chasis above the stain was also covered in oil and it all seems to come from a line feeding into the turbo. Now the car is in my garage without the rear diffuser installed and a couple oil drops emerged on the garage floor. Is it normal or more likely there is a problem with the turbo? In one youtube video about motor oil change in X-BOW there was the same oil stain as I have so perhaps this small leak is normal? I drove the car after the oil change and it drove great..still feels crazy fast :))
