Turbos wet / oily
Yesertday I installed the Black Boost Cold Air Intake on my 17 C63 T-Modell.
When unplugging the original airbox and taking the chargepipes off, I noticed that both turbos were slightly wet/oily. Is this normal, or should I be concerned?
I haven't taken a photo bc my phone was not with me. But I will have to change the seals coming week and could take a photo.
Thank you guys for any help/advice.
