The oil is from the the crankcase ventilation system.
The air mixed with oil vapours from the crankcase are inserted into the intake just after the air filter and before that funny "organ pipes".
So yes, there is a small, residual quuantity of oil in all the intake duct, up to the intake valves.
And the positive pressure after the turbo will force the air/oil out where the connections are not proper tightened.
Don't worry, there is no problem. It's normal up to a point.
The abnormality will arise when the oil presence and/or consumption will be appreciable. Then you can suspect the turbo seals.

Hi Guys

Are you talking about this area ?




If so I have the same.

I have another question : do you know the approximate quantity of the oil between the Min and Max marks on the dipstick ? (diesel engine)

Thx

It's 1.5 liters.
It is mentioned in that thing that usually collects dust... The manual, I believe it's named...

redge, it's normal, that oil quantity and location.
