Pretty well standard, its due to the engine breather system venting into the intake.

Both turbo diesel engines here do - Citroen and Toyota. Amount is quite small, just enough to put a thin coat on the ducts, and a few drips in the intercooler.

Hello everyone.
Thank you for your answers.
I had a 4x4 Mitsubishi Pajero / montero and the engine had a reservoir called oilcatch. Have you heard of it?
it is a reservoir that connects to the breathing tube of the engine that goes back to the intake. this reservoir has a filter and the oil is retained in it. so the air circulates clean. do you think an adaptation for the citroen would be a good idea ??
thank you for your help.

greetings

On a turbo-diesel, a moderate amount of oil in the intake ducting is not a problem.
If the amount of oil builds up so that drops/drips form, they will get harmlessly swept into the engine, and burned. Diesel engines are, after all, oil burners! There is no need to collect it, or drain it off, unless there is a really serious problem.
