To be honest this has been leaking for a couple of years, It has a slight leak above the nut ( faulty seal?). I am wondering if this pipe goes into the Turbo at the back of the engine.

I am losing about 1 litre every 3 weeks. Not a major problem , its just the oil is burning and causing a bit of a smell as I presume its falling on engine or exhaust.

It is right at the back of the engine and in the middle.

I shall try to add a photo ASAP .

Im hoping someone will have some advise on what this pipe is for, also how to fix and how much.

Thanks Guys.
