• This has actually already been discussed here many times:

    If the 11 has been standing for a long time, the oil runs back from the tank into the crankcase and then usually from the leaking oil return pipes into the open air.

    Therefore, clean the engine from underneath with brake cleaner and look for the leak after a test drive or a longer standstill period.

  • ...the usual suspects can be:

    - timing chain housing

    - valve cover gaskets

    - "bermuda triangle" at the top of the thermostat

    - engine oil cooler

    - engine oil seal on the gearbox

    - oil return pipes 4x

    put cardboard underneath and see where it dribbles...

    oil viscosity 15w or 20w instead of 10w can help a little...ww

  • Hello everyone,

    Since I don't have a lift or a pit, I got under my car yesterday (as far as I could get).

    I think the oil leak is coming from one or both oil return pipes on the right side!

    Is it normal for the pipes to turn when the engine is cold ?


    Best regards and have a nice Sunday.

  • You already have "telescopic ones" on the left - fortunately you don't need to touch them.

    In your case, the "simpler side" is leaking.

    Two individual telescopic pipes costing around €30 each are sufficient for one order.

    Works like this.

  • Thanks for your feedback. Now I have an idea of what to expect!

    As I don't have the technical means to carry out the repair myself, I'll go to my trusted mechanic tomorrow.
