Oil/Fluid leak

[Meteorological]

Hi All
My 2004 berlingo seems to have developed an oil/fluid leak,its coming from the rear of the engine bay, its no engine oil and the fluids seem to be at the correct levels, its off to see my mechanic on wednesday but I was wondering if anyone on here had any ideas.

The fluid is coming from the rear of the engine bay to the left as you look from the front.

If the oil is dirty,it's engine.If it's clear it's transmission.If it's red it's PAS fluid.alut:

Could be diesel if no fluid levels are dropping. It will pick up loads of muck on the way down and be impossible to tell it's diesel.

I believe it is most likely to be the rocker cover gasket if it is engine oil though.
