I'm a new here and was really hoping someone out there may be able to shed some light on a mystery oil leak we have on my wife's car?
We took it to Audi and they wanted nearly £300 just to investigate the problem, so I took the car to a trusted mechanic who we have known for years.
He changed the rear brakes, MOT'd the car & even cured & found a coolant leak we have had for the last 6 months from the back of the engine & in the same area as the oil leak.
However, all his efforts to locate exactly where the leak is coming from have now drawn a blank (even after having the engine steam cleaned as good as new).
He replaced the rocker cover gasket and thought he had cured it, however after a short test drive, the leak has appeared again?
I will try to get some photos of the area, but in the mean time I will try to explain where it is.
Its high up on the rear of the engine. there is a metal pipe that kind of runs right around the engine to the oil filter and it is dripping ONTO that.
There appears to be a sensor on the top of the engine at the back, secured with 2 x star screws (possible cam sensor??), we believe its coming from under that or in that sort of area? Its so cramped for space behind there and even with the use of a small mirror we just cant pin point where its coming from?
Its not a pumping out leak, more of a slow trickle.
If anyone can help to shed some light on this it would be greatly appreciated. We are looking to sell the car now and we want the peace of mind that the oil leak has been found.
