1999 1.8 Timing belt cover question - jp147
When I had the bonnet up on my Ford Focus 1.8 petrol, I noticed that on the Side of the timing belt cover a couple of small areas that looked darker than the rest of the surface of the cover (which is dark grey).

Now I am concerned that this could be engine oil and if so where does this sort of leak start and would it show up as a drop in level on the dipstick or could it possibly just be from rain water that has fell on it whilst the bonnet has been opened on a wet day ?
