Finally got around to tackling the timing belt on my Xantia (2 litre 8 valve petrol) and found this:

Looks like the water pump is leaking
The brown substance is sticky gooey crap which I presume is leaking coolant mixed with grease and oil ? There is enough of this stuff built up that the edge of the belt is actually running through it!
Oh and by the way I notice exactly the same problem DoubleChevron had with his - the timing holes don't line up.
