TD5 oil leaks

All

I know TD5 Landrover's all leak oil and that's not an issue

my gearbox box dribbles
my transfer box dribbles
the front engine oil seal dribbles

BUT I appear to have "more than normal" leaking from above the alternator I can see the trace coming down the block and around the mounting points..... is there an oil feed up there ? I have jet washed the engine before to have a look but as you know its almost impossible to tell where it is coming from.

The other wierd thing is its completely clear, so could it be clutch or brake fluid ??

STOP THE BUS....... will check if its derv leaking after reading links about fuel pressure reg and gasket issues
