Thanks for the reply and clearly more investigation required.Is the wet patch coolant or oil? If its coolant I would say you need to investigate, if its oil it doesn't look like much of an issue most zeds have some small dribbles of oil, the milky stuff could be caused from doing short runs (condensate build up in the rocker cover) However if there is a coolant loss and its not external could be its internal and that's never good, that said I would suspect its not the case here.
