For what its worth, on my C900 I came to the conclusion that it was condensation on the engine block, built up overnight. Because:- 1/ I only noticed this in cold weather, when dew was likely. 2/ There was sufficient steam to indicate a leak, but no leak could be found 3/ The water level simply refused to drop a millimetre in a year of motoring. I don't like water or oil additives, if you really have a leak, you need to fix the leak not fill the system with crud! (does anyone else remember the Mike Harding sketch and the eggs in the radiator?!) Cheers Al
