I've seen this on every air-cooled car I've owned. You only get "excessive" water if you never let the engine warm up fully - drive a mile and shut it down kind of thing. The water comes from piston ring blowby and is one really good reason to change oil regularly - the water and other blowby gases form acids that will eat your engine in time.
I had a 36 HP motor that had been sitting with the old oil in it for a few years before I got it - the bottom of the crankcase was deeply pitted from that acid. This was with the older magnesium alloy - newer aluminum cases are not as sensitive. Change your oil and take the car out for a couple hours every month or so - the buildup will be less, but you will always see some foaming on the oil cap. Nature of the beast.
