One of the by products of combustion is H20 - water vapor. It does find it's way to the crankcase.....perfectly normal. During normal driving in cold temps, it usually is "boiled off" when the engine oil and crankcase are at operating temps and leaves through crankcase ventilation, often routed to in the intake track. If you just start the car in cold weather and just let it idle, as some might do during winter storage, or just make a quick short trip with never fully warming the engine, you may see a bit of oily white foam on the inside of the oil fill cap. This phenomena is nothing new to Turbos, Porsches (air or water cooled), or even gasoline engines. It occurs with just about any internal combustion engines. You have notheing to worry about.

Now if you see this after prolonged driving, or in warm weather, check you coolant level. You might have a coolant to cylinder leak.

I just checked mine and was almost gone. I wiped the rest of the mustard out... Should be good now. I plan on an oil change soon as well.
