I'm not too worried. I run higher than normal temps in my TDI(205-209 F) so the water will be vaporized and flow through the CCV into the intake. Also, from what I can see the oil collected is very clean, and I strain it to make sure. remember were only talking about a little over 1 ounce per 10K miles.
