Hi all. Checking my wife's oil a little over a month ago and I noticed a milky mixture on the dipstick. The milky mix stays above the oil level and does not appear to contaminate the oil. The oil stays clean, since I have checked it weekly and did a change last week. The PVC was cleaned out as well and it also contained the milky oil/water mix, but still the oil stays clean. Obviously there is a buildup of water vapor in the crankcase and the only area it can condense is in the cooler dipstick tube and the pvc hose going to the flame trap. While looking around here I saw another person with the same problem but there were no solutions given except clean the PVC(flametrap) which I did. Does anyone know where the water vapor comes from? Can it be reduced or eliminated? Where should I start on this one? We are in NJ but I have never noticed this problem in winters past. Thanks in advance!

Tell your wife she needs to drive her car more. Not enough heat is building up in the oil to evaporate the water. That's all. But, you are creating an atmosphere to create sulphuric acid build up which will pit the aluminum crancase and other parts, so change the oil more often.

Thanks Klaus,
After thinking about it I did realize that in winters past my wife worked a good 20 minutes of highway driving away. Now she only works 5 minutes away on slow back roads with a max speed of about 40mph. As long as head gasket and head are ok, we'll be fine. Thanks again!
