My 96 850 n/a with 260K has milky oil in the dipstick tube. This only happens in the spring and fall when we get the large temp swings (35f at night 75f day). When I change the oil, there is not water or milky substance in it. Inside valve cover is clean and it uses no water. The car is parked outside. This only happens in the spring and fall for about a month. I can only assume it is from condensation? Has anyone experienced this? Am I missing something. They car runs great! It uses about 1qt of oil in 5K miles. The milky oil is only in the top half of the dipstick tube.
Thanks,
Keith
