2000 Dodge Intrepid Excess Water (Not Coolant) in engine oi

On our 2000 Dodge Intrepid we brought it to a shop for a routine oil change and they said the oil was very creamy looking and there was alot of it. They did a few checks in the shop to check for coolant and it did not appear to have any in the oil. They sent a sample out to be analyzed and ran a diagnostics (computer scan) and came up clean. While waiting for the results we needed the car for my wifes work within 1 week and 9 miles the oil was already 1/2 quart fuller and creamy looking. After getting the results back it showed NO coolant No fuel but excess water. The car returned to the shop to look again. They checked the PCV valve and found the hose and valve to be faulty. Besides this they could not come up with an answer. We were given the car back and told to watch the oil. Now we have had the car back three weeks and the check oil light came on yesterday. I checked the oil, it is creamy and is over full 1 - 1 1/2 qts.
We live in Northern Minnesota and my wife works only 2 miles from our house. So the car is used in short trips and only allowed to warm up slightly. But she has always driven this pattern for the 7 years we've owned the car.
