Chevrolet Malibu Coolant Problem
Car has a slow coolant leak that I haven't been able to find. When I checked the oil it appears to have water in the oil.

The head gasket may be in peril. I would recommend pressure testing the cooing system overnight with he spark plugs out, then in the morning, hit the starter and see if coolant comes out of the spark plug holes.
