Water in the rear engine.

Here's the new news. 10 hours of flight - Oil temp running about 180-240 whole way (needle right over the white line). Head temps 330-370. Running 24" and 2400rpm. 50 degrees rich of peak. 12 hours total on oil. Temp switch checks out. We drained 8oz of water from the sump. What is the deal!!
