I was at 12,500', 278 Kts gs, 31" mp, oil temp 180 degrees. Oil cooler door closed. I decided to see how much the oil temp would drop when I opened the oil cooler door, fully expecting to see some drop with an increased cylinder temp. When I opened the oil cooler door, the oil temp started to rise! It rose 25 degrees, and was still going up when I shut it. I did this twice-same results. I have one of the best sealed baffles in my engine compartment, so air leaks around baffles does not explain anything. Has anyone else seen this? David Jones, Pecatonica, Illinois l
