Had a beautiful day on wednesday 65 degrees and clear skies so opened the hangar and brought out the plane for a short hop after the long winter.
Preflight went normal and I got airborne without a hitch, climbed out and flew for about 45 minutes and CHT temps seemed to be lowering, noted the oil temp seemed to be getting a little hoter than normal so I returned to the field and landed, went into the restraunt for a bowl of soup and when I came out there was oil all over the ground under the nosewheel,
Pulled the upper cowl and it appears the oil cooler has failed and dumped most of the oil. Manually pulled the plane back to the hangar with the help of a fellow pilot from Milwaukee that was looking at my plane I really appreciated his help.
Pulled the lower cowl also and it was full of oil . Looks more and more like a falied oil cooler. Will drain the remaining oil on friday and send a sample in for analysis and then asses the status of the engine.
Will need to pull the plugs and scope the cylinders to make sure they didn't get scored. Then will check the plugs and adjust the valves and torque the heads again as it is at the 10 hour engine time. New oil filter and new oil are in the mix. Will assess the features of a replacement oil cooler and get it on order. Again welcome to the world of Experimental aircraft.
