Noticed oil on the inside of the plane. Tried to locate source but couldn't. Cleaned everything up and flew around the pattern a couple times and looked again. Still couldn't identify source - oil seemed to be everywhere near the back of the engine. Decided it was the main seal that must be leaking, causing oil to be flung everywhere by the accessory pulley and belt. Removed cabin heat box, pulley and old front seal (engine is mounted backwards in the plane!). Installed a replacement NAPA 14738 seal and test flew for a short trip. Didn't notice any oil but will have to test after a longer flight.
