I am trying to run an engine without creating an oily mess on my airplane. The method that I am trying is to provide lubrication to the bearings and piston without the excess amounts of oil mixed in the fuel. So far, indications are that my method is feasible. What have I done is fabricated a method to dry sump oil into the crankcase and running the engine on fuel only (NO OIL). I am using gasoline with full power on the glow plug. Maybe later I will mix some methanol with the gasoline to see if I can keep the glo plug lit without power as per the gasseres thread elsewhere in the forum. So far testing has proven that the system works. I have run about a quart of "regular out of the gas pump gasoline" thru an old Saito 45 4S at wot. Teardown and inspection shows no indications of damage or excess wear. There is NO oil out of the exhaust as proven by a Q-tip probe of the exhaust pipe. Further refinement and testing will have to be done before I will attempt to put a modified engine in a plane. Any comments or suggestions would be helpful and welcome.
