It is a used Lycoming O-320 E2D, that has been converted to a D3G, which means an upgrade from 150 to 160 HP. I degreased it and cleaned it. I filled it up with 4 gallons of Shell anti rust oil, which is a preservation oil, since I am not going to use it for a while. I also added 4 dehydrators in order to check for moisture inside the engine.
