First off let me commend you for asking for the assistance of your IA or AP mechanic. I'm sure they will be happy to show you the ropes so that you can perform ';legal'; owner maintenance on your own with competence. There are many things you as the owner of your aircraft can legally do to insure the continued airworthiness of your airplane. The hands on work will make you a better informed and safer pilot.





The J3 is pretty basic, you may want to do some uncowling and examine the engine for leaks and general condition at the time of oil change. It is best to run the engine shortly before beginning the work to bring the oil up to temperature and suspend any particles in the oil. There is a drain at the lowest point of the oil sump, this will be removed and replaced after the oil has been drained. This plug may also be safetied to prevent it from becoming loose and falling out during operation.





You may want to sift the oil through a fine mesh cloth or paint strainer to see if any debris is present. You will clean and inspect the oil screen as well. Refill the engine with the proper specified oil in the proper quantity and note in the log book for the engine the work that was performed along with the date and tach time of the aircraft.





Ground run and inspect for leaks then test fly and return to service.





Have a great day flying that classic!
