During a recent oil change on my 0-360 A1D, I removed the shorter and damaged oil sump screen on the left in the first photo. The replacement screen came today and it is about an inch longer. This is the horizontal screen on the lower rear of the engine sump. I have seen Aviat parts manuals that show a plug used with the screen. Does anyone know the history here? Was the plug eliminated and the screen lengthened?
