I just did my first oil change and wanted to share my findings. When I removed the drain plug I looked at the oil pan to remove the plug gasket and non was there. I found the aluminum gasket painted on the plug. The pan was pained with plug in place. I had to use a sharp knife and insert it between the plug and gasket and give the knife a sharp wack with a piece of wood to remove it. I can only wonder how many engines have two gaskets running around. Just a thought. Ed
