Here I go again... Looks like I'm missing another small part from my Thames project. I've got a bit of a leak around my oil pan (sump) drain plug and looking at the parts diagram it appears there should be some type of washer on the plug. I don't have that. (I must have stirred things up when I did a bit of an engine flush, removed the old sludge and put in new oil.) Anybody know what material that washer is made of so that I can make something up or look for something at the hardware or auto parts store? Thin copper maybe? Thanks.
