I'm new to this forum, and I've got this problem and have done the forum searches - have found some excellent threads and information. Have learned this was a common problem on Mac 10 series and some of SP's. My question, and the embarrassing part: When I pulled the oil tank front screw and cover off I was pretty careful. It had a single screw holding the automatic oil pump on, so loosened it up and the pump came right out. I got to cleaning and inspecting parts of it, then happened to look back in the oil tank. There was a black disk about 5/8" diameter, maybe 3/32" thick, with a small hole in the middle and a little pin protruding from the flat surface. I need to get a picture. I've got no idea and can't figure out where this goes, what it does, or anything!! I fix up vintage sewing machines, and this has me stumped. Anyone able to tell me what it is and where it goes?? Thanks. I think I've got a handle on what to do about the leak, based on the great info here.
