Or any model that uses oil line block #503854801 that seals the pump to the case..
Regular gasket material by the roll from the parts store works well. It's thick enough to give it the extra pressure but not too thick to throw it out of place..

Cut a piece that matches the bottom of the area in the case so that it fits down in there with no space around the edges..

It'll look like this when traced out on paper.
I ran it and tuned the low with the bar off so the oil was pumping out pretty good. When I shut the saw off I set it down on this piece of paper in the pic for 12 hours and it didn't leak.
Here's another pic after cutting wood. It sat over night and then in front of a heater for a couple hours before I took the pic.

You'll also want to pound out the entire flat part of the metal plate if it's warped up and bent out of shape.
