Before you sell it are you sure it is a rear main leak? My Town Sedan had a leak and I was about to pull the pan. But first I installed a bottle of fluorescent dye and checked with a UV light.

After running the engine I could follow the 'glow' back to the oil return pipe. Saved me from pulling the pan.

On another engine I checked it was obvious that it was the rear main. The inside of the flywheel 'glowed'.

Hope this helps and good luck.
