Volunteered to repair a ST2 Lister Air-cooled Diesel, built in mid-1980's. Complaint was leaking from rear crankshaft seal. Looks like it has Fuel in the oil. I removed the valve covers and the side covers, and pressurized the fuel lines but can see no leaks anywhere. Any place else that fuel can get into the crankcase? I also looked at the fuel pump (camshaft operated) and no leak there, either.
Did not run it. But the return lines at the top looks like bird-poop brazing all over. But no visible leaks that I can find there. Possibly when it gets warm it will leak? Am I missing anywhere else? I don't think the high-pressure lines are the leak because if they were, it would miss, I would think.
