1923 Jordan rear main seal leak

1923 Jordan, Continental Special Vertical L-Head, 245.6 cu inch,  leak at rear seal on Continental engine crankshaft
 I learned some Continental 6-cylinder engines of the 1922 - 1924 era do not have a rear oil seal, but have a flanged crankshaft that throws oil forward into the oil pan. I think my engine is a Continental Special Vertical L-Head, 245.6 cu inch. I read that on these engines, the cap is not slotted, and there no way to attach an "O", a gasket, or rope seal. How can we fix the rear main seal leak? Were there any updates to this system?
