Originally there was no seal in the rear main. The seal that the vendors sell are modern "fixes" for leakers that don't work. I have found engines that have had ropes installed in the grooves that never work and leak. Never seen a rope seal or rubber seal or a cork seal that worked for any length of time. Ford knew best.
