  • rear main seal 62 T Bird

    WE replaced the rear main seal and it continues to leak what have we done wrong

    Sometimes rear main seals are 'finicky'. They need to be done right.
    The factory produced 1,000 FE engines per day without leaks, so it can be successfully done. Re-install following your Shop Manual.

      Are you sure it's the rear main seal and not an oil plug.

          Mickey, I always thought that you only had to offset a neoprene seal, not a rope seal. Seems that would be hard to do with that rope material. Can you clarify how to do this with a rope seal please? I'm about ready to do this job and want to get it right.
          As for the original question, if jack and chris used a neoprene seal, the most common errror is putting the seal in backwards. The seal lip should face forward, toward the engine. That way when oil pressure is present it presses the seal more tightly against the surface to form a tighter seal.
