Showing my age here- On a rope type seal, you would cut short pieces and force them in on each side of the rear main in the block, and pack in all new rope on the cap. Trying to snake that old rope out and new rope in was a guarantee that the vehicle will be back. I did some of those in the '60s and '70s, but haven't seen anything like that since '84, when I graduated uni, left my mechanic job and went to work as an engineer.
