rear seal
not hard time consuming. start by removing oil pan, then remove rear main bearing cap , if its a rope seal you put the new rope in and roll it into the cap with something round. push it in the cap real good. then cut the rope about a 1/16 longer on both sides. then tuck it down into the cap. then pull seal out of block. there is a tool for inserting it. your parts house would have it. its a handle with a cable that looks like a Chinese finger trap. pull it in, then cut the ends long and tuck them in. reassemble .rubber seal just slide in. i almost forgot soak the rope in oil first
