Thank you for your reply I appreciate your timeIf you have a 292 you can probably stop or at least slow the leaking to a great extent. If you have a 312, you have a problem. The engines use a different seal configuration. I have seen a number of possible rear main seal fixes for 312 seals.; Modern rubber seal, adapted Jaguar seal, adapted Chrysler seal, and a couple of others that I don't remeber at this time. Pretty much all of the "fixes" do not stop the leaks in the long term. I suggest you join the national club, Classic Thunderbird Club International and also one of their local chapters.
Good luck to you, John
Thank youIf you search the forum there was a thread titled as below. Someone responded with an attached an awesome repair article and they mention the allowed amount of play forward/backwards the crankshaft should have. I've never had a car with a Y block but I would take a stab that maybe it would be worth looking into? Especially if you're going to take it apart again.
