Hi All,
looking for some help. Been getting my butt kicked by the rear main seal on my 78 200 six.
The engine leaked oil. I decided to change the pan gasket and rear main, while I had the trans out to fix the clutch.
Installed per the regular wisdom and the advice of my dad, a 25 year Ford mechanic. Since the engine sat for quite a while before running, I thought maybe the rear main seal had somehow flattened?
Put in in a new rear main seal and this happened:

Of course this leaked.
I was afraid I put in the seal too agressively and scuffed it. So I dropped the pan again and put in another seal. This time I loosened all the main caps. The seal went in perfectly. I rotated slightly so the seal ends weren't lined up with the cap/block and applied a VERY small mount of forma gasket to the ends. After torquing all the caps, the seal was in there snug. Put it back together, ran once, no problem... now it's leaking again. I'm pretty sure it'll be rotated again.
Have you seen this?
I'm not putting any adhesive or rtv or anything on the seals. The seal on the rear cap is LOOSE. it'll fall out if I don't hold it. The pin from the rope seal many moons ago is gone.
What am I missing!? This is really starting to make me angry!
