Freeze Plug, etc.

Jerry-
Years ago, I found myself in this situation, although I didn't end up
replacing the rear freeze plug until I pulled the engine on my '53 TD.
I was inspired to replace the freeze plugs under the exhuast manifold
when I added antifreeze to the coolant and found that it oozed out around the
freeze plugs and ruined the nice paint on the block. Alas.
The point is that I pulled the manifold, prized out the old plugs as
described, and then discovered that it would be prudent to clean off the rust and
effluvium around the plug seats. A wire brush, and some emery, did the job
nicely, although I doubt that you would have much room on the back TC plug.
Anyway, after the clean-up, I decided that it wouldn't be a bad idea to
smear some Permatex around the perimeter of the new plug before whanging it
home.
An additional reason for this precaution was my use of a Dorman
adjustable plug that was just a scosh oversize (taken care of by chucking it up in an
electric drill and dressing it with a file/emery), just in case.
All that I can report is that the oozing ceased.
I followed the same procedure on my '60 Volvo PV 544 with similar
success, even though the plug on the rear of the head was a real challenge.
