I'm guessing you can get the old freeze plug out with a long drift and pair=
of right-angle pliers. Installing the new plug, though... 10" isn't much =
room to swing a hammer to drive in a new plug with a socket. Hard to hit it=
square with any force. Maybe make a press with two plates and a piece of =
all thread? Push against the firewall to press the plug into place?
There are rubber freeze plugs with a hex nut that turns to expand the plug =
to fill the hole.
Good luck with the repair.

Subject: [TR] TR Head Freeze Plug
So I have a 1953 Morgan with an original Standard Vanguard engine. The=
engine is very similar to a TR3 engine. It recently blew a head gasket and=
overheated. I had the head resurfaced and bolted it all back together, sta=
rted it up and discovered that the freeze plug at the back of the head is l=
eaking now. Dang! Wish that I had thought about that before reassembling...=
On the Morgan the freeze plug is about 10" away from the firewall and not =
as close as it is on a TR3. I do not want to pull the head again. Any known=
tricks on how to get the old plug out and the new plug in without removing=
the head?
