[TR] TR Head Freeze Plug

[Cliff Hansen]

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, started it up and discovered that the freeze plug at the back of the head is leaking 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?
     TIA,
