[TR] Aluminum Head Plug

[terryrs at comcast.net]

Thank you to everyone who replied regarding the leaking aluminum plug on top of the head of my TR3A.

Especially thanks to those with the advice about a 3/4 inch plumbers plug.  I needed to source a 3/4 inch pipe thread tap from Amazon.  After carefully cleaning the threads in the plug hole, I put some sealant tape on a bronze plumbers plug, which has a square head that grips nicely with a 5/8ths wrench.  Tightened to the max max.  (Not enough room there to use the big Crescent I used to tap with.)  Filled the radiator with coolant and the seal is holding strong.
