Tracy--
Though I have never blown a freeze plug on either of my Healeys I have blown
several on the MGA race engine in my Elva Courier. Luckily they were ones
on the side of the block and I was able to access them--the one on the rear
of the block is inaccessible due to its proximity to the firewall.
In light of my experience I now use the Dorman plugs whenever I rebuild an
engine. I clean the recess down to fresh metal and set the plugs in a
fast-drying two part epoxy and have had no problems since I started doing
this. BTW I have experimented with trying to tap the hole for pipe thread
so that I could use a screw-in plug but could not find a tap that would get
a bite on the shoulder.
