It goes without saying that you should coat the edges with a good epoxy before
you bonk it.

Jack,
The old freeze plug was found last night under my catch tank at the battery
tray. It didn't have much of a ding in it
so I suspect it could have been flattened more/better when it was first put in.
Last night I was able to clear stuff as required to drill a 1/2" hole in the
firewall directly behind the plug.
I already have a length of 1/2" solid round bar, tapered/rounded at the end in
the hole just waiting for the new plug to arrive.
The round bar runs right under the dash. I'll be able to knock it in from the
cockpit with a 3 pounder.
The car was running better than ever when it went, compression is at 200 psi on
all four so at the moment
I don't have any reason to believe there are other problems. No evidence at all
of water in the oil or cylinders.
However, once the plug is replaced and running again there will be detailed
inspections once it's back up to running temp.

Hi Jim. Consider this. Pulling the head may give you the most correct fit,
and also may be quicker, all things considered. When I was racing, and had to
pull the head at the race track, I could get it off and back on, new head
gasket, and nuts torqued, in under an hour. By the time you make clearance
under the dash, and drive the plug in, possibly not aligned correctly, I'll bet
you will have over an hour invested. Good luck.
Jack
PS. have you determined what caused the freeze plug to blow out? The one
time I had that happen at the race track, it was the result of a major cylinder
head failure. You may be looking at a bigger problem than just the freeze plug.

Duncan,
I think that?s where I?m going next, the freeze plug is just about in line
with
the bottom of the dash or close. The good thing is it blew the old plug
completely out.
I just need to knock a new one in.
I?m pretty sure I can go under the dash and through with a piece of ? or
even ?? round
bar about 2? long which I can scrounge at work.
I?ll have to remove some stuff but still better than pulling the head.

Can you drill a hole through the firewall and drive it out or yank it out
that way?

I was wondering if anyone has a clever method of putting in a cylinder
head freeze plug without removing the head.
I was instructing at our drivers school this past weekend when it blew
out.
I may have enough room between the firewall to use a short blunt air
chisel
but I have my doubts so if anyone has a better one please let me know.
Thanks as always,
jim g
