Coolant Leak Origin?
I don't believe it's a hole, because it doesn't leak constantly or even right away on startup. It's a drip that first appears after 7-8 minutes of idle, and drips a little faster and faster within a few minutes after that.
But then what do I know about it?
Some repair jobs we DON'T wanna know about.

You should use great caution with this type of work. One slip of any jack and you won't ever play the piano again. I think your best bet is to put the front end up on ramps. That eliminates some of danger when you start jacking the engine. When the motor mount is removed, place some type of spacer in there just in case the jack slips. Perhaps a 4 X 4 piece of wood wedged in there.
You must decide if its worth the risk to do the others on that side of the block. Myself, I would wait on the rest. I have had new ones leak because of a sealant failure.

I'll look into that with an internet search.

Man, I find myself doing Risk Assessment taking trips to the john anymore!
Seriously, I'm confident it's kept me outta the hospital/morgue on many occasions. Thanks for those tips my friend.You must decide if its worth the risk to do the others on that side of the block. Myself, I would wait on the rest. I have had new ones leak because of a sealant failure.
I'll definitely inspect the others while under there, and make the decision on them then.

But that end Header Bolt's impossible to wrench off, due to the tall Valve Covers and the A/C Housing.
I came up with this arrangement.
My 1/4" drive ratchet was unavailable and may have worked with the right length extension.
Slow but sure, it came out. Getting it started is gonna be fun.

I love 'em because they run amazingly cool. And you can touch them 10 minutes after shutdown without it having to be Pt. Barrow winter weather either.

Mount itself.
Almost hate to post this! Looks like what I left on a barroom floor in Key West once. Disgusting!

Not much room to work with. I can make a little more room with the jacks.
Got one of these doo-dads, but may not need it if the plug's about to fall out anyway.

Updates to come.

Putting a plug in with that small clearance will be the more difficult task. Good luck. And nice job with the diagnosis.
Learned my lesson. Going with these now.
I'm actually raising the engine, or lowering the frame (however you look at it
). I've found this point to be a safe engine support point.
And this is my usual Frame support point.
So by raising and lowering the two, I've got a little better clearance to work the freeze plug,
As good as it gets, at least without removing the Distributor, Fan Blade or Fan Shroud anyway.

I wouldn't recommend this tool for the answer to pulling freeze plugs.
Good concept, but success depends on a few variable things. Condition of the plug's metal and it's adhesion to the case are two.
Cleaned off the plug .....
..... and after drilling the correct size hole, as stated in the documentation, ....
... the hole strips it's threads, in my case anyway.
Might have to enlarge the hole, but the next thing that comes to mind is to get a slide hammer on it and see what happens.
BTW , all other freeze plugs look good on this, the right hand side.
