Clean it out, fill the core pug with JB weld until you need to take the engine out or head off for another reason, been there done this.

About 25cm straight back from the failed plug.
I've read of others using epoxy, but yet others saying it should only be considered a 'get you home' repair. Thoughts?

25 CMS?
Could do that in situ I would have thought.
Have you done one before?

Nope. Never. Only just found out what those recesses were after that little fountain appeared.
From what I've read the technique is:
- Drain coolant.
- Stab a screwdriver through the middle and prise the cap out.
- Clean up mating face in the block with emery.
- Hylomar the mating faces
- Insert new plug using (ideally) a socket the same diameter as the plug's OD and tap gently home.

Nope, that's it.
As said 25cm clearance I would do that in situ, I have an old shaping chisel that I drive into the side of the core plug then use it as a lever to pop the plug out, some people use self tappers then lever the plug out, others drive them inwards then turn them sideways to extract them.
Bet there are some vids on youtube?

Red hylomar is best.
Got blue. Is that ok?
