Then pour the cement in.
They usually fill either half or the entire block, often running no cooling water at all, or only through the cylinder head.
So not sure how suitable it might be...again it's back to the temporary thing. But filling from the inside should be a lot better than epoxy from the outside if it can be done.

In your case though you'd only be wanting to fill the dodgy area itself, not the entire block really.
sounds like a plan if the plug the hole fails. ive just got in for lunch, and ive realised now how the oily water mix has got in the radiator.
the engine holds 4 gallons of oil, when we drained it there was 12 gallons of oily water mix in the sump, it was like grey paint !
so ive looked at where the hole is and with 12 gallons in there the oil level will of been in the bottom of the bores
it also explains why it wouldn't idle as there was resistance there from the sludge under the pistons I think, as soon as we drained the coolant and changed the oil it ran perfectly.
I ran it for a few seconds with no coolant in to position it in the workshop and it ran absolutely perfectly hence I don't want to strip it, just plug the hole if possible, fingers crossed theres enough thickness there to tap a thread and plug the hole......
