MG Midget and Sprite Technical - spark plug threads n helicoils

My 77 midget has helicoils fitted as plugs have obviously been overtightened in the past. .. .

When i recently removed the plugs on eof them came out with the helicoil attached to the plug. . . .

I am damned if i can get a replacement helicoil back in and am worried i might make the thread problem worse. . . . any advice/tips?

Yeah.... Common, I had to do a helicoil on my old mazda truck, it came out everytime I pulled the plug, I just reapplied the glue amd stuck tje old heli back in and re inserted the plug, gettimg the plug off the heli was the worse as the glue attaches the heli to the plug...

Piece of copper around the heli in a vise bench, and a big soscket wrench and a little heat will sepwrate the heli from the plug threads
