unfortunetly i dont think that would work , it would be too cold by the time it got their , and the plastic would have no where to go , you would also brake the plug socket as it isnt going to take the stress when hot to undo it.

As extreme as it seems, I would be giving serious consideration to removing the head to sort out this problem.

I would be concerned about any debris left behind finding its way into the combustion chambers in the future.

I would want to closely inspect each plug cavity after the plastic is considered gone to be happy. My view is that this can only be done with confidence when the plugs are removed without ANY chance of particles ending up in the chambers .

Not what you want to hear I know, but desperate times etc etc

Are there any other related jobs that need doing at the same time - water pump, cam belt etc?

Good luck!

Can you not just belt a plug socket on to smash the burnt plastic? Then either suck or blow the debris out before completely removing the plug.

As derts post above. Heat the plug spanner red hot and push it straight down over the plugs.

Another whacky and potentially very dangerous idea:

Put a flammable liquid down the plug holes and set light to it - hoping to either soften or vapourise the plastic...

Watch your eyebrows!

I have to disagree with you here, it is easy to heat up a plug socket next to the head, through the use of a blow torch. With regard to stress in the socket, my old bike ones were just pressed steel tube, they never broke but would bend a tad. the plug sockets either on an extension bar or like CCJ has shown would need to be extremely hot to become stressed. Worst case scenario buy a cheap plug socket which you don't care if it fails.....the other options ?
