Are you serious??????
How the fook do you think you could get all the remains of the glow plug out with anything other than taking the head off ???
Have you asked all the posters who suggested useing magnets and Blu Tack the same question.
I have taken heads off all sorts of engines and its by far easier and cheaper than just taking a chance.
I suppose you sceptics would take a chance with leaking brakes aswell would ya?
As far as the red letters go I dont think they were big enough.
I feel sure if you read my replies on this one you'll find that I do say 'taking the head off is the best bet' BUT if the broken tip is STUCK in the head, engine compression MAY just blow it out.
I'd assumed that the original poster had checked to see if the broken tip was actually stuck in the head, if it is (as I suspect) stuck in the head no bloody magnet on Earth will shift it.
Stay cool.
