Don't be sorry for the story, very interesting!
(sorry do not have windscreen)
But I still don't understand how you got the bolt out after it being red hot. You say unscrewed but how, it was broken off? by the zap machine?
I hope I'll never need it though!

greetings

Hello
will explain,electrode was placed over the broken stud and electrons are fired at the broken stud.This warms up very quick and the heat travels down the stud and frees the threads from the rusty block threads.this can then be unscrewed by a stud extractor,[socket type].
hope this helps explain.

Hi all, a bit surprised at "rusty" head bolt, don't know engine type, but xud's are put in lubed so possibly a result of cylinder head water leak or something more sinister.

Hi Malcolm, I too thank you for explanation (also nice to see the use of the lower case text in your explanation /\ )

BTW how have you got on with the clutch QUADRANT as you not given any updates to that thread ?

Robert, I'd be guessing (But expect its the one he's recently BOUGHT off Chris 'citroenmad') that had the failed HG which may explain your theory ?

.

I would guess the gasket has been leaking into that bolt for a while, so caused corrosion.

Having done a few head gaskets, I've never had a bolt snap, but they do creak a bit as they come out.

I wonder if an ARK welder would have been able to heat the bolt sufficiently to free it?

Have you tried

they normally have lots of spares and quite a lot of XMs as well.

Many thanks for your help.
Quadrant for the clutch cable ,like ever one else still hoping they may come one day.
