glow plug sheered in head, advice on my plans

one had to sheer off and had to be last one.

should i heat engine up to expand it, tap or die it to thread the hole and get a bolt in there, let it cool around bolt and try to extract

or thread it in cold, glue a bolt in there and warm engine to expand and try to extract.

ideas?

It will be ok the way it is as I believe the td4 doesn't rely on them unless really cold but I know a man at Carlisle that can come to you and extract it properly for £75 plus travel look up extract engineering hope this helps

you need an extractor set like this one someone who has one

^^^^^stahwile make them!

Just had new injectors fitted, talking to the guys at Kent injections who done my work,
They said the td4 dose not need glow plugs because its direct injection.
They are fitted for extreme weather conditions that we dont get in the uk.

on very cold days ..
rekon they would save on starter motor wear 'n tear ..
not to mention .. not potentially filling the street with a pall of white acrid smoke

mine is the first diesel vehicle i've driven that has working glow-plugs
most previous ones had them but they didn't work .. 'n that were in the upper states
of north america .. on rare occasions .. well below freezing temps .. weak battery ..
ether spray was used ( easy-start ) to get them to fire up ..
usually it were lots of cranking .. then shudder splutter into life ..
and mountainous volumes of white stinging-the-eyes smoke
and then .. the engine weren't shut down until the trip were finished
( long haul artic-hgv rigs .. 'n not common rail type engines )

get it pulled out ,get a hole drilled in and an extractor which has a reverse thread then get some heat onto it then as it is red hot spray with wd at this point be careful of any flames, then wind the extractor in then jobs a good un

I wouldnt even bother - it will be fine with three, even on the coldest of mornings.

Unless you snap the extractor which many people do and that opens up a whole new world of pain and expense ( due to how hard they are making them all but impossible to drill out).
If you really must remove it try heat (lots, not as in ridiculously high temp more as in often and thoroughly) penetrating fluid ( lots also) and a left hand drill.
Easyouts have their place but then again so do high explosives and I wouldn't recommend either for removing a glowplug ( I might use one for it but I wouldn't recommend one to anybody else )

the way I do it has never failed me the last one was a spark plug in the wife's freelander but I think I went over board when I said red hot but get as hot as you can then putting something like wd on it will cool it down quick and usually frees the bit of tension on the part.

think i'll leave it , starting better on three new ones than four old ones lol, if becomes a pain will get garage to extract. got a mate with 4x4 garage. thanks for all advice
