...I think some of the suggestions would have had dire consequences if you had followed them.....
I wrote this because I feared that others "down the track" could blindly follow some of the advice (without full knowledge of the possible dangers/consequences).
So I wanted to leave a clear warning that following some advice in this thread could easily make matters worse.
And I knew that by typing those words .. I may appear to be putting myself above other advice-givers. But while I didn't want to give that impression ... I still felt compelled to issue the warning.
(If anyone were to search all the stuff I've written ... I'm sure they could find a number of examples of real "poor advice"! )
....I feel a bit sorry for all your ¨civilized guys¨who have to abide by all these rules that contemporary mechanical society has imposed on you.. I actually find myself a better mechanic and more resourceful since I moved to PERU 8 years ago for work ( Aviation Inspector and Mechanic ) -- I know that the welding in the head to try to pull the glow plug may have been a stretch.. but there were alot of crazy ideas tossed out there.. and I had no idea of the users mechanical aptitude..
BUT I will say that I have seen various times now here where a bolt or stud broken down in a hole was removed by painstakingly and slowly ( hours ) built back up to where a nut cold be welded to the top.. and then turned out.. crankshafts.. transmission output shafts.. etc.. etc.. In a continent without easy-outs or broken bolt extractors at every walmart.. I think that the alot of people here with a few mere handtools - could rival alot of SAE master mechanics..
I am super glad the piece came out without any damage.. and I AM SUPER STOKED it came out with a deck screw.. Impressive.. I am going to remember that one for sure-
With ideas like that Rummat81 has a good future down here if he ever has to flee the law!
Crikey! My username is "lostmarbles" and I love unconventional solutions. And we all know New Zealand has more sheep than people so how can it be civilised?
I didn't want to offend anyone (but I accept that if we swapped places ... I would likely have felt I was being slurred).
I saw that you advised putting the rod right into the remnants of the glowplug tip and then flicking the welder switch BRIEFLY so it was clear to me that you knew full well what the risks were.
However my fear is that such "finer points" could be lost on some keen inexperienced do-it-yourselfers (who could even - for example - be using a big welder set on maximum amps).
good natured debate
NOT (of getting me offside with my friends?) ((if that means what i think it means))
the idea of getting it out first is best.
the idea of pushing it in an having the piston crush it into dust works (i know, the first time it happened i s*** bricks but then a long time diesel buddy of mine came over, reached into the cab and cranked over the engine, "done" he said.)
the idea of having the engine crank over while playing with plyers is nuts in my book.
the idea of cranking over the engine to push it out works well but make sure nobody is near the engine bay or in line with it. usually it just pops out and drops right away but i have heard of them taking off.
each to their own, i have heard of guys pulling the head to remove the broken piece of the glow plug.. lot of work, expense and time. for nothing.
cheers and peace
Nah. Wayne's not civilised either.

Nor's Drew/Amaurer for that matter (who I've seen recommend using a BFH for some repairs).
BTW ....I first came across the BFH acronym on MUD and it took me a while to work out what it stood for. It isn't really used much in New Zealand.
Hey. For anyone else compromised by their sheltered location, see if you can work it out from this list:
I'm happy now because I think this thread has everything in perspective (for anyone stumbling on it in the future).
PS. And Rummat81 has proven to be probably better than any of us at assessing risk and coming up with his own ingenious solutions.
