For discussion - possible method to remove glowplugs
I'm just throwing this out there for discussion, I don't know how relevant it will be, whether it would work in this case or if it would destroy the cylinder head.
I subscribe to a YouTube channel by a Canadian guy calls AvE. He's quite funny, but most of his videos are thought provoking as well as entertaining.
Anyway, yesterday he posted a new offering about removing broken steel studs from aluminium heads. I won't put a link up on here as there is a bit of swearing in the video, but just go to YouTube and search for "AvE remove broken studs" and you'll find it. This video shows him using Alum to precipitate an electrochemical reaction, dissolving the steel stud out of an aluminium block.
I just wondered if the same principle could be used to loosen glowplugs which refuse to budge or even remove broken ones?

Had a look on Internet at this and it looks legit. Where would the dissolved glow plug go though, into the cylinder?

Step two... realise that step one will not work and see if you can come up with a way around it.
Perhaps find some way to make an aqueous gel solution of alum?There are two rules for success,

That's why I threw it up for discussion - I don't know whether it's just a stoopid idea or it may just be the germ of a good one.There are two rules for success,

Definitely has utility, needs refining though.

I guess it could work if the heads were removed first, although that does seem like an awful lot of work.
There was a thread recently where somebody had successfully removed all six glow plugs by using a powered impact driver with the torque set to just below the installation torque. 9nm against 10nm or something similar. Took a bit of time but was otherwise drama free, IIRC.Darren

I also think it may have potential after some refining. However, I wouldn't be trying to dissolve the whole glow plug, just loosen it up enough to extract?
Working in the marine environment we often come up against the situation of a steel (mild or stainless) fitting/bolt being bonded with aluminium after time - not an ideal mix. One method that can work is to soak with Tabasco sauce overnight - honest injun!Currently 2009 Disco 3 SE, 2013 MY D4 HSE and 2016 D4 SE
