Broken glow plug.

Hi folks.
3 of my glow plugs are dead in my 04 so i managed to get 3 out including a working one and then snapped the plug in the port.
I managed to drill it and started threading it with a 4 mm tap and bang the tap snapped so now i cant attempt to drill it and pull it out.
The main threaded part is out its just the tip thats lodged.
Someone said push it in and retrieve with a magnet via the injector port but i am not confident about that.
I guess i might be away to look up a head removal video??
Any advice is welcome thanks.

First I'd tap it right though, in to the chamber, then recover it through the injector hole as suggested. Make sure the injector comes out first and set that piston down the bore far enough so it doesn't get damaged. I have a magnet on a flexible shaft for recovering such things from unacceptable places.

Could you remove the injector, drop the piston to BDC, injector back on, use the starter motor to pop the tip out?

With risk of serious damage - I wouldn't !!!!!

Thanks guys.
Been at it for hour with a tiny magnet i have in the garage but no luck.
Fairly gutted as i was so close to getting it done (decoked everything and blanked egr)
Looks like a garage job

How far have you got?

The tip is sitting on top of the piston pak and i spent 3 hours trying different magnets and wire etc to try and fish it out.
Resorted to beer and whiskey whih is helping

I have one of these. https://www.eurocarparts.com/ecp/p/tools/hand-tools/general-tools1/precision-tool/553774510&0&t5_215&type=shopping&gclid=CjwKCAjwh9_bBRA_EiwApObaOOcjGv-f0rc4kR5B9-Mov1H8WcVCRMNgI8CRr_2Ae4dqZrsWkakR7RoCSJYQAvD_BwE

It makes grabbing things in the combustion chamber easy.

Grease on end of suitable stick?? Air line? Seal hole to a pipe and apply vacuum cleaner? Just thinking out loud!!!

Thanks guys but i only have a 6mm hole to work with so neither will fit.
Its looking like a head off job for someone as I aint got time to do it

I'd persevere for a bit longer as removing the head on a TD4 is a right old game.
You'll need to get creative.

Let someone else have a go at getting it before deciding that the head has to come off.
Sometimes your frustration can get in the way

Thought you'd taken an injector out? Bigger hole?

I have but i am having no luck so far.
Tried compressed air, hoover and magnets with no luck.
7mm injectir hole is a bit ticht.
Silly question but whats the best way of manually turning the engine by hand as i want to try with the piston at different heights cheers.

22mm socket on crank pulley bolt.

Many thanks Andy.

Where are you? I have a 6mm camera on flexi with magnet attachment. Even if you bought one at about £70 it is cheaper than head off!!!

Many thanks pal.
I am in westhill and think i will have a look at a camera as this is just not happenimg blinda day and a half and starting to get a short tempered lol.
Thanks

Hello again Andy.
Thanks for the offer
Having a break and then one more go with the hoover then its back to work tomorriw and forget about if for a few days.
I bought the motor with the intention of fishing and shooting and not spending much on it so will see if i can get someone in Aberdeenshire to do a head off homer as i am not experienced with cams, chains etc.
I am liable to bugger that up too lol.
Begs the question why dont manufacturers make larger bodied glow plugs to combat this constant hassle people have removing the noodly little sh!ts of things.
Regards

I have a 6mm diameter camera (about £8 from eBay) that does fit in the glow plug hole. It plugs into my phone to give me instead visibility inside holes and stuff.
I also have a 4 claw grabbing device which does fit in the injector hole. With this combination of tools I have recovered broken glow plug tips and a spark plug electrode from engines.
