I posted this a while ago, but can't find it now.

This is the way I remove glowplugs and have recently done 2 engines with 7 out of 8 being successful!

The last one came out fine with the torque wrench approach and unscrewed leaving the tip of the plug stuck in the head.

The electrode came out with the plug hence no resistance to feel at all as the plug came apart and I couldn't tell it had disassembled itself !

What to do.

I considered taking the injector out and dropping that piston to lowest point and punching it into the cylinder then picking it up with a magnetic tool. Only the very tip is magnetic and trying it on an old one showed this could be very tricky. My mini magnet tool which lifts 100g easily if all magnetic only just held a glow plug tip.

So, as there was a hole in the remaining part where the electrode went, I found a 2 inch long thin self tapping screw. Put a washer under the head so that it couldn't fall in the glowplug hole and screwed it in tight.

Dropped that piston to lowest point. Removed injector or the tip of the plug will hit it.
Tapped the screw head until the tip moved in to break the carbon seal and then it went loose and screw plus tip could be removed with fingers !!!

Just a share if the worst happens when you do it.

The tip can be seen down the injector hole and does foul this access if it protrudes so ensure there is nothing there when you do it.
