I have found that I have had plugs break at 30Nm with the vibro gun.

2006 Discovery 3 TDV6 Base 5 Seat Manual Tonga Green

For what it's worth I contacted Laser to ask about what effects an airline with under 80PSI pressure (recommended min) would have, and received this reply:

Hello Andrew,

You are correct in that the lower the input pressure equals the output torque.

I believe this tool will give you the best chance in removing a glow plugs that could be stuck in by corrosion or carbon build up.

We have not known anyone to break a glow plug with this tool on 4 but it is possible if the corrosion on the plug is bad.

I personally found it best on 4 and once the plug starts to unwind go forward and backward so the impact vibration works on the cause until its removed.

Then obviously the glow plug aperture needs vacuuming and preparing ready for the new plugs.

We cannot guarantee this tool will remove all plugs or even damage plugs but it will be your best option I believe.

Kind regards

Well good to read that writing this 'how to' does encourage people to take on the job

Would be interesting to learn why some have a lot of carbon deposits on the glow plugs and some not. Is it the quality of the diesel? The ones I removed were only ever so slightly corroded at the top, so near the part that is visible outside the cylinder heads. 2nd and third thread from the top. On the piston side they were all pretty clean.

Here in Norway we use winter diesel almost 6 months a year and pre-heat the engine with the webasto before starting. But I hear about breaking glow plugs as well so not sure.

The carbon usually builds up along the length of the glowplug (and they are long) and they aren't perfectly straight.

So when you go to turn them, they hit carbon and go tight.

Glødepluggverktøy

Hei.
Ser du har gjort jobben med å bytte glødeplugger, og at du kjøpte verktøy til dette. Hadde det vært mulig å leie det verktøyet av deg?
Mvh

Just started glow plugs and havent got the vibro tool. Done glow plugs before on other vehicles without. So i was exceptionally careful. Despite this being ever so careful going back and forth etc, penetrating oil and heating a small socket up to sit over the plugs ive still broken 5 of the 6 plugs. They all nudged with a little click so just kept going both ways and still bust. Only one is out but still coked in.

Either get the tool or tackle these way before they’ve been in 19 years!
