Hello,
despite being very cautious it seems that 2 of my glow plugs might be broken I sprayed wd40 a week prior to remove the plug, I warmed up the engine, I used a torque wrench set on 20NM 2 came out very easily but 2 other wont pull out, they dont look broken, the tread is out but they wont pull out. they dont rotate easily, I still need to use the wrench to rotate them the core looks it is still attached to the outside body, I used a open wrench to check if the core was rotating simultenously when I was unscrewing the body can it be the plug is still in 1 piece but the hole is just narrow and some gunk preventing me to pull the plug? what are my options now? thank you in advance Fred  Click image to enlarge |

Normally it’s burnt carbon deposits on them that stops them coming out. The trick is to be able to pull enough, and hard enough, without them breaking. That your time would be my advice.

Lots more penetrating fluid and lots of turning with gentle pulling pressure

One of the indies I know has a trick for this: prior to any work being done on injectors/glow plugs, he gets the customer to drive around for a few days with some 2-stroke oil in the tank.
that way, the injectors/glow plugs come out more easily -- 2010 Defender Puma 90 + BAS remap + Alive IC + Slickshift + Ashcroft ATB rear 2015 Range Rover Sport V8 Supercharged

Always run mine with 2 stroke oil in the tank.
