Hi all.
I'm after some advice/guidance please. Im changing glow plugs at the minute on 1.9cdti 150. The tip of the plug has snapped off and is stuck in the head! Can I get to it by removing the injector for that cylinder or do I need to take it apart.?
TIA

There are some garages that have specialised equipment to use & try a removal of broken glow plugs , however if that out come isn't favourable then removal of head is needed .

I have one to remove soon too and this is the nightmare scenario I'm dreading.
Did you soak it in plus-gas / WD for a good few days before and try to remove while was engine warm? Some say give them a 16th turn tightening first to try and break the torque. I think they're only supposed to go in at around 8 - 10 Nm, but depends if someone else changed them before with big man hands and no torque wrench.
At least you have use of the vehicle in the meantime. I guess that particular GP was already goosed anyway?
I'd insulate the end of its' power lead and tuck it out of the way for now before it shorts against something.

They corrode in the head and seize up, that's why they end up tight. They are usually quite tight all the way out.

If you've snapped one in there then best get a specialist out. It's that common a thing there are mobile companies that only do just this along with seized injectors

I didn't do any of that tbh.
The glow plug came loose pretty easy, it was the tip that's snapped off and is still in there.
I'm taking it to the local garage to sort out now tho. Hopefully they have the kit and know how.
I've just done a re-gen on it aswell! It was on 96% before, its down to 73% now. I thought it would have been a

soak them in Plusgas for up to a week before and you should have no issues removing them.( little bit late now I know)
That stuff is brilliant for jobs like this.
I used it on the turbo manifold studs/nuts on my Z20LET after being on for 115k and none snapped and some are prone to snapping

Well, topped mine up with 'anti-swearing fluid' for the last time last night. Just went out to have a go and it came out a treat after tightening it up about a 16th of a turn first, then worked it slowly back and forth when it seemed to stiffen up any.
Relieved.
I checked its' resistance on the bench afterwards and it read about 400 Ohms, whereas when on the car it read several hundred k Ohms when measured between the tip and the battery -ve. It was definitely the duffer though - the rest were 0, or virtually 0 Ohms.
