Decided after much not starting my 2.2dti needs new glow plugs "here goes another simple job made impossible" I thought. So I had a look anyway, it looks incredibly simple. It can't be. A whole plastic cover and they're there looking at me on the left side (looking from standing at the front). I'm amazed. It can't be so simple!
(You may have guessed me and this car aren't the best of friends at the moment)
-
Get the engine good and hot before trying to remove them and go easy on them,its not unknown for them to snap upon removal :y
-
Yeah I know they can be a pain for that in general but o meant in terms of access, other "simple" jobs are a pain. Like the fuel filter. I'm considering so that while I'm at it. Who knows why they put it there :(
I take it the glow plugs aren't particularly bad in an omega, you just meant plugs in general...? (I hope)

It seems to be the long thin fine threaded plugs that a lot of car makers seem to use these days :-\
-
Enter TB. He seems to have issues with glow plugs ::)
-
Hell fire they are long! Must picked them up. On way home and doing them now. Engine should be nice and warm from the 50 miles I've just driven from work, to auto factors and home. Size might explain the cost. £35!!? Ones I got for my 405 were £20
-
Right here goes nothing. Wish me luck! :-X
-
Best of luck! Big bar and smoothness is much better than short bar and brute force :y
-
You know what's even better? If my 10mm deep socket hadn't grown legs. Can't find it anywhere no idea why it's not in my toolbox. I've got a stronger battery in for now. Take 2 tomorrow.....
(I think the car stole the socket to annoy me!)
-
Well, I'm shocked. After going out and buying a socket (i got loads of different sizes ready for another going walkies lol) it took me all of 5 minutes to do them. None were stiff, and only burnt my hands on the turbo once. By far the easiest plugs I've ever done.
Bit of a concern, plug number 2 (counting from the front of the engine, opposite he gearbox end) is wet. I've had the car running for about an hour while I dropped my brother off and picked up bits and bobs, so if it's just a duff plug, I would've expected the heat of combustion to have dried it off. The other 3 are fine, just the usual sooty build up you'd expect. This isn't sign of head gasket is it? Car runs fine and doesn't smoke. Only smoke it gets is white smoke from unburnt fuel when it doesn't want to start from cold. Other than that all is well
-
Was it wet with water or diesel :-\
-
Oops thought I'd said. It seems to be oil. Stains fingers like oil does, doesn't smell like diesel, don't lose coolant (well not since that auxiliary heater thingy miraculously fixed itself lol)
-
Was the seal intact on that plug when you removed it?
-
What seal?
-
Presumably there is a seal of some description between the head and the glow plug :-\
Unless the camcover gasket is starting to weep... not too many places to get oil onto a glow plug :-\
-
The threads seal it
-
Out of curiosity though.. If you have radweld or equivalent in the system which then subsequently blocks the matrix so virtually no heat would flushing matrix out dilute the radweld and start the water leak again?
-
The threads seal it
Ok :y camcover gasket it is then... worth checking the breathers too :-\
Actually scratch that... do you mean the cylinder end?
-
Got a few things going on here, I'm starting to loose track lol. It's not the matrix that leaked, the little pre heater thingy behind the right fog light was weeping but when I started using the car again, for some reason it's stopped and doesn't need topping up. Anyway the point is I know water isn't getting through the gasket.
The glow plugs don't have seals. They seal themselves on the thread. There's no rubber or anything to seal them in. I've never actually known one to, there weren't any on the old ones, new ones didn't come with any.
The cylinder that had the wet plug was (working from the front of the engine) the 2nd one. Also o can't see how the cam cover gasket can cause oil to get onto the plugs ie into the cylinders. Wouldn't it only be possible via either head gasket or piston ring? But it can't travel up the chamber from the piston ring without being enough oil to cause other issues.
Or, can this be normal?
-
Leaky injector perhaps... mixed with soot, might seem oil like :-\
-
Wouldn't that only be evident if it had been stood? I had it running for an hour green did the plugs immediately (hence burning my hands lol)
-
A wet glowplug is usually because it's knackered,the ones that work glow to red heat which cleans them up,so long as there are no other issues such as oil consumption or coolant loss I wouldn't worry
-
Well just been out. Engine was cold, glow plug lift came on, moment of truth. Made no bloody difference whatsoever. Battery is still weak as not had a chance to charge it properly, but to be honest I'm just clutching at straws. I'm getting sick of this bloody thing.
-
Dti needs a fully charged battery in this cold weather,fully charge it up and then try starting it.
-
Only charger I've got is the alternator lol
