Gents,

Are these the correct glow plugs for my car? Mine apparently have gone tits up.

yep those are the ones

 

[nwjobs]

Thanks!

Is the glow plug swap pretty straight forward? Is there anything I should know before jumping in, or is it just a quick pull and swap?

 

[79Mercy]

Yeah its easy, sometimes you might have some carbon build up which makes it hard to pull the plug out but just keep spinning it and it will come out after a bit.

Why pay a bit more when you can get them here?

Your Parts Search Returned 2 Part(s)

$8.59 each for the 240D means that's $33.xx and you still get a few $$ worth to spend for other bits you need, to get free shipping of $50 and above.

Thanks MBeige. I'm sure I can use the remainder on something else that's wrong with the car

This is probably the first time I've heard of glow plugs having tits

hahahah, I guess there is a first for everything.

The Service Manual recommends reaming the carbon deposits out of the Glow plug Holes.

There is a Glow plug Reamer (tool) for this. Or you can find an alternative way to do it.

I put the new glow plugs in today. I didn't do all the reaming, etc. I've read more horror stories than good from the reaming.

I discovered a spot of wet oil on one of the plugs. My guess is this can't be "good oil." Am I right? There shouldn't be oil on any of the glow plugs right?

That reamer is expensive, I ran a stiff brush around in the holes.

 

[nwjobs]

What about there being oil on one of the glow plugs. Can someone comment if that's an issue, if why it is.

 

[300Dman]

The assumption is that you are burning only Diesel Fuel.

If it is actually Oil the only place it can come from is the Engine. Piston Ring issues or possibly Valve Stem Seals and Valve Stem clearance issues.

If they are wet from Diesel Fuel it could be Injectors that are worn and not atomizing well or something that interferes with the Fuel Burning correctly like Timing off and poor compression.
Not enough Air due to Plugged Air Filter.

 

[300Dman]

What horror stories have you read concering Reaming out the Glow Plug Holes?

 

[nwjobs]

Horror stories include the engine popping and running horribly after a good reaming. I guess a little oil isn't as bas as I first suspected. Does anyone know where you can buy an engine rebuild kit?
