Re: [MBZ] GP Install - 91 300D 2.5T
removing the intake is the easiest way of doing it.

Re: [MBZ] GP Install - 91 300D 2.5T
I haven't checked them - because it;s easier to replace them than check them
;-) but the dash light still works fine. I do have a cold running
problem - but it;s getting better with driving.
And, I'm in no hurry to replace them - just preparing myself -

larry, are you certain that any of the plugs are bad? they're not really
a
maintenance item unless you're in a cold clime, and i wouldn't replace
them
until the dash light stops working. Then replace all 5.
BTW, I agree - on my 123, they were a snap to replace (one 12mm
ratcheting
wrench later). the 124 plugs look like a bear.

Re: [MBZ] GP Install - 91 300D 2.5T
Does anyone know what the symptoms are for one bad glow plug out of five? Harder starting. A dash light that doesn't act right. Do they go bad gradually or do they just wake up dead one morning? They stroke out. After all, they're a cousin to an incandescent light bulb. One day they're fine; the next, not. -- Jim
Re: [MBZ] GP Install - 91 300D 2.5T
Thanks Marshall - I'm planning t change them because I have 104k on them -
plus I have cold running problem I'm mentioned here - ahd you suggested it's
possibly carbon build up which needs driving long distances to cure - which
it;s getting. My wife drives it every day to work - 100 miles RT at 70mph.
With Summer here it should clean itself out more quickly.
Thanks to all -- I'll replace the GPs when I feel like punishing myself. ;-\

I don't understand the question. When a plug goes bad the resistance
usually increase some to a lot.
A set of glow plugs in an engine that has after start glow function
doesn't last as long as they do in older cars. 90-150kmi would be good
life for an engine with 15-30 second after glow. The later engines with
up to 180 second after glow are likely to fail after 60-100kmi depending
on how many miles per cold start.
If you think the plugs are all original and you have more than 100kmi on
them, I'd CHANGE them all and keep the good ones as spares.

Re: [MBZ] GP Install - 91 300D 2.5T
I haven't checked them - because it;s easier to replace them than check them ;-) but the dash light still works fine. The dash light doesn't always catch them. For example, I have a weirdo 190D that had one open plug and one that draws almost exactly 2x the current. If 2x had not been in #1 hole the light would never have caught it. (The warning light works by balancing the current fed #1 against that drawn by the rest. It's an elegant little magnetic circuit. Translation: tricky beast, but very reliable [within its limitations], effective, and ultra cheap.) Testing them is easy using a digital ohmmeter. Just measure to ground from each terminal in the (disconnected) GP plug to the relay. This, it should be noted, did _not_ catch my 2x current eater. I used a clamp-on DC ammeter to do that when I couldn't figure out what was still wrong with the light after I replaced the one open plug and resoldered the GP relay (which it also needed). -- Jim
