I changed the glows on my 83 240/300d today because it was getting hard to start.

All five were shot!

Is this a record?

That's pretty impressive ... I had four out of six shot on the 603 and it wouldn't start in 50-degree weather. And that was not long after I had a compression text come up A-OK. Of course I had all 6 plugs replaced at that point.

Five good glow plugs in a 240D is probably a record!!!

I think he put an om617 in the 240D

Shot as in weak........or shot as in virtually nothing.

I'm doubting the latter.........or, you'd have been through a battery or two by now.

Shot as in when I tested them they did not produce any heat at all. I did not hurt my battery but the car would not start even after I ran the block heater. My expereince is they either glow or they do not. These did not.

I suppose it was when the last one failed that it stopped starting!

When I call it a 240/300d thats because it now has the five cylinder na engine in it. Its an 83 euro 300 NA engine.

I had a hard time starting one evening at work, I figured I had a bad plug or two. The next day I tried starting it in the morning (after being plugged in all night) and it wouldn't start, all 5 were bad.

I had all 5 bad 2 winters ago.

everything was just fine, went on an overnight road trip(100 miles each way) and got up in the morning to 5*F temps, no go- tested and replaced all 5. of course that would happen away from my garage, but at least I had 90% of the tools I needed along with. I think I had to buy a cheepo 8 mm wrench.

since then I have replaced all of them.(bosch duraterm- france)

I had 4,then a bad regulator causing my alt. to put out 16 volts,burnt all 5 bosch duratherms.New Gp. relay,then 5 new Beck an Arnley good.Except for #1 cylinder that needs a new one once a month now.
I need to do valve seals,and put Monark tipped injectors.

I've got 3 shot. I really need to change them, it's a real b!tch to start when the temps get below 20*. OTOH the TD has settled quite nicely into the recently vacated garage and I'm not sure how much it will venture out until springtime. I really don't want the rust to get any worse before I get around to fixing it.

I mix 1 part gasoline to 3 parts burnt motor oil.And spray the hell out of my vehicles,just in case I have to run in the salt.Its nasty the first rain,but it takes care of tailgaters.

How much overlap is there between glow plug operation and the alternator coming on line? Absent an afterglow timer, there should be almost none.
