Start up Smoke

They don't get "shorter". I don't mean to offend if I read that wrong.

I assume you meant "shorted". They do "wear" electrically which is the reason they don't last forever. Your truck has about 120K right? If they're the stock glow plugs (didn't read about a replacement in your original post) then I would definitely just do them because they have 120K on them.

I NEVER tell someone to throw money at something, but glow plugs are really important to the starting and first couple minutes of drivability so it's not a bad idea to do them at 120K miles. You might consider replacing the small harness under each valve cover while you're there.

On some of the old trctors the tips would actually get shorter, thus reducing the area of heat on plug. And yes I am kinda ignorant about diesel stuff, so thanks for being kind to me. I am probably going to stick plugs in. Like I said, injectors just dont make logical sense to me, but plugs do.

Well I changed the glow plugs out. The old ones all worked fine when I hooked them up to my battery charger. On the old ones only about one inch would light up compared to more on the new mtorcraft ones. Guess I will see in the morning. If you have any more ideas, please lay them out there. If the intake heater didn't work, would that cause the problem?

The truck never did this before, when started cold? This just started happening?

Another question? Does the smoking when first started only happens when it started cold? If the truck is plugged in does it still smoke? Also is it alot of smoke, or just a haze?

Not sure about the poug inthing, but it dumps smoke like coal train, except white. I'm gonna try leaving the plugs on longer in the morning and see what happens then.

If you can plug it in tonight, let us know if it still smokes....

I pulled glow plugs on my '94 a few years ago with 300k miles on it (i do not know if they were originals). I did the "test light" test and all eight made the light, light up bright.

I tested each glow plug with a 12 volt jump box and infrared thermometer 4 or 5 would get to about 200* and the others turned pink just at the tip, a new one will turn red for about on inch.

I think the best way to test is to take a 100 amp amp meter and hold it rite on to of the glow plug relay, connecting the relay studs to the studs on the amp meter and then you will see how many amps the glow plus pull. Use the meter on a new glow plug so you know how many amps 1 plug pulls
