Diesels are compression ignition engines. High compression makes high heat. The higher the compression, the higher the heat. Problem is when they are super cold compression isn't always that high and the heat that is made is having to overcome the frozen cylinders, head and fuel. So some engines use glow plugs to add heat. If they did come into contact with raw fuel inside an engine that wasn't turning it would be bad. Diesel is a flamable though so the mist in there contacting them when it is turning is ok.
Ether on the other hand is an explosive. If you have glow plugs on when that stuff is sprayed, it had better be turning. It will trash the glow plugs regardless but glow plugs and ether on a non rotating engine can turn your hood into a ram air style in a hurry. I had an old redneck boss at a chevy dealer once eat a chunk of cast iron and a valve from spraying that stuff in an old GM diesel. I really wish we had digital cameras back then. The video of him running around with that valve sticking in his eye socket would have been hilarious on youtube!!!

oRDERed a Genuine ford blockheater today at my dealership...Little more than the ebay deal but at least its local and I get warranty etc. Plus it gets yanked from paycheck so I will never know the money is missing LOL. Gonna attempt to ohm out the GPs like talked about here but witht eh miles on this thing I think im just gonna replace all eight while its apart. With 250K miles and original glowplugs its probably time.
Question. I googled injectors and they dont seem too cheap. How do you test them/know if they are bad. The truck runs great once its running. Its just that whole starting thing thats tough LOL

So the heat of the Glowplug itself does not ignite the fuel? I realize there is not an actual spark of course but always thought the glowplug assisted in igniting the fuel...But cylinder temperature does make sense. Do glowplugs turn off at a certain engine temp?
Thanks again everyone.
Thanks again everyone.
GP s are controlled by EOT ...

Update. Last night I got home and the highs for the day were 60 degrees ish around 40s when I got home...Truck started in 3 seconds. Drove it made sure it was pretty warm when I plugged her back in. This morning with over night lows in high 20s no luck again. One cylinder maybe two sounded like trying to fire and I am watching the voltage drop when I hear the GPR click on but no luck. So ambient temp drops and no luck on start. So block heater shows up today or tommorrow....Gonna do plugs after that. They are supposed to ship today. But still need to order gaskets and harnessess.
question. Is it safe to degrees the ***** out of these engines and wash all the oil etc that looms after a quarter million miles>? Id like to really clean up this sucker to start watching were leaks may be coming from etc and have a clean work space in general. Is alternator vulnerable? I know when I worked at a Volvo lot if we didnt bag the alternator when pressure washing we would fry it.
THanks

^^^^ x2 dont pressure wash it, u will kick urself if if get water in something like ur idm or a sensor like ur icp and ur truck starts running wierd, just for cleaning the engine. us some degreaser from a can, wipe it down or hose it off gently. and for some extra insurance i would cover all the important sensor and elctronics like the idm, icp, ipr etc with something like a zip-loc bag just so u dont get any water in them.

Good tip on no pressure wash. Simple green does wonders on grease so ill have to buy a gallon. Id love to find a good undercarriage wash in town but dont know where to start. THe folks that owned before me lived on a county road so mag chloride and dirt have a nice coating on the underside. If i could get this sucker clean it would make my life easier along with whatever mechanics I let touch in the future.
Ordered gaskets/harness kit today! Looks like Im gonna attempt this Glowplug swap on Sunday!
Is 14 foot lbs on Glow plugs and 97 inchpounds on valve covers correct?
And somewhere people talked about torquing injectors and rockers while in there?
