(reminder this is an older thread from 2021, but...) at the time I used an inspection mirror to look and I found no metal bits that i could see... but advice was if you were concerned to pull the injectors, which I wasn't willing to do at the time. Also the glow plugs showed no signs of recent...

Figured I'd follow up on this. After needing to pull my heads, at least two of the pistons showed very minor damage from metal going through the engine.. (no ring or wall damage) So reminder, check your glow plugs and swap them BEFORE they start to fragment! And remember to avoid the Chinese...

Success! 7/8 plugs needed a puller. All of the plugs were missing chunks, but nothing shiny to indicate any broke in the engine. So rolling the dice and not pulling injectors at this time. new TMS and new EESS installed. Wait light works! Stayed on for 10 seconds, it turned off, hit the...

Ohh just cause.. I took out the meter and checked the resistance on the glow plugs I removed. One of the two it at .5 Ohm, the other is at 2 milliohm. I'm just shocked the one reads .5.

Anything special on the lines, I don't have any spare parts at this point, but I'm not against buying some bulk lines from O'Reilly or NAPA and replacing them. As for clamps, all of the ones I've looked at (up to this point) do have the correct clamps on them. :) Ya, I bought the new box...

Ya, my EESS is shot. I have a brand new Natron? unit, along with new TSN to install. But I'm not going to do that until I've got the glow plugs swapped out. My plan is to pull an injector tomorrow, blow in compressed air and see if any bits of metal come out. Part of me is hoping that they...

Yup, I lubed them (WD-40), and VERY slowly pulled them out. (Had to use a split nut w/ shim, and then rotated the glow plug to pull it out.)

We’ll make that 2. At this point I’m going to just expect them all to break, so I’m giving up for today. I guess this my project for tomorrow.

Got one out.. of course the tip is completely missing! Glow plug has a 10mm hex. Says 746 on the head, and in the body 19207-12338771. MFG 3HCM3 guess I get to learn injectors now:mad:

Ahh 10mm is what I found on my HMMWV. Which is why I started ranting. ;)

I'm not sure I'm "skilled" enough with a vise grips to do that for all 8 cylinders.. especially the ones on the right side under the CDR and all the hoses.. as well as the one behind the generator on the left side.. YIKES! This is the crap I'm worried about, as I know the previous owner(s)...

Bullet ends, 10mm hex heads on them... (10mm is slightly larger then the 3/8" of what I believe are the normal glow plugs, thus the pulling tool doesn't fit.)

Just needed to vent.. Figured it might be useful to other people having this issue... The smart start box of course stopped powering the glow plugs. It's getting cold, so why would it work. Ordered a new box and 8 new glow plugs. Read on forums here and elsewhere I should get a removal tool...
