My point is i’m replying to this post on a device made in China. You’re reading it on a device made in China. We don’t produce resistors or capacitors in the United States so most of the components in the start box are made in China. The vast majority of things we use every day are made in China...

My “universal” diesel compression gauge wasn’t so universal, but fortunately i was able to disassemble one of my old injectors and found an adapter in the kit that would thread into that so that worked out. Who knows how accurate this gauge is, so i checked multiple cylinders. Method was to...

Yeah.. if things happen to be good in regards to the compression i’ll for sure be looking in the line and IP direction. In my cursory inspection of the lines i had’t seen any obvious kinks.. it appears to have the same patina of the other lines so nothing about it would suggest it wasn’t...

I plan on buying a set of the hallowed “quality” glowplugs if for no other reason than to bench test them against some ching chong plugs to see if the hype is legit. Not sure where the U.S. Government sources their glowplugs but my truck roasted that one with less than 35k on the clock, and at...

Only I just pulled out a swollen glow plug THAT WAS NEVER EVEN PLUGGED INTO THE START BOX. It's not an argument. I don't care if a guy has been doing this 1000 years. Maybe in 497 cases out of 500 the start box IS to blame. Hey, HIS money, he can use it to replace stuff that doesn't need to be...

Thank you. This is the kind of straight forward, knowledgeable advice and info I was looking for. Shortly after I bought the truck I was driving it to Harbor Freight.. stopped at a red light.. people honking and waving.. I'm the coolest kid in town. Light turns green I hit the accelerator and...

Well.. I read THIS one.. it said to send it to some other department. If you could point me in the direction of the TM that covers my issue on the M998 that would be super helpful. There are a TON of TM’s and aren’t particularly well titled.

Thank you for your perspective. That’s exactly what i’ve been looking for. That extreme heat is what lead to the leaky injector theory. I have used an infrared thermometer while the engine was running to compare temps between the different cylinders and everything is pretty uniform. I’ve used...

I hate to break it to you Captain America, but it was a “Made in USA” glow plug it spit out FIRST. I then replaced ALL the glow plugs. 7 of them have been perfect, it’s this one cylinder that keeps eating them. Glow plugs are not some high science and these trucks are essentially 1950’s...

No blowby at the dipstick or oil filler and no bubbling or nastiness at the radiator or overflow tank suggests to me if my compression is low that it’s likely a valve not closing all the way. Might just be gummed up. It runs and drives alright and had enough compression to blow two of the glow...

Starting easy in -27 degrees suggests they are probably warming up. Watching the meter on the dash pulse shortly after starting to complete the warm up cycle indicates they are drawing current. I have had no reason to suspect they don’t work beyond this paranoia about import parts people seem...

They did. Several people did. That’s why I replaced the injectors to begin with. Then I replaced them again because people said the import injectors I used were junk. Still having the problem with Delphi injectors so its safe to rule out the injectors. I ordered a diesel compression gauge and...

Here’s the glow plug from the ajacent cylinder.. it was installed when I replaced all the glow plugs last year. I’ve also included a pic of a brand new glow plug for comparison. All the other glow plugs look the same as this. If the controller were overcycling to the extent it was incinerating...

I DID check the glow plug lead. I replaced the original injectors just because I had no idea how old they were and was going to replace them anyway. I replaced the second set because everybody and their cousin swears the import injectors are crap.. yet i’ll still have people chiming in about it...

I have put a meter on the lead. 24v is NOT present after the initial warmup cycle. It was one of the very first things I did. I stated that right from the get go. This is the FOURTH failure of the glowplug in this cylinder. No other glow plugs are so much as swollen.

That’s not how electricity works. A “bad wire” would provide low or no voltage to the glow plug. The same amperage and voltage is delivered to all the glow plugs, just like in your home wiring. All the outlets have the same amperage available. Your cell phone charger doesn’t bake because it is...

I can tell you that taking the oil cap off and putting my hand across there isn’t any blowby there. I ordered a diesel compression set off Amazon for $40 delivered that’ll be here Wednesday I’ll check it then and let you know what I find out. It won’t let me post a video of it running here -...

My 2 pops both happened when I was accelerating from a stop. This is my third injector.. so i’ve pretty much ruled out having a drippy injector. I’m going to grab a Harbor Freight diesel compression tester and check that cylinder. I have a feeling i’m going to find less than ideal compression on...

Here’s what the glow plugs in the offending cylinder end up looking like..

The theory was that fuel was accumulating on the glow plug and that during the normal glow plug heat cycle the fuel was igniting and that was what was roasting the glow plug. They end up looking like they were made of glass and snapped off. Very sooty as if they’d been in a fire. As to how it...
