YAY! You got it going without too much pain. I’m glad for you. Handy when you have the parts on hand.

Well, he didn’t have to swing an engine from the old oak tree out back. He had most of the parts except gaskets. I’d call that pretty painless.

Hey Fellas,
Thanks for all of the input & support
...but, this was the most STRESSFUL (2) weeks that I've had to deal with in a few years
"The ultimate measure of a man is not where he stands in moments of comfort and convenience
...but where he stands at times of challenge and controversy. MLK jr.
or, as I've always told my kids
Anyone can captain a boat in calm waters & on a nice day
...but, a real captain can "man the helm" in All situations...everyday
TBH
I certainly didn't know if these procedures would be successful
...& my first thoughts were to just take it to a shop (Isuzu Dealer)
...but,
1.) they would have probably charged me at least $1,000.00 to diagnose that the engine had sustained FATAL damage
...from the "runaway situation"
or
2.) they would have probably charged me at least $3,000.00 to change the Turbo...& exhaust manifold
...& then, when it didn't start up, claimed the engine had sustained FATAL damage
or
3.) they would have probably charged me at least $5,000.00 to swap out the Turbo, the ex. manifold & the (4) injectors
So, after "thinkin' it thru" I figured that I've been workin' on these trucks long enough
...that I could access "if" the engine was JUNK...myself...for free
...&/or swap the Turbo
...& (at the time) I didn't even think about the injectors potentially being damaged
Keep Calm
...& think it thru

Weekend Update
I put probably ~5 miles on the truck over the weekend
...test driving for drivability, to see "if" it still had the same "power" that it had & to see if the "miss" would go away
It still drives fine
...except for the "miss", it seems to have mostly the same amount of "power"
...& no warning lights are "lit" on the dash (which would indicate...a problem)
Also, no smoking (out of the exhaust)
...& no blow by (out of the oil system breather)
* Smoke from either of these (exhaust or breather) would potentially indicate a piston ring, cylinder scoring &/or valve issues
...& any of those things could have happened, when that Turbo impellor started disintegrating
...& "throwing" bits of metal into the air intake system
...that/then got "sucked thru the engine
Monday Update
I put ~40 miles on it yesterday, towing cars
The "miss" hasn't gone away
* It's not that noticeable when just idling
...or at highway speeds
...it seems most noticeable when accelerating from a stop
I did notice some fuel "puddling" around a couple of the injectors
...& may have to get some new seals (rubber O-rings)

Do it quick before the puddles become fires. 
Maybe you got a small chunk of impeller lodged in a valve or valve seat. Just drive it and make money with it with the intention you will have to replace the engine or truck eventually.

Research
One of the ladies at the Isuzu truck dealership parts counter (Yup, she's a "chick" but, seems ta do a pretty good job)
...looked up the injector O-rings, for a 4HE1 Isuzu 4 cyl. Diesel engine
Well, "come to find out" these injectors have (2) "gaskets" as they call 'em
They have the rubber O-ring (mid-way up the injector)
...&/also, a copper cone at (the bottom)
Hmmm...lemme see (brought some dissectin' tools)
This must be the copper "cone"
It came loose pretty easily (with just a bit of prying)
Here's the "nekked" injector tip (Jua'lla" don't look)
...& a top view of the "cone"
...& here's the other side, of the cone

Tuesday & Wednesday Update
I put ~80 miles on the truck yesterday
...& ~50 miles on 'er today
It still runs about the same (still has a slight miss)
...& still has a bit of Diesel fuel "puddling" around the first (2) injectors
So, I stopped by the Isuzu dealer
...& picked up (4) O-rings $1.77 ea. (x 4 = $7.08)
...& (4) Copper Cone gaskets $11.02 (x 4 = $44.08)
...& just to see, asked about the Injectors ~$315.00 ea. (x 4 = $1,260.00) no thanks...just checking
Plus, I stopped by Harbor Freight
...& picked up an injector "socket" cleaning brush ~$20.00
Also stopped by Walmart
...& picked up a small jar of Vaseline (light petroleum oil/grease) $1.00

Usually something catastrophic has to happen for a diesel to runaway like that. Have to agree with your assessment of an oil seal failed somewhere and fed it extra fuel. The only way to stop a runaway diesel, is by cutting the air supply. Need something big to place over the turbo air inlet so it chokes out. Definitely not shop rags, some have used fire extinguishers to choke them out.
I'm really surprised it didn't send a connecting rod out the side of the block and into orbit. Glad it didn't destroy the block.

2 month update
I've put a little over 3,500 miles on 'er since the "incident"
...& she is still runnin' pretty goodly
Besides my usual local/in town/citywide "runs" last week
...I had to go on a ~50 mi. tow (~100 mi. round trip)
...&/also, a ~100 mi. tow (~200 mi. round trip)
So, it's time for an oil change & grease job
Oil Change Drain Plug tip:
Wear/use a "shopping bag" as a disposable glove
After "breaking" the drain plug "loose"
...use your "gloved" hand to remove the drain plug
The bag helps protect your hand, from getting covered in dirty motor oil
...& simply "throw 'er away" when you're done
The top of the engine seems ta still be pretty dry
Don't see any specs, flacks or metallic dust...anywhere
All Ready to Roll

I'd get something to choke the engine out, incase you experience another runaway event.
