Yes, and I've seen it happen MUCH more often on Detroit Diesels - the two-strokes-cycle diesels, NOT the 6.2s also designed by Detroit Diesel.
That's why, when you first start an engine - you make sure you've got some way to shut it down quickly. That's Mechanics 101. When we worked on Deere's with 2-53 Detroits, we always had somebody stand near the engine with a rag to plug the air-intake if needed if an engine ran wild. Same goes for V8 diesels. If unsure - have somebody ready to plug the air intake if there's trouble. Easy to do.
Again - if a person puts an engine together wrong, it can blow up. If a person puts a gas engine carb or governor together wrong, it can blow up. Etc., etc. Heck, you can put a spark plug in "wrong" and ruin an engine.
Screw up can have bad results on just about anything. I fail to see why this "special" injection pumps are put into a category all their own by some people.
By the way, I got 520,000 miles out of my J-code 6.2 in my 87 Suburban. I also have many here with over 200K that have never been apart and run fine. And yes, there are many that failed much earlier. Many people forget that the 6.2 diesel was designed by Detroit Diesel to be an equal power-replacement for 305 gas engines (5 liters), and nothing more - at the time it was created. Adding a turbo, and/or increasing the bore slightly to 6.5 liters put them well beyond their original design. And, driving a stock 6.2 hard and lugging it - also put it past it's design limits.
