detroit
One time I heard about a guy that had a Detroit run-off on him and he shut it down spraying a fire extinguiser into the air intake. { It must have caught it's oil when it took off }
A sad thing to see, but shows a Detroit on a full throttle death. Go to YouTube, Type in Detroit Diesel Meltdown in the search bar.
Don't know if this engine had cooling water to it, It looked it caught it's oil though.
Trust me the old 71 and 53 engines would and will run away. I have been there and done that. The first time it happened to me, I worked at Cat and I rebuilt a 4-71 detroit on a generator, the weekend mechanic put the governor on and set the governor and the rack and said it was ready for the dyno testing. I put in in the dyno and hit the starter and away it went, it was turning past 3000 rpm when I looked at it (it was a 1900 rpm engine) , then it caught a second wind and started climbing. This all happened in less than a minute and Im trying to get the outside air intake off, so I can choke it off. I did get it cut off, but the second wind was it picking up oil out of the base and burning it. Dont ask me how but I was always told that this was the reason for the second wind and possible boom next. Me and my helper had to take a nerve pill after that one, come to find out the other mechanic had set the governor wrong and I think the flyweights were on the wrong side of the shaft stop. This was when I started putting vise grips on the rack, on a first time start up.
I did have one other time on a marine engine 6-71. I was in the milatary and the night shift put a new governor on and something must have been wrong with it, engine cranked up and started past 3000 and I was doing this and that and nothing helped, so I grabbed a fire ext and unloaded it in the blower screen. It did stop it, but we had to take the engine out and rebuild it. I wish I had something to put over the intake screen, but there was nothing
OK my finger is getting sore from telling war stories, if you didnt remember anything I said, remember Detroits 71& 53 series will run a way. These are different animals that we see now a days, so mostly it takes an old timer like me to tell these stories. I do like this engines, they will run forever, regardless of how you treat them. I have one in an old Drott 40 excavator, I use for a yard machine, you cant kill it
Good Luck and Happy New Year to everyone
