oh, and pop a true runaway 7.3 engine reving at over redline into gear and you will not stop the engine, You will most likely propel yourself, your truck, and anything in front of it through the nearest wall or building just before the transmission decides to tear itself into a bunch of pieces as well. Very stupid.

Here's another way to look at it. It takes all the power my engine has to get my 22K GCW up an 8% grade, but I can easily pull the load down from speed to a complete stop (at least once) going down the other side. Brakes can easily overcome the HP of the engine!

I have been around diesels for awhile and I have only witnessed one runaway.It was a ol Detroit 318 it got lugged down way low with rookie driving trying to back in to a tight spot and it just coughed and then started smoking out of the intake it was running backwards like stated earlier another driver jumped up and set the brakes and popped the clutch she shutdown. Thats the only one in twenty years or so , I'm not going to lose any sleep over it.

The question was not "will this ever happen", just simply if it were to happen, how to get the thing to shut off...and it was just for fun, just to see if you guys would come up with the same solution we did.
Thanks for the replies I learned some stuff from this thread. I had no idea there was such thing as a runaway that ran on it's own oil.

YA! The old Detroit 318 truck engine, a V 8 with a Pnut blower on top of it, would run backward on its own oil. Guy bumped a dock backing up, truck rolled fwd about 1 ft. in reverse gear and engine started running. Just kept accelerating until it blew apart in a big cloud of smoke. Exhaust came out aircleaner on a big white cloud.

In diesel mechanics class, im not in it yet but soon, they simulate this effect. By WOT a 4cyl cat, and you have to shut it down, Johns coffee can solution is the best thing to do for this whole situation, without doing damage to other running gear just cough it out.
