Didn't realize it was turbo. Turned truck back on and ran normal for a few minutes. Rev-ed the motor a little and rpms ran away to 1900 white oil raining from the sky. Turned the truck off but kept right at 1900 with smoke so thick couldn't see my hands in front of me. Boss had a clever trick to Pop truck in highest gear you can shove it into with the sole intent to stall it. Used about 3-4 gallons of oil in the fiasco. It ran on these high RPM's for a few minutes before I could turn it off.

It is nice to have instant access to old timers who've "been there, done that." Stopping a run away turbo was not taught in class at driving school.

Motor still runs great 2.5 years later. Its a CM870. Turbo had about 700,000 miles on it cummins turbo. Made for an unforgettable moment.

But it worked real good to stop the turbo. Probably wont work all the time but I think its a once in a lifetime experience.

Some oil from dryer in the pic.

Thank you for sharing that with us. It explains your first post well, but it does sound like you got quite lucky in what was done.

I also like the fire extinguisher idea. Was curious about that.
