good reason to carry a CO2 or Halon Fire extinguisher in the cab a couple blast in the air intake will remove the oxygen and the engine will die. I would prefer halon, as less thermal shock. Some how that engine started sucking oil from the crankcase.

If your referring to the white smoke that's water not oil. Oil would be black smoke. Water comes out a s white smoke.

Diesels can also blow White smoke. White smoke can happen from an enrichment condition as well. Look at more diesel run-away videos and you will see plenty of diesels putting out white/grey smoke as well. Here's a compilation that shows it Youtube. Heck, even gasoline engines can have bluish/whitish smoke when burning oil as well.
