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.
