Last week we had a cold snap in AL, it got down to 18 degrees, so I needed to add anti-freeze to the 816 wrecker.
Since I had two hot batteries I figured there would be no prob starting even though it was already in the 20's with a frigid wind blowing out of the west.
I cranked her up and she was idling just fine although a lot of white smoke was coming out of the stack.
Since that was not unusual so I let her slowly continue to warm up. I slowing increased pressure on the accelerator pedal to idle it up some more.
I noticed that the white smoke had not decreased so I let up on the pedal.
The RPMs continued to increase and I hit the shut off but it kept running.
I jumped out of the cab and cut the fuel line to try to shut it off.
The engine was roaring now and I realized that she was sucking oil into the cylinders from somewhere and that I had a "run away" diesel on my hands.
The cloud of smoke was so thick I could not see my shop but I felt my way to the door and grabbed a hammer and a large cloth towel.
I ran back to the truck and knocked the mushroom off the air cleaner and stuffed the towel into it.
The engine choked down and died.....another few minutes and it prob would have locked up or detonated.
It left a huge mess in my yard and across the street at my neighbors.
I paid to have his vehicles washed (and washed all mine that were in the path of the smoke) and tomorrow I break out the pressure washer to clean buildings.
The best guess is that the O-rings in one or more of the injectors failed allowing oil to get into the cylinders and cause it to attempt suicide.

a 50/50 mix of antifreeze and water i believe will raise the boiling temp to 265* and a 70/30 will raise it to 275*
