quote Originally posted by maryjane: Difficult to say. Watching it closely, the engine comes completely out of the engine bay, still running at 4:35. It settles back down into the truck about 1 second later, unattached but still running and is wallerin (that's a real word where I live) around in the engine compartment so much the whole front end of the truck is shaking. The engine, after settling back into the truck, is still running a a much lower rpm at 4:40 as they are using the fire extinguishers. CLICK FOR FULL SIZE May be an air/oil explosion that threw the engine out and not a catastrophic engine disassembly, tho it is possible a disaster on the bottom end could have resulted in the oil/air explosion. CLICK FOR FULL SIZE Notice there are no flames yet, except just a bit of orange under the truck.

At one place I worked about 15 years ago, a kid over-revved a Cat in a cabover Freightliner on a downhill run, threw a couple of rods, knocked a hole in the block big enough to pass a grapefruit through and set the truck on fire, most likely because of the oil mist. The fire went out quickly on its own.

One of the dispatchers kept a rod cap on his desk as a paperweight. You could hardly tell what it was, it looked more like a rock.

Edited because I remembered that it was a Cat.
