I rolled a large crane truck on I-4. Was either put it in the median or run over a small Datsun pulling a boat that went sideways in front of me in the rain. Truck was a chevy 6000 series diesel and rolled 3/4 of the way ending up on the drivers side. Engine was dead as soon as it went over, instant lockup. Had to pull the injectors to get it to turn over. All cylinders were full of oil, but after changing all the fluids it started up and is still of the road today. Has a brand new crane, hood, doors, mirrors, fenders, but the engine is ok. I think as soon as a crankcase full of oil gets topside there is no way a motor will keep going. There was no water in the intake, and I don't see how there could be unless something else was broken.
