OK, I'm gonna call BS on this. How could an engine run properly with a missing connecting rod, piston and rings? How much would those weigh? It would be massively out of balance. If it ran at all, I bet it would shake itself to death. Plus, the valves will still be opening. When the exhaust valve opened, wouldn't the scavenging effect of the other cylinders pull oil vapors out of the engine causing some smoking and oil fumes coming out the exhaust? And when the intake valve opened, wouldn't the vacuum in the intake system suck those same oil vapors up and into the intake system to burn? That would cause smoke? Not to mention the oil that would be slinging and squirting out of the hole in the crank journal. But I think the bottom line is that I don't think it could run well enough to move the car being out of balance that much. I am no engineer, but that is what I was thinking.
