A thrown piston connecting rod is something that spells death for many engines, but what does it actually look like when that happens? And what causes it to occur?
Thanks to this fascinating video, in which a small petrol engine from a lawnmower has part of its crank case removed, we get an inside view as it seizes following a rod failure. We also get to see the cause before the smoky engine death: there’s a hell of a lot of play where the con rod is attached to the crankshaft.
Sit back, relax, and get ready to learn!
