OTish - Facebook picture of disintegrated bottom end
I do not think I have ever seen one so totally
Can someone explain what happened here ? (In slo-mo)
I like the guy who explains it's an electrical fault,
because he sees a connecting rod broke off the starter motor.
Quite accurate = That is the most catastrophic engine failure
I’ve ever seen
My best offhand guess, too much combustion pressure,
in the cylinder, pressing on the piston, down through
the connecting rod, caused a break, and at guess 7,000
RPM, everything else, all over, goes to shit real quickly.
Connecting rods break, flail around, shattering entire
bottom of block, bust out all supports holding the
crank shaft in place. So bottom of block shattered,
falls off, crank shaft (perhaps still having parts
of connecting rods attached) departs.
I enjoy the random mechanical perversity, one connecting
rod (implying one piston still in proper place) sits
looking like it was neatly unbolted, still ready to do
For many years, out of morbid masochistic voyeurism,
I kept around one shattered block. That one was
created by a rod bolt failure. I think in my
move about 10 years ago, I gave into common sense
and got rid of the bad memento. I've still got
a little collection of bad twisted connecting rods.
