I'm picturing a long, slow, deafening screech that sounds like it came straight from the depths of Hell. This accompanied by everything within a 1.5 mile radius shuddering, things falling from walls and off of shelves, babies crying, and people everywhere praying for their salvation, as the End of Days is surely upon them. For added hilarity, someone should put that thing out on the curb along with an ad on CL: "Large piece of steel, free for the taking. On the curb. Bring a friend and a truck, this thing is heavy!" Then sit back, and watch the scrap vultures come by, thinking it's like a car door or something. Then watch the ensuing creaming of overalls and fistfights between rival scrappers as to who gets it. Then, once the dust has settled, watch the victor try to figure out how to get it out of there.

Imagine if it was something as simple as just getting the timing of motor wrong when assembling? "Alright, who's the rear end in a top hat who installed the 400foot long timing belt wrong?"

That is insane. I love how the internal combustion engine can just be scaled up or down depending on what you need it to power, it's so loving cool.

I wish I had a picture of this one, maybe you don't think it's as cool as I thought it was. I was on board one of the ships I work on which has a large diesel, similar to the bend rod up above. The ship is three years old and has pretty much been in constant operation ever since being launched. When the main engine is not running, the jacket water is kept at near operating temp, being heated by heat exchanger from the ship's boilers. They had to shut down the boilers for several days in port, and simultaneously the jacket water remained under pressurized circulation (as mentioned, it is its own closed system). When the jacket water reached ambient temperature, the jacket seals on several of the cylinders failed, and jacket water began dumping out externally all over the top of the block, spilling hundreds of gallons down the main engine all the way to the bottom of the engine room, several decks below. Typically these engines just never leave operating temperature even when they're shut down, so the first time they did, seal failure. It was pretty cool to see, but I didn't have my camera. They managed to get replacement seals and install them in time to depart.

When I sold my MSP, at 37,000 miles the LSD was going. I was told by the tech I know at the dealer (I traded it in for a 07 Mazdaspeed3 GT) that it was over $8k in repairs to get my car all back together.

Probably a case of "dammit, left my wrench in there. going to be laughed or yelled at. just gonna pop in and see if....oh poo poo". I remember my uncle telling me a similar story. Guy "just had to" pop into the boiler, or some contraption for storing pressurized steam anyway, without letting anyone know. It got pressurized and they only ever found his watch.

All two strokes scavenge exhaust. The fresh fuel/air charge pushes the exhaust and itself into the muffler, then get bounced mostly back into the combustion chamber. This is why stratified scavenging has been exploding in the OPE field the past few years.

From the link posted earlier it looked like the piston jammed in the sleeve somehow, causing a portal to Hell to open and allowing the demon hands of Beelzebub to reach through and do that to the lower connecting rod. I find those factory photographs really entrancing but it took me a bit to realize why. Yes there are giant engine parts everywhere giving a strange mixed sense of scale, but I was really just struck at the lack of visible safety equipment. I'm so used to seeing shielding and brightly colored easily accessible kill switches on machinery and people wearing ear and eye protection that the images just hit me as very odd.
