Many years ago, a mate's g/f was returning to Brisbane from her home town in his Toyota corronary, sorry corona. Near the NSW QLD border the Corona loses power and struggles to get to 20 mph downhill with a tail wind. So we hook up a tandem trailer head down to the border to pick up the car. We start the car and every thing sounds fine, no knocks or scrapes or any thing. My mate goes to drive it up the ramps and as soon as the front wheels hit the ramps, it refuses to go any further. In our haste, we had hired a tandem without a winch, which is odd as it had ramps. So anyway, my mate backs up and floors the corona aiming it at the trailer. As the corona hits the ramps, up it launches, he hits the brakes at the precise moment and there it is, sitting in the right spot on the trailer, didn't need to be moved forward or backward to get it in the right spot for tying down, which is lucky for him as the tow vehicle was his g/f's hotted up Holden Torana. Aussies will know what a Torana is, if you don't, just check out google images. So, we tie it down and drag it back to their house and unload the car. The next weekend, my mate says he's not pulling an engine that runs so proceeds to start the car and rev it past redline until it siezes with a very loud squeal. After it cools down, goes to start it and of it runs again, determined to kill the engine, revs it pasr redline again until it stops again with a squeal. Once again, after it cools down, it starts up again. And again, the revs are above redline and stops with a squeal, although this time its only about thirty secs after starting. This time, it doesn't start after cooling down, and my mate just says "now it gets rebuilt".
We had some funny problems removing the engine. After removing the bolt on stuff, manifolds and the like, we didn't have a floor crane at the time, so we decided a small japanese alloy four cylinder doesn't weigh much and we could handle it without the crane. So after removing the bolt-ons and the bonnet, we placed a water pipe accross the engine, and passed a rope under the sump in a criss cross patern. To do this, I just placed one arm down each side of the engine and passed the rope from one hand to the other, an easy job. We unbolted the engine mount as well as the gearbox and torque converter. As we lifted up the engine, the front of the car starts to rise with the engine as the weight is lifted. But then we couldn't lift the engine any further, it felt as we were trying to lift the whole front of the car up. We lower the weight back down and start to look over the engine for any thing that we had forgotten to unbolt. I just looked at my mate and said "found it" and untied the rope, removed it and then retied the engine by passing the rope under the sump without going under the cross member at the same time. On the second lift, because we thought the engine was heavier than what it was after the first try, we put a lot of effort into the upward heave. The engine flies up, because there's now no weight on the ropes, they move back, the engine piroets ninety degrees nose down, comes out of the sling and lands back in the engine bay nose down. We retie the engine to the pipe and gently lift it out of the engine bay. After we stripped down the engine, one big end bearing shell had turned behind its other half so two shells were on one half of the rod and nothing was on the other side. The engine was rebuilt and then put back into the car, and driven for thousands of miles afterwards.
The best engine I've come accross for running without oil, is the Chrysler hemi six. It was an engine in Australian Chryslers and was virtually indestructable. The local wrecking yard decided to test a few engines from different manufacteres by pulling a few from wrecks, draining the oil and water, then starting them and holding the throttle wide open. They timed each one to see which lasted the longest. Most lasted around ten minutes, but the hemi 6 kept going until the fuel ran out. I had a few Chryslers powered by hemi 6's and in my opinion, they were one of the most reliable engines ever made, as well as very torquey.
