Anyway, early Saturday morning I saw the engine running and I passed the booth several times during the day, each time the engine was running. I saw the same engine running all day Sunday, just idling away with no oil pan on it. Now maybe they had put roller bearings in it, I don't know. But they were confident enough to have this engine on display, running for many hours at a time and they were pretty confident that it wouldn't seize up. I still wonder to this day how they did it.
No, I didn't buy any of their product.
They probably made it idle so slow that it wouldn't hurt itself. If it's idling with no hood over it, no accessories and not being used (and there's water pumping through it!), it probably could run for weeks without burning up.
