      Personally, setting 40 years and finding some water in it, I'd put it on the engine stand, pull the pan and see what I had. It could be just fine or there could be rust on all the cylinder walls and journals.

      That first turn could be more destructive than any other event. If it had set a couple of years and no moisture I'd probably still pull the pan but I'd be more comfortable just changing the oil, turning the pump and rolling it over.

      That's just me but I hate to see carnage that I could have prevented by a couple hours extra work.

        Your going at it wrong trying to turn the crank by the crank bolt. pull the starter, use a crow bar and work on the flywheel teeth. also if you suspect stuck valves remove the rocker arm assy. work it back and forth (Flywheel) after lots of diesel is poured into the cylinders. be patient, let the diesel work.

          what doofus said, but still recommend pulling at this point, especially after finding water.
