Ok, so I removed the engine. I stripped it down to the block and crank and removed it by myself. MAN that thing is heavy!

Surprisingly I found no engine damage!

The crank was hard to turn because the oil pump that is mounted on the crank destroyed itself! It's full of aluminum shavings from the pump gears gouging out the pump walls.

Since then I've re-installed the crank and tightened up all of the crank caps ( not torqued, but tight ). The crank now turns completely smooth and easy like it should, as long as the oil pump is not installed.

So now the question is... what in the world would cause an oil pump to cannibalize itself?!
Was it something that I did, or am I just very unlucky?
