i'm going to add a new question to this debate:
last summer i dropped an os max 40fp into a farmer's field.
we could not find it until he harvested in the fall.
the plane was totalled but the engine was buried in the dirt and after i washed it and reassembled it it ran beautifully.
only one problem:

the outside of the engine is stained black where water and the various elements in the top soil had come in contact with the crankcase and muffler.

will the crock pot and antifreeze work on this discoloration?
