Water will not destroy an engine. All you have to do is rinse and dry...............
Are you familiar with the Top Gear episodes I am speaking about?
The final episode they put the truck on the top of a building and blew up the building.
The drove the truck onto the stage at the end of the show. The frame was completely broken through on the one side. It still ran though.
But everything else will fail in a short time. Remember that bearing seals are designed to keep oil IN not water OUT.
I bought a flood truck and found this out the hard way. Eventual total engine failure.
