If the motor was shut down immediately, it should be a good power washing, and change of fluids and filters. I put a 4x4 pickup in water lapping over the hood. Shut it down as soon as I realized what happened(unseen hole while fording), and then was pulled out. I towed it a short distance home, changed fluids and filters(there was water in the engine). Everything was fine afterwards. Drove that truck a lot for a couple more years before getting a new one.
[QUOTE='Bota Fan]Ditto. BTW, is the machine trashed? If not, what's the ticket for that kind of damage?[/QUOTE]
