Engine flooded with water, can it be fixed?

We had the same scenario this summer. A guy was idling through pretty heavy water. Sucked it in and stalled it.
We pulled the spark plugs, cranked it for a bit and it stated right up! Steamed a lot through (water came in through the exhaust).

This happens all the time around here when it rains and certain roads flood a bit. People think there cars are U boats and try to go threw a lot of water with them.
Pull the plugs and see if it will turn over, but chances are that a few rods are bent and the engine is toast.

1. high rpm spinning is #1 concern. if it was below 2500 there's a good chance he's ok.
2. you MUST get ALL the water OUT. pull plugs, turn crank, stick a hose on a vacuum and get it out.
3. change the oil. it now has water in the bottom of the sump.
4. minor surface rust will start to form in the cylinders. a little is ok. small scrapes can get by and the engine will still run. if it gets major, it's mostly a matter of if you can break it free to start it. As long as the rust isn't deep, you can get it running.
5. transmission breather is on a long hose at top of engine compartment.
6. don't recall diff breather location, may be piped into the cabin for the rear.
7. that's an awfully nice vehicle to attempt a stunt like that in. People who want to 4x4 really should know their vehicle first.
8. daimler did not put grease in the connections in this vehicle. they rely on o-rings. did it sit submerged for a while? if no, connections probably ok. If yes, they all need to be opened, wd-40'd, greased, and reclicked. the BIG harness on driver side to cabin will be a pita. i believe the ECU is pass. firewall, and it's mid-height. it's not bad. the bcu is under the fuse/relaybox. it's prone to corrosion, a pita to work on, and likely needs to be done.

Forget rpm's as a criteria, I've seen rods bent by simply cranking with a cylinder full of FUEL, not water!
Caution is urged, as sometimes the engine stops due to other reasons. As long as it didn't try to compress water it will be ok if you get right on it.
