All the rodbearings are in new like state.
If high revs kills an engine, either the bearings were at real high stress or the valves hit the pistons (valves start to float), or the engine gets so hot, the piston seizes. Neither thing looks like happened. If the piston seizes, it usually just stalls and doesnt break a rod because it goes fairly gradually with extended high revs (that said, it's cyl#6, the one that runs hottest..)
So hydrolocking still looks like a plausible cause, 2 cylinders next to eachother were locked, so the gulp of water went to the back (maybe inertia?)

Click me...
The landrovers, I can understand, showing off for the kids. But the rest...

Shows that BMW makes great cars and really bad submarines

BTW hydrolocking can of course also occur when a car gets off the road and slips into a ditch with standing water.
