Stuck at Cape York

Turbo engines and diesels especially will break catastrophically with water added and it does not take much, about half a cup full for a BMW X5. (My Grenadier was anticipated to have 2 bent con-rods, but the turbos were consider scrap).

A low revving petrol engine with a lower compression ratio is more likely to survive, (and much easier to fix).
Is non turbo diesel better than non turbo petrol? Not sure but history would suggest that as both the Willys and Land Rover series 1 were petrol and survived the Second World War that petrol is king in the most challenging of circumstances. Good call.

I've repaired a couple of older land-rover engines with water ingress, one just flattened a big end bearing, the other bent a conrod as well. So both fixed in a few hours for a few pounds.

WW2 jeeps would be even easier being sidevalve (flathead)

Not that those engines were comparable to modern engines.

As a diesel engine has a much higher compression ratio, the damage to the con-rods or piston is more likely to be catastrophic/serious. Conversly, diesel engines are usually more robustly made.

Fishing drowned LR109 Series IIIs from deep water as a TA soldier in the early '80s, we did not have to do much more than take the plugs out, expel the water and change the oil, unless someone had driven in at full noise and fury!
