Austin Champ Engine Bay.

[engine bay, LHS, jpg] The Rolls Royce petrol engine is enclosed to make it waterproof for wading through deep water. The ignition leads are waterproof and the distributor is enclosed and vented to the air intake system. The tall snorkel guarantees clean air in water up to about two metres deep although the driver must either hold his or her breath or stand on the seat if it gets that deep.

The water-proofing measures make even simple maintenance difficult, and it is frequently necessary if much wading is done.
