The Series I Land Rover
1.6 litre Engine

This was
the engine which was installed in the first Series 1 Land
Rovers from 1948 to 1951 and over 61,000 were sold. It was
not however a new design for the new Land Rover because it
had been fitted to the Rover 60 car previously (otherwise
known as the P3). Interestingly, this engine produces better
fuel consumption than later engines used in the Series 2 and
3 Land Rovers.
To match the engine more towards its new role in a Land Rover
workhorse and to facilitate
its ability to work even on low quality fuel,
the compression ratio was lowered a little and a new camshaft
designed. These modifications gave more torque at lower revs
- though there was a loss of power at high revs.
The engine was of the 'inlet
over exhaust' type; which means that the exhaust valves were
on the side of the engine block but the inlet valves were
on the top.
The very earliest of the Series 1 Land Rovers had engines
with two black plates bolted to the right hand side of the
block. These were known as "side
plate" types. Later 1.6 litre engines had circular core
plugs in the side of the engine and are correspondingly known
as "core plug" engines.
Generally, the engine sump for the early Series 1's were stepped
but, by 1951, a 2 litre engine had been developed and the
gently curving sump for this new engine was also fitted to
the later 1.6 litre engines.
