ENGINE
Operation
The V8 engine is an eight cylinder, water cooled unit
comprising of cast aluminium cylinder block and
cylinder heads.
The centrally located camshaft is driven by the
crankshaft via an inverted tooth chain. The valves
are operated by rockers, pushrods and hydraulic
tappets. Distributor drive is by skew gear from the
front of the camshaft.
The two banks of steel cylinder liners which are
pressed down to stops in the cylinder block, are set
at 900 to each other. The crankshaft is carried in five
main bearings, end-float being controlled by the
thrust faces of the upper centre main bearing shell.
The aluminium alloy, pistons have two compression
rings and an oil control ring and are secured to the
connecting rods by semi-floating gudgeon pins. On
later 4.2L engines the gudgeon pin is offset 0.5mm,
identified by an arrow mark on the piston crown,
which must always point to the front of the engine.
Plain, big-end bearing shells are fitted to each
connecting rod.
