Operation
The V8 engine is an eight cylinder, water cooled unit comprising of cast aluminium cylinder block and cylinder heads. 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 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 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.
