The intake (1) and exhaust (2) camshafts are made of
lightweight hollow cast iron. The camshaft timing
sprockets (3) are press fit onto the front of the camshafts
and are serviceable only with the camshaft. Engine oil
flows through the hollow center of the cams, direct
lubricating the camshaft journals. Camshaft lobes,
tappets, and valves are indirect splash lubricated from
the camshaft journals.
