Camshaft: Description and Operation
A steel camshaft is supported by five bearings pressed into the engine block. The camshaft sprocket, mounted to the front of the camshaft, is driven by
the crankshaft sprocket through a camshaft timing chain.
Motion from the camshaft is transmitted to the valves by hydraulic roller valve lifters, valve pushrods, and ball-pivot type rocker arms.
