A powder metal rocker arm is provided. The rocker arm may be connected to a cylinder head of an engine to assist in transferring motion between engine components. The rocker arm includes a pivot aperture formed therein to facilitate pivoting of the rocker arm with respect to the cylinder head. The rocker arm is formed of a metal alloy powder. The metal alloy powder is compacted to form an intermediate member. Secondary features, such as apertures and other weight reducing features may be formed in the intermediate member. The intermediate member is then sintered to form the rocker arm.
