push rod

push rod
The rod that connects the valve lifter to one end of the rocker arm. Used on valve-in-head installations where the cam is below the piston and the valves are above the piston. The rods are moved by the cam and activate the valve lifter. Engines with overhead cams do not need push rods because the camshaft connects to the valves directly.
