How Do Car Engine Lifters Work In a Car?
Your vehicle’s lifters actuate both the exhaust and the intake valves. The cam is equipped with egg-shaped lobes that allow the engine lifters to move upward and downward. As the heel of the cam is the wide and short end of the lobe, the cam moves. That movement creates little pushes that cause the engine lifters to go up and down. The engine lifters move the valves into a closed as well as open position. For a vehicle that has a non-overhead cam engine, the lifters move a push rod downward and upward. This in turn moves the rocker down and up as well. The front of the rocker then moves the valve.

What causes the camshaft lobe to shut?
During the camshaft lobe’s lift phase of travel, the lifter piston is compressed, which causes the oil inlet hole to shut . Oil is almost incompressible, so the pressure inside the lifter makes it almost completely solid. This allows the camshaft to transfer its energy to the pushrods while the valvetrain remains tight.
Why do lifters wear down?
