However, most modern engines use a non-adjustable valvetrain where a properly-functioning hydraulic lifter or lash adjuster keeps the valvetrain running with zero clearance.

How does a hydraulic lifter work on an engine?

The pushrods actuate the rocker arms, which open the valves. Hydraulic lifters allow the valve lift to increase with engine rpm by filling up with oil as the oil pressure rises. The oil inside pushes the rocker arms further away from the camshaft, which causes the valves to open further.
