It is responsible for adjusting the clearance between the rocker arm and valve stem, which allows the valves to open and close as needed. The adjuster will need to be replaced if the threads are stripped, or if it is cracked, or worn down. Remove the spark plug wire to prevent accidental starting and remove the valve cover from the engine to access the rocker arm. Detach the rocker arm and unthread the faulty adjuster.
