Ford- Fairmount/Zephyr 1978-1983 Repair Guide

Valve Lash


All Fairmont/Zephyr engines are equipped with hydraulic valve lifters or lash adjusters. Valve systems with hydraulic lifters operate with zero clearance in the valvetrain. There is no need of scheduled valve adjustment because of the hydraulic valve lifters ability to compensate for slack. All components of the valvetrain should be checked for wear if there is excessive play. If the valvetrain has been disassembled for any reason a preliminary valve adjustment may be necessary. Refer to the engine information ( ) for instruction on preliminary valve adjustment.
