VALVE LASH VERIFICATION & ADJUSTMENT
NOTE: To obtain accurate readings, valve lash measurements AND adjustments should only be performed when the engine coolant
temperature is less than 60° C (140° F).
NOTE: The 24 valve overhead system is a "low-maintenance" design. Routine adjustments are no longer necessary, however, measurement should still
take place when trouble-shooting performance problems, or upon completion of a repair that includes removal and installation of the valve train
components.
