PROCEDURES
Lash Adjuster Noise Check
If an abnormal noise (chattering or clicking noise), suspected to be a malfunctioning lash adjuster, is produced immediately after starting the engine and
does not go away, perform the following checks:
NOTE:
(1)
An abnormal noise caused by a malfunctioning valve lash adjuster is produced immediately after starting the engine and changes with the
engine speed, no matter what the engine load.
Therefore, if abnormal noise is not apparent just after starting the engine, if it does not change with engine speed, or if it changes with
engine load, the noise is not caused by a malfunctioning lash adjuster.
