c. Push the rocker arm in the locations indicated by the white arrow mark as shown in the illustration at left to check if the rocker arm moves
down or not.
d. Slowly turn the crankshaft 360° clockwise.
e. Check the rocker arm in the locations indicated by the black arrow mark as shown in the illustration, using the same procedure as in step c.
f.
If the rocker arm can be lowered easily when the part of the rocker arm which is directly above the top of the lash adjuster is pressed, the lash
adjuster is defective and should be replaced with a new part. Furthermore, when replacing the lash adjuster, bleed all of the air from the lash
adjuster and then install. Check that there is no abnormality by carrying out the inspection in steps a to c.
NOTE:
-
A leak-down test can be carried out to accurately determine whether the lash adjuster is defective or not.
-
If the rocker arm feels extremely stiff and cannot be lowered when it is pressed, the lash adjuster is normal, so investigate for another cause of
the abnormality.

speed (over 30 seconds).
