(3) If any abnormal noise is not eliminated by racing, check the lash adjuster by the following procedure.
(1) Stop the engine.
(2) Set the engine No. 1 cylinder to the compression top dead center position.
(3) Press the rocker arm at the place indicated by the <- arrow in the illustration to check whether the rocker arm is lowered or not.
(4) Slowly turn the crankshaft 360° clockwise.
(5) By the same procedure as in step 3), check the rocker arm at the area indicated by the <- arrow in the illustration.
(6) Push down the rocker arm at a portion located right above the lash adjuster. If the rocker arm goes down readily, there is a malfunction of the
lash adjuster. Replace it with a new one in accordance with step (4).
In addition, when replacing the lash adjuster, make sure that all air is removed from the lash adjuster before installation. Then carry out
inspection in accordance with steps 1) through 5) to make sure that there is no abnormality.
NOTE:
(1) A leak-down test can be carried out to accurately determine whether the lash adjuster is defective or not.
(2) For the procedures for the leak-down test and for bleeding air from the lash adjuster, refer to Leak Down Test..
In addition, if the rocker arm feels very stiff or cannot be pushed down, the lash adjuster is normal. Therefore, check for some other cause of
the noise.
