3. If any abnormal noise is not eliminated by racing, check
the lash adjuster.
(1) Stop the engine.
(2) Set the engine so that cylinder No. 1 is positioned
at the top dead centre of the compression.
(3) Press the rocker arm at the area indicated by the
white arrow mark to check whether the rocker arm
is lowered or not.
(4) Slowly turn the crankshaft 360 degrees clockwise.
(5) In the same procedure as step (3), check the rocker
arm at the area indicated by the black arrow mark.
(6) If the rocker arm is easily lowered when the section
directly above the lash adjuster of the rocker arm
is pressed, the lash adjuster is defective, so replace
it.
Moreover, if it is felt to be so hard that the rocker
arm is not lowered when it is pressed, the lash adjuster
is normal. Check for other causes of the abnormality.
For Y-formed rocker arm at the exhaust valve side,
if one lash adjuster is defective and the other is normal,
it is impossible to press the rocker arm. In this case,
remove the lash adjuster and carry out the leak down
test.
NOTE
1.
A leak down test can be performed to accurately
determine whether the lash adjuster is defective or
not.
2. For the procedures for the leak down test and air
bleeding of the lash adjuster, refer to the Engine
Workshop Manual.
