2.Start the engine and perform gentle racing* several times
(less than times.)
If the abnormal noise stops by racing, the air is b led
from the high pressure chamber of the lash adjusters
and the function of the lash adjusters is normalized.
After raising the engine speed from idling to 3000
gradually (in 30 seconds), drop the
ally (in 30 seconds) to idling.
NOTE
lIf the vehicle is parked on a slope for the oil
in the lash adjusters will be decreased ‘andairmay
enter the high pressure chamber when the
is started.
lAfter the vehicle is parked for long, air may enter
the high pressure chamber because the, oil in the
oil passage will be gone and, it will take a time b efore
the oil is supplied to the lash adjusters.
3.If an abnormal noise does not stop by racing, check the
lash adjusters according to the following procedure s.
Stop the engine.
(2)Set the NG. cylinder of the engine to the compression
top dead center.
(3) Push the rocker arm indicated by the white arro w
mark as shown in the illustration at left and check
whether or not the arm lock goes down.
(4) Turn slowly the crankshaft
(5) Check the rocker arm indicated by the black arr ow mark
as shown in the illustration at left above (3).
(6) If the rocker arm can be lowered easily when th e
part of the rocker arm which is directly above the
top of the lash adjuster is pressed, the lash adjus ter
is defective and should be replaced with a new part .
In the same procedure as step 4, replace the lash
adjuster.
Furthermore, when replacing the lash adjuster, bleed
all of the air from the lash adjuster and then install.
After this, check that there is no problem by check ing
in steps to (5).
NOTE
lA leak-down test can be carried out to accurately
determine whether the lash adjuster is defective
or not.
l For the procedures for the leak-down test and
air bleeding of the lash adjuster, refer to
Furthermore, if the arm’ feels ‘extremely stiff
and cannot be lowered when it is pressed, the lash
adjuster is normal, so investigate for some other c ause
of the abnormality.
