LASH ADJUSTER INSPECTION

If an abnormal noise (knocking) that seems to be coming
from the lash adjuster is heard after starting the engine and
does not stop, carry out the following check

NOTE

The abnormal noise which is caused byproblem
with the lash adjusters is generated after the engine
is started,and will vary according to the engine
speed: However; this noise is not related to the actual
engine load.
Becauseof this, if the noise does notoccur
immediately after the engine is started, if it does not
change in accordance with the engine speed,or if it
changes in accordance with theengine load,the
source of the noise is not the lash adjusters

If there is a problem with the lash adjusters, the noise
will almost never disappear; even if the engine has
been run at idle to let it warm up.

The only case where the noise might disappear is if
the oil in the engine has not been looked after
properly and oil sludge has caused the lash adjusters
to stick:

Start the engine.

2)Check that the noise occurs immediately after the engine
isstarted; and that the noise changes in accordance with
changes in the engine speed.

If the noise does not occur immediately after the engine
is started, or if it does not change in accordance with the
engine speed, the problem is not being caused by the
lash adjusters, so check for some other cause of the
problem. Moreover, if the noise does not change in
accordance with he engine speedthe cause of the
problem is probably not with the engine(In these cases
the lash adjusters are normal )

3)While the engine is idling, check that the noise level does
not change when the engine load is varied (for example
by shiftingfromN4D):

If the noise level changes, the cause of the noise is
probably parts striking because of worn crankshaft
bearings or connecting rod bearings. (In such cases, the
lash adjusters are normal:)

(4) After the engine has warmed up, run it at idle and check if
any noise can be heard.

If the noise has become smaller or has disappeared the
cause of the noise was probably that oil sludge had
caused the lash adjusters to become stuck: If this
happens, carry out the following check: If the noise level
does notchange, go to step 5.

Let the engine cool down sufficiently:
Turn the crankshaft two full revolutions.
