Check the engine oil and replenish or replace the oil if
necessary:

NOTE

If there is a only small amount of oil, air will be drawn
in through the oil screen and will get into the oil
passage.

If the amount of oil is greater than normal, then the oil
will being mixed by the crankshaft and a large amount
of air may get mixed into the oil.

If the oil is degenerated, air and oil will not separate
easily in oil, and the amount of air mixed into the oil
will increase_

If the air which has been mixed in with the oil due to
any of the above reasons gets into the high pressure
chamber of the lash adjuster; the air inside the high
pressure chamber will be compressed when the valve
is open and the lash adjuster will over-compress_
resulting in abnormal noise when the valve closes.
This is the same effect as if the valve clearance is
adjusted to be too large by mistake. If the air inside
the lash adjusters is then released,the operation of
the lash adjusters will return to normal.

2)Run the engine at idle for 13 minutes to Iet it warm up.
With no load on the engine, repeatthedrive pattern
shown in the illustration at left and check if the abnormal
noise disappears_The noise should normally disappear
after 1030 repetitions, but if there is no change in the
or more
noise level after 30 repetitionsthe problem is
probably not due t0 air inside the lash adjusters:)

(4)After the noise has disappeared, repeat the drive pattern
shown in the illustration at left a further 5 times

(5) Run the engine at idle for3 minutes and check that
the noise has disappeared:
