1. Check engine oil and add or change oil if required.
NOTE: If the engine oil level is low, air is sucked from the oil
screen, causing air to enter the oil passage.
NOTE: If the engine oil level is higher than specification, oil
may be stirred by the crankshaft, causing oil to be mixed
with a large quantity of air.
NOTE: If oil is deteriorated, air is not easily separated from
oil, increasing the quantity of air contained in oil.
NOTE: If air mixed with oil enters the high pressure chamber
inside the lash adjuster from the above causes, air in the
high pressure chamber is compressed excessively while the
valve is opened, resulting in an abnormal noise when the
valve closes. This is the same phenomenon as that
observed when the valve clearance has become excessive.
The lash adjuster can resume normal function when air
entered the lash adjuster is removed.
2. Idle the engine for one to three minutes to warm it up.
3. Repeat the operation pattern, shown in left figure, at no load
to check for abnormal noise. (Usually the abnormal noise is
eliminated after repetition of the operation 10 to 30 times. If,
however, no change is observed in the level of abnormal
noise after repeating the operation more than 30 times,
suspect that the abnormal noise is due to some other
factors.)
4. After elimination of abnormal noise, repeat the operation
shown in left figure five more times.
5. Run the engine at idle for one to three minutes to make sure
that the abnormal noise has been eliminated.
