0: 31-46 N-m (3.2-4.7 m-kg, 23-34 ft-lb) Possible Cause
Oil leakage in oil passage
Oil leakage in HLA
Insufficient oil pressure
Faulty HLA
Incorrect oil amount
Deteriorated oil Action Run engine 2000-3000 rpm.
If noise stops after 2 second-10
minutes(*), HLA is normal.
If not, replace HLA.
* Time required for engine oil to circu-
late within engine, includes tolerance
for engine oil condition and ambient
temperature.
Check oil pressure.
If lower than specification, check for
cause. Oil pressure; 294-392 kPa
(3.0-4.0 kg/cm’, 43-57 psi)-3000 rpm
(Refer to page 82-60)
Press down HLA by hand.
If it does not move, HLA is normal.
If it moves, replace HLA.
Measure valve clearance.
If more than Omm (0 in), replace HLA.
Check oil level.
Drain or add oil as necessary.
Check oil quality.
If deteriorated, replace with specified
type and amount of oil.

pressure (98 N,
10 kg, 22 lb) midway between the cam-
shaft pulleys.
If the deflection is not correct, repeat from Step 10 above.
