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.

Note
l If the SST is not used, jump across the TEN termi-
nal and the GND terminal of the diagnosis con-
nector.
Ignition Timing
Inspection / Adjustment
1. Perform “Preparation.” (Refer to above.)
2. Check if the timing mark (yellow) on the crankshaft pulley
and the mark on the timing belt cover are aligned.
Ignition timing: 10 * f lo BTDC (at Idle speed)
3. If the marks are not aligned, loosen the distributor lock bolts
and turn the distributor to make the adjustment.
4. Tighten the distributor lock bolts to the specified torque.
Tightening torque:
19-25 N*m (1 .Q-2.6 m-kg, 14-19 ft-lb)
5. Disconnect the SST.

B2 COMPRESSION
COMPRESSION
If the engine exhibits low power, poor fuel economy, or poor idle, check the following:
1, Ignition system (Refer to Section G.)
2. Compression
3. Fuel system (Refer to Section F.)

INSPECTION
1. Check that the battery is fully charged. Recharge it if neces-
sary. (Refer to Section G.)
2. Warm up the engine to normal operating temperature.
3. Turn the engine OFF.
4. Remove all spark plugs.
5, Disconnect the ignition coil connector.
6. Connect a compression gauge to the No.1 spark plug hole.
7. Fully depress the accelerator pedal and crank the engine.
8. Record the maximum gauge reading.
9. Check each cylinder.
Compression:
1,256 kPa (12.6 kg/cm’, 182 psi)-300 rpm
Minimum:
883 kPa (9.0 kg/cm2, 128 psi)-300 rpm
Max. difference between cylinders:
196 kPa (2.0 kg/cm2, 28 psi)
10. If the compression in one or more cylinders is low, pour a
small amount of engine oil into the cylinder and recheck
the compression.
(1) If the compression increases, the piston, piston rings,
or cylinder wall may be worn.
(2) If the compression stays low, the valve may be stuck
or seating improperly.
(3) If the compression in adjacent cylinders stays low, the
cylinder head gasket may be defective or the cylinder
head distorted.
Il. Connect the ignition coil connector.
12. Install the spark plugs.
