NVH Troubleshooting Chart Ð Engine Noise
Use the chart below to help you ®nd the cause of the problem.
1. Locate the area where noise occurs.
2. Con®rm the type of noise.
3. Specify the operating condition of engine.
4. Check speci®ed noise source.
If necessary, repair or replace these parts.

Measurement of Compression Pressure
1. Warm up engine sufficiently.
2. Disconnect injection tube on nozzle side and loosen injection
tubes on pump side. Release clamps on injection tubes.
+Use two wrenches to prevent delivery holder on pump side
from loosening.
3. Remove spill-tube assembly.
+To prevent spill tube from breaking, remove it by gripping
nozzle holder.
4. Remove all injection nozzles using Tool or a suitable tool.
5. Turn ignition switch OFF and disconnect harness connector
(black colored) at injection pump.

COMPRESSION PRESSURE
EM-11

6. Fit compression gauge adapter to cylinder head.
7. Crank engine and read gauge indication.
Crank speed: 200 rpm
Compression pressure:
Standard
3,040 kPa (30.4 bar, 31 kg/cm
2, 441 psi)
Limit
2,452 kPa (24.5 bar, 25 kg/cm
2, 356 psi)
Differential limit between cylinders
490 kPa (4.9 bar, 5 kg/cm
2, 71 psi)
8. If the pressure appears low, pour about 3 m!(0.11 Imp ¯ oz)
of engine oil through nozzle holes and repeat test.
For indications of test, refer to the following table.
Gauge indication during tests Trouble diagnosis
SEM857
+Piston rings are worn or
damaged.
SEM858
+If two adjacent cylinders
are low, gasket is dam-
aged.
+Valve is sticking.
+Valve seat or valve con-
tact surface is incorrected.
9. Replace nozzle gaskets and install injection nozzles.
New nozzle gasket installation direction is as shown.
