Step 4
Turn the ignition switch to the "ST" position, so that each cylinder runs 4 to 5 compression strokes.
Next
Step 5
Individual cylinder pressure readings should not be less than 75% of the maximum and any cylinder pressure
gage reading should not be less than 750 kPa.
Next
Step 6
Check the pressure gage readings for each cylinder, after the completion of four compression stroke.
Readings is explained as follows:
(a)
Normal Conditions: The cylinder pressure rapidly increases
and reaches the required uniform pressure value.
(b)
Piston Ring Fault: The first stroke pressure is low, increasing
in the following strokes, but the pressure has not reached
normal levels. Add engine oil in the cylinder, the pressure
increased significantly.
(c)
Valve Fault: The first stroke pressure is low, and can not be
increased in the following strokes. Add engine oil in the
cylinder, the pressure is not increased.

Step 7
End of the test.
2.6.7.4 Engine Noise Diagnosis
Engine vibration is actually referring to the engine resonance noise. When the engine's vibration frequency is the same as the
vibration frequency of a fault, the noise will be perceived. Severe vibrating usually generates big noise, and it is generated by internal
parts fracture or serious engine wear and tear. A slight vibration can be heard, but the sound is not big. Slight vibration is due to the
engine internal parts wear, loose or engine external components broken and it can lead to serious or slight vibration. In the engine
noise diagnostic, the resonance noise cause must be found in order to eliminate the fault.
2.6.7.5 Noisy when there is engine load
Step 1
Check whether drive belt tensioner is too tight or wear?
Yes
Replace/ adjust the drive belt tensioner to the
specified value. Confirm whether the fault is
fixed.
No
Step 2
Check the exhaust system. Whether the system is interfered with the other body components or scraping to
ground?
Yes
Relocate and install the exhaust system to
confirm whether the fault is fixed.
