CUSTOMER INTERVIEW
Interview the customer, if possible, to determine the conditions that exis t when the noise occurs. Use the Diag-
nostic Worksheet during the interview to document the facts and conditions when the noise occurs and any
customer's comments; refer to EI-10, "
Diagnostic Worksheet". This information is necessary to duplicate the
conditions that exist when the noise occurs.
• The customer may not be able to provide a detailed description or the location of the noise. Attempt to obtain
all the facts and conditions that exist w hen the noise occurs (or does not occur).
• If there is more than one noise in the vehicle, be sure to diagnose and repair the noise that the customer is
concerned about. This can be accomplished by te st driving the vehicle with the customer.
• After identifying the type of noise, isolate the noise in terms of its characteristics. The noise characteristics
are provided so the customer, service adviser and technician are all speaking the same language when
defining the noise.
- Squeak — (Like tennis shoes on a clean floor) Squeak characteristics include the light contact/fast movement/brought on by road conditions/hard surfaces
= higher pitch noise/softer surfaces = lower pitch noises/edge to surface = chirping
- Creak — (Like walking on an old wooden floor) Creak characteristics include firm contact/slow mo vement/twisting with a rotational movement/pitch depen-
dent on materials/often brought on by activity.
- Rattle — (Like shaking a baby rattle) Rattle characteristics include the fast repeated contac t/vibration or similar movement/loose parts/missing
clip or fastener/incorrect clearance.
- Knock — (Like a knock on a door) Knock characteristics include hollow sounding/someti mes repeating/often brought on by driver action.
- Tick — (Like a clock second hand) Tick characteristics include gentle contacting of light materials/loose components/can be caused by driver
action or road conditions.
- Thump — (Heavy, muffled knock noise)
Thump characteristics include softer k nock/dead sound often brought on by activity.
- Buzz — (Like a bumblebee) Buzz characteristics include hi gh frequency rattle/firm contact.
• Often the degree of acceptable noise level will vary depending upon the person. A noise that you may judge as acceptable may be very irritating to the customer.
• Weather conditions, especially humidity and temperat ure, may have a great effect on noise level.

1. Warm up engine thoroughly. Then, stop it.
2. Release fuel pressure. Refer to
EC-496, "
Inspection".
3. Remove ignition coil and spark plug from each cylinder. Refer to EM-46, "
Exploded View".
4. Connect an engine tachometer (not required in use of CONSULT-III).
5. Install a compression tester (B) with an adapter (commercial service tool) (A) onto spark plug hole.
• Use the adapter whose picking up end inserted to spark plughole is smaller than 20 mm (0.79 in) in diameter. Otherwise, it
may be caught by cylinder head during removal.
6. With accelerator pedal fully depressed, turn ignition switch to “START” for cranking. When the gauge pointer stabilizes, read the compression pressure and the engine rpm. Perform these steps to check each
cylinder.
CAUTION:
Always use fully a charged battery to obtain the specified engine speed.
• If the engine speed is out of the specified range, check battery liquid for proper gravity. Check engine speed again with normal battery gravity.
• If compression pressure is below minimum value, check valve clearances and parts associated with combustion chamber (Valve, valve seat, piston, pi ston ring, cylinder bore, cylinder head, cylinder head
gasket). After the checking, measure the compression pressure again.
• If some cylinder has low compression pressure, pour small amount of engine oil into the spark plug hole
of the cylinder to re-check it for compression.
- If the added engine oil improves the compression, piston rings may be worn out or damaged. Check pis-
ton rings and replace if necessary.
- If the compression pressure remains at low level despite the addition of engine oil, valves may be mal- functioning. Check valves for damage. Replace valve or valve seat accordingly.
• If two adjacent cylinders have respectively low compression pressure and their compression remains low even after the addition of engine oil, cylinder head gasket is leaking. In such a case, replace cylinder
head gasket.
7. After inspection is completed, install removed parts.
8. Start the engine, and confirm that the engine runs smoothly.
9. Perform trouble diagnosis. If DTC appears, erase it. Refer to EC-106, "
Description".

• Avoid fire and sparks.
• Keep parts away from heat source. Especially, be careful when welding is performed around
them.
• Do not expose parts to battery electrolyte or other acids.
• Do not bend or twist connection between quick co nnector and fuel feed hose during installation/

HOW TO SELECT MAIN BEARING
When New Cylinder Block and Crankshaft Are Used
1. “Main Bearing Selection Table” rows correspond to main bearing housing grade on left side of cylinder block.
• If there is a corrected stamp mark (B) on cylinder block, use itas a correct reference.
2. Apply main journal diameter grade stamped on crankshaft front side to column in the “Main Bearing Selection Table”.
3. Read the symbol at the cross point of selected ro w and column in the “Main Bearing Selection Table”.
4. Apply the symbol obtained to the “Main Bearing Grade Table” to select main bearing. NOTE:
Service part is available as a set of both upper and lower.
When Cylinder Block and Crankshaft Are Reused
1. Measure the dimensions of the cylinder block ma in bearing housing inner diameter and crankshaft main
journal diameter individually. Refer to EM-97, "
Inspection".
2. Apply the measured dimension to the “Main Bearing Selection Table”.
3. Read the symbol at the cross point of selected ro w and column in the “Main Bearing Selection Table”.
