A: INSPECTION
NOTE*:
When disconnecting fuel injector connector, the malfunction indicator light illuminates and DTC is stored in ECM memory.
Therefore, carry out the clear memory mode
Regular clicking soundSound increases as engine
speed increases. Valve mechanism is defective.
Incorrect valve clearance
Worn valve rocker
Worn camshaft
Broken valve spring
Heavy and dull clankOil pressure is low. Worn crankshaft main bearing
Worn connecting rod bearing (big end)
Oil pressure is normal. Loose flywheel mounting bolts
Damaged engine mounting
High-pitched clank (Spark
knock)Sound is noticeable when
accelerating with an overload. Ignition timing advanced
Accumulation of carbon inside combustion chamber
Wrong spark plug
Improper gasoline
Clank when engine speed is
medium (1,000 to 2,000 rpm).Sound is reduced when fuel
injector connector of noisy cyl-
inder is disconnected.
(NOTE*) Worn crankshaft main bearing
Worn bearing at crankshaft end of connecting rod
Knocking sound when engine
is operating under idling speed
and engine is warmSound is reduced when fuel
injector connector of noisy cyl-
inder is disconnected.
(NOTE*) Worn cylinder liner and piston ring
Broken or stuck piston ring
Worn piston pin and hole at piston end of connecting rod
Sound is not reduced if each
fuel injector connector is dis-
connected in turn. (NOTE*) Unusually worn valve lifter
Worn cam gear
Worn camshaft journal bore in crankcase
Squeaky sound — Insufficient generator lubrication
Rubbing sound — Defective generator brush and rotor contact
Gear scream when starting
engine— Defective ignition starter switch
Worn gear and starter pinion
Sound like polishing glass with
a dry cloth— Loose drive belt
Defective water pump shaft
Hissing sound — Loss of compression
Air leakage in air intake system, hoses, connections or mani-
folds
Timing belt noise — Loose timing belt
Belt contacting case/adjacent part
Valve tappet noise — Incorrect valve clearance

General Description
C: CAUTION
Wear working clothing, including a cap, protec-
tive goggles, and protective shoes during opera-
tion.
Remove contamination including dirt and corro-
sion before removal, installation or disassembly.
Keep the disassembled parts in order and pro-
tect them from dust or dirt.
Before removal, installation or disassembly, be
sure to clarify the failure. Avoid unnecessary re-
moval, installation, disassembly, and replacement.
Be careful not to burn yourself, because each
part in the vehicle is hot after running.
Be sure to tighten fasteners including bolts and
nuts to the specified torque.
Place shop jacks or rigid racks at the specified
points.
Before disconnecting electrical connectors of
sensors or units, be sure to disconnect the ground
cable from battery.
All parts should be thoroughly cleaned, paying
special attention to the engine oil passages, pis-
tons and bearings.
Rotating parts and sliding parts such as piston,
bearing and gear should be coated with oil prior to
assembly.
Be careful not to let oil, grease or coolant contact
the timing belt, clutch disc and flywheel.
All removed parts, if to be reused, should be re-
installed in the original positions and directions.
Bolts, nuts and washers should be replaced with
new ones as required.
Even if necessary inspections have been made
in advance, proceed with assembly work while
making rechecks.
Remove or install the engine in an area where
chain hoists, lifting devices, etc. are available for
ready use.
Be sure not to damage coated surfaces of body
panels with tools or stain seats and windows with
coolant or oil. Place a cover over fenders, as re-
quired, for protection.
Prior to starting work, prepare the following:
Service tools, clean cloth, containers to catch cool-
ant and oil, wire ropes, chain hoist, transmission
jacks, etc.
Lift-up or lower the vehicle when necessary.
Make sure to support the correct positions.
