PROBLEM SYMPTOMS TABLE (FOR YOUR INFORMATION)
ItemsSymptom
StartingWon’t startThe starter is used to crank the engine, but there is no combustion within the
cylinders, and the engine won’t start.
Fires up and diesThere is combustion within the cylinders, but then the engine soon stalls.
Hard startingEngine starts after cranking a while.
Idling
stability
HuntingEngine speed doesn’t remain constant; changes at idle.
stability
Rough idleUsually, a judgement can be based upon the movement of the tachometer
pointer, and the vibration transmitted to the steering wheel, shift lever, body, etc.
This is called rough idle.
Incorrect idle speedThe engine doesn’t idle at the usual correct speed.
Engine stall
(Die out)The engine stalls when the foot is taken from the accelerator pedal, regardless
of whether the vehicles is moving or not.
Engine stall
(Pass out)The engine stalls when the accelerator pedal is depressed or while it is being
used.
DrivingHesitation Sag“Hesitation” is the delay in response of the vehicle speed (engine speed) that
occurs when the accelerator is depressed in order to accelerate from the speed
at which the vehicle is now traveling, or a temporary drop in vehicle speed
(engine speed) during such acceleration.
Serious hesitation is called “sag”. (Refer to Fig. 1)
Poor accelerationPoor acceleration is inability to obtain an acceleration corresponding to the
degree of throttle opening, even though acceleration is smooth, or the inability
to reach maximum speed.
StumbleEngine speed increase is delayed when the accelerator pedal is initially
depressed for acceleration. (Refer to Fig. 2)
ShockThe feeling of a comparatively large impact or vibration when the engine is
accelerated or decelerated.
SurgeThis is repeated surging ahead during constant speed travel or during variable
speed travel.
KnockingA sharp sound like a hammer striking the cylinder walls during driving and which
adversely affects driving.
StoppingRun on
(“Dieseling”)The condition in which the engine continues to run after the ignition switch is
turned to “LOCK” (OFF) position. Also called “Dieseling”.

Install the gasket so that its print part can face towards the
oil pan side.
INSPECTION
Check the following points; replace the part if a problem is
found.
1. EXHAUST MANIFOLD CHECK
(1) Check for damage or cracking of any part.
(2) Using a straight edge and a feeler gauge, check for
distortion of the cylinder head installation surface.
Standard value: 0.15 mm or less
Limit: 0.20 mm
2. TURBOCHARGER ASSEMBLY CHECK
(1) Visually check the turbine wheel and the compressor
wheel for cracking or other damage.
(2) Check whether the turbine wheel and the compressor
wheel can be easily turned by hand.
(3) Check for oil leakage from the turbocharger assembly.
(4) Check whether or not the waste gate valve remains open.
If any problem is found, replace the part after disassembly.
