Viton
In common with many other manufacturers
vehicles, some components have O-rings, seals
or gaskets, which contain a material known as
'Viton'.
Viton is a fluoroelastomer, that is a synthetic rubber
type material, which contains Fluorine. It is
commonly used for O-rings, gaskets and seals of
all types. Although Viton is the most well known
fluoroelastomer, there are others, including
Fluorel
and Tecmoflon.
When used under design conditions
fluoroelastomers are perfectly safe. If, however,
they are exposed to temperatures in excess of
400°C, the material will not burn, but will
decompose, and one of the products formed is
hydrofluoric acid.
This acid is extremely corrosive and may be
absorbed directly, through contact, into the general
body system.
O-rings, seals or gaskets which have been exposed
to very high temperatures will appear charred or
as a black sticky substance.
DO NOT; under any circumstances touch them or
the attached components.
Enquiries should be made to determine whether
Viton or any other fluoroelastomer has been used
in the affected O-ring, seal or gasket. If they are of
natural rubber or
nitrile there is no hazard. If in
doubt, be cautious, as the material may be Viton
or any fluoroelastomer.
If Viton or any other fluoroelastomers have been
used, the affected area should be decontaminated
before the commencement of work.
Disposable heavy duty plastic gloves should be
worn at all times, and the affected area washed
down using wire wool and a limewater (calcium
hydroxide) solution to neutralize the acid before
disposing of the decomposed Viton residue and
final cleaning of the area. After use, the plastic
gloves should be discarded carefully and safely. This process may cause particles of molten metal
to
be emitted at a high velocity, and the eyes and
skin must be protected.
Arc Welding
This process emits a high level of ultra-violet radiation, which may cause arc-eye, and skin burns
to the operator and to other persons nearby.
Gas-shielded welding processes are particularly
hazardous in this respect. Personal protection must
be worn, and screens used to shield other
~eo~le. . .
CONTACT LENS WEARERS ARE ADVISED TO
REVERT TO ORDINARY SPECTACLES WHEN
ARC WELDING as the arc spectrum is believed to
emit microwaves which dry out the fluid between
the lens and the eye. This may result in blindness
when the lens is removed from the eve.
Metal spatter will also occur, and appropriate eye
and skin protection is necessary.
The heat of the welding arc will produce fumes and
gases from the metals being welded, the rods and
from any applied coatings or contamination on the
surfaces being worked on. These gases and fumes
may be toxic and inhalation of these should be
avoided. The use of extraction ventilation to remove
the fumes from the working area may be necessary
particularly in cases where the general ventilation
is poor, or where considerable welding work is
anticipated. In extreme cases or confined spaces
where adequate ventilation cannot be provided,
air-fed respirators may be necessary.
Gas Welding (and Cutting)
Oxy-acetylene torches may be used for welding
and cutting, and special care must be taken to
prevent leakage of these gases, with consequent
risk of fire and explosion.

and skin protection is necessary.

303-00-5 Engine System - General Information 303-00-5
DIAGNOSIS AND TESTING
Symptom
Oil consumption
Possible Sources Action
Use of the wrong type of
engine oil.
Faulty positive crankcase vent-
ilation (PCV) system.
- Hoses or ventilation or
breather valves are blocked.
This causes excessive
pressure in the crankcase
which causes more oil to
enter the combustion
chamber.
- PCV oil separator is faulty
and engine oil can enter the
combustion chamber
through the intake manifold.
Turbocharger seals (diesel
engine only).
DETERMINE the last type of
engine oil used and compare
with the specification. Change
the engine oil to the specifica-
tion.
CHECK if the PCV system is
operating correctly and repair
as necessary. REFER to:

DIAGNOSIS AND TESTING
Monitors
The purpose of the monitors is to continuously
check the operation of the emission related sensors
and actuators. It then establishes if they are
operating within specified tolerances. All monitors
carry out their functions in such a way as to be
unnoticeable by the driver of the vehicle. Each one
is carried out under specific conditions of load,
speed and engine temperature. The Comprehensive Component Monitor, Combustion
Misfire Monitor and
AirIFuel Ratio Monitor operate
continuously. The remaining monitors are only
invoked under certain operating conditions. On
diesel variants, all of the monitors operate under
normal driving conditions: There are no monitors
which intervene and cause special operating
modes to enable the monitors to work. Some diesel
monitors are non-continuous. This means that in
a drive cycle, monitoring is done as and when
suitable driving conditions exist and potential faults
are accumulated and compared with acceptance
criteria. Examples of this type are the turbocharger
boost pressure and exhaust gas recirculation
(EGR) monitors on vehicles with common rail fuel
injection.
( Comprehensive Component Monitor (CCM)
When the CCM detects a component operating out
of tolerance, it sets a Diagnostic Trouble Code
(DTC), which is stored in the EEPROM. If the same
concern is confirmed during the next trip the MIL
will be switched on. The CCM monitors many
components, sub-systems and signals. The
following is a list of those that can effect emissions
depending on application:
Electronic Ignition (El) System.
Crankshaft Position (CKP) Sensor.
Ignition Coil.
Electronic Throttle Control Unit.
Camshaft Position (CMP) Sensor.
Air Conditioning
(AIC) Clutch.
Idle Air Control (IAC) Valve.
Mass Air Flow (MAF) Sensor.
Manifold Absolute Pressure (MAP) Sensor.
Intake Air Temperature (IAT) Sensor.
Engine Coolant Temperature (ECT) Sensor.
Cylinder Head Temperature (CHT) Sensor.
Heated Oxygen Sensor
(H02S).
Catalyst Monitor Sensor.
Charge Air Temperature Sensor.
Knock Sensor (KS).
Throttle Position (TP) Sensor.
Vehicle Speed Sensor (VSS).
Boost Pressure Sensor.
Cam-Crank Phasing Sensor.
EEPROM.
High Pressure Fuel Injection Pump.
Exhaust Gas Recirculation (EGR) Valve Monitor.
Fuel Injectors.
Turbocharger.
Combustion Noise Monitor.
Barometric Pressure (BARO) Sensor.
Combustion Misfire Monitor (All except vehicles
with diesel engine)
The combustion misfire monitor operates independently of the others, and can detect misfires
caused by the ignition system, fuel system or
mechanical engine components. As each cylinder
fires, a characteristic crankshaft acceleration is
produced. The monitor detects irregularities in the
acceleration pattern using the crankshaft position (CKP) sensor, thus detecting the misfire. It can
also detect which cylinder has misfired.
Combustion misfires can be categorized as follows:
Type
A: These can cause catalytic converter
damage due to excessive internal temperatures.
If a certain number of misfires occur over a
pre-determined number of engine revolutions, the
MIL will be switched on to alert the driver of the
concern.
Type B: These can lead to an increase in emissions
to a point above the EOBD threshold. If the misfire
is detected during a second trip, over a,
pre-determined number of engine revolutions, the
MIL will be switched on. If the misfire does not
occur over the next three trips, the MIL will be
extinguished
AirIFuel Ratio (AFR) Monitor (All except vehicles
with diesel engine)
The H02S fitted before the catalytic converter
(upstream) measures the oxygen content of the
exhaust gas and the variations in it. This then
enables the PCM to adjust the opening times of
the fuel injectors to maintain the correct AFR. This
is known as Short Term Fuel Trim (STFT). If the
same variation is registered a pre-determined
number of times, a permanent correction factor is
applied. This is known as Long Term Fuel Trim
(LTFT), which is stored in the EEPROM. When the
correction factors exceed pre-determined limits a
DTC will be set in the EEPROM. If a concern is
