important that air does not leak into
the system as this will affect the
running of the engine. The clips
should be checked for tightness and
the pipes for damage. If a pipe is
damaged be sure to replace it with
one of the correct specification.
Catalytic Converters
Vehicles fitted with catalysts are
designed to have reduced exhaust
emissions. Although the catalysts
require no maintenance, the joints
around them and the wiring to the
heat sensor (Lamba Sensor) must be
kept tight and in good order.
At each service the emissions should
be checked and any adjustments
made. This must be carried out by a
qualified person.
After a period of up to 50,000 miles
the catalyst units may need replacing.
This must be done using the correct
specification obtained from your
Morgan Dealer.
Caution: The catalysts may be
externally hot, as with all exhaust
fittings, DO NOT TOUCH UNTIL COLD.
Warning: Never make modification to
any part of the ignition, injection or
exhaust system. This will affect
emissions and may be illegal.
Vehicles fitted with catalytic converters
must never be driven with a misfire, either
when cold or running. If a misfire
develops this must be examined
immediatley and the vehicle should not
be driven as this may cause fire.
Ignition
Spark Plugs
The spark plugs should be checked
every 5,000 miles for the correct gap.
The electrode and body should be
cleaned and examined for damage. If
the plug shows any sign of damage or
deposits it must be replaced.
When fitting new spark plugs be sure
only the correct specification is used
and the gap correctly set.
Warning: Never carry out work on the
ignition system with the circuits on!
The charges generated by electronic
systems can give severe shocks, and
discharges may damage the controls.
To Remove Plugs
Clean the area around the plugs and
then remove the caps. Do not pull
them by the leads. Carefully remove
the spark plugs with the correct size
spanner. Be sure the spanner will not
damage the plug insulation.
Warning: While the plugs are out, be
certain that no material of any kind
enters the holes!
Set the gap on each plug to the
correct size and clean the insulation.
Fit the plug to the spanner and gently
place into the tube. Tighten the plug
with your fingers or the spanner only.
Do not tighten if there is any
resistance. When the plug is finger
tight, tighten by a maximum of one
quarter turn only. Do not overtighten.
Refit the plug leads in the correct
order.
When checking the plugs, be sure to
examine the leads and caps. If any
damage is found replace with the
correct lead.
Ignition Coils
The ignition coils mounted on the
back of the engine should be checked
at each service for tightness and the
correct fit of the leads.
Warning: Under no circumstances
should any modification be made to
the ignition or the fuel system. The
ignition system fitted to the car needs
no adjustment by the owner.
