2 Engine oil and filter
1
1 The engine oil level should be checked at
the weekly service (see “Routine
Maintenance”). Preferably check the level
cold, first thing in the morning or if the engine
has been running, allow at least ten minutes
to elapse after switching off to permit the oil to
drain.
2 Withdraw the dipstick, wipe it clean on
non-fluffy material, re-insert it and then
withdraw it for the second time (photo).
3 The oil level should be between the MIN
and MAX marks. If not, top up with specified
oil to the MAX mark. Pour the oil slowly
through the filler orifice on the rocker cover.
To raise the oil level from MIN to MAX will
require approximately 1.1 litre (2.0 pints)
(photos).
4 At the intervals specified in “Routine
Maintenance” the oil and filter should be
renewed.
5 Have the engine at normal operating
temperature, remove the oil filler cap.
6 Place a suitable container under the sump
pan. Unscrew and remove the oil drain plug
and allow the oil to drain (photo).
7 While the oil is draining, unscrew and
discard the oil filter. To unscrew the filter, a
filter or chain wrench will normally be
required. If such a tool is not available, drive a
long screwdriver through the oil tester casing
and use it as a lever to unscrew the filter
cartridge.
8 Smear the rubber sealing ring of the new oil
filter with oil and screw into position using
hand pressure only (photo).
9 Refit the drain plug and refill the engine with
the correct quantity and grade of oil.
10 Start the engine. It will take two or three
seconds for the oil warning lamp to go out.
This is normal and is due to the time taken for
the new filter to fill with oil.
11 Switch off, check for leaks and check the
oil level, topping up if necessary.
3 Crankcase ventilation
system
1
1 This system is designed to draw oil fumes
and blow-by gas (which has passed the piston
rings) from the crankcase and draw it into the
intake manifold when it will then be burned
during the normal combustion process.
2 Regularly check the security of the system
hoses which run from the rocker cover or
crankcase breather unit (photo).
3 Periodically, detach the hoses and clean
them out with paraffin and a brush or rag pull
through.
4 Evidence of sludge or emulsified oil within
the hoses or inside the oil filler cap will
indicate that the engine is running too cool
particularly if the car is used mainly for short
journeys where the engine never reaches full
working temperature.
4 Major operations possible
