When engine is first installed, provide the proper quantity
of
oil as indicated under “specifications” section. The oil
cap is located on top of engine rocker cover. After pouring in oil, it will be necessary to wait several minutes before
the oil level is checked in order to allow time for oil to flow to sump. Another fill cap which leads directly
to
sump
is located on sump near front of engine. Run engine for several moments, shut down and check level on dipstick
(see Fig.
If oil level measurement is different from the “full” mark on dipstick, a new mark should be scratched
or filed at the correct level. Another method
is to measure the distance between the new full level and the factory
full mark on the dip stick, remove the dipstich tube from the sump, and cut that distance
off the tube. After deburring
and reinstalling the tube the dipstick will be lowered into the oil, thereby retaining the factory markings. Of course,
the above procedure applies only to
6
cylinder N.A. and turbo units with disptick at front of sump. Four cylinder
models with stick at rear of sump, require scratching the appropriate marks. These procedures are necessitated
by differing installation angles.
When measuring oil level in regular usage in all naturally aspirated engines it is preferable to check after the engine
has stopped for a period of time, such as overnight. This allows the oil in the overhead valve system to drain back
to the oil sump, permitting a more accurate measurement.
On all turbocharged engines the oil should be checked prior
to
starting. After several minutes, shut engine down,
wait for oil to drain back for several minutes, then check and add as required.
Add engine oil of the type and viscosity as follows. Oil should meet Ford specification
API
classification CC or equivalent.

TURBO
ENGINES: API classification CD oils only must be used in turbocharged engines. Use of other oil result
in reduced engine life and invalidate engine warranty.
Serious damage to turbocharger may result from inadequate lubrication. Upon starting, engine should be allowed
to idle (1000 rpm maximum) for 30 seconds or more before applying load. Also allow engine to idle for at least two
minutes before shut-down to dissipate heat from turbocharger bearings.
Turbocharger must be oil-primed under any one of the following conditions;
After an oil change.
If oil supply tube to turbocharger has been disconnected.
If either the engine or turbocharger is newly installed.
If
no oil pressure registers on gauge after a “dead
(cranking with stop control in operation) for 15 seconds.
This test must be performed if engine has not been started for 4 weeks or more.
To
oil-prime turbocharger;
a) Check for sufficient oil in the engine sump but
do
not top-up at
this time.
b)
Remove plug on top of turbo oil feed block, inject
pint of oil and replace plug.
c) Using suitable syringe, inject about
4
pints of oil (as used in engine sump) into oil gauge connection for engine.
d) Start engine, allowing
1
minute to idle before increasing speed.
e) Stop engine and check sump oil level. Top-off if needed or drain off any surplus.
Refit oil gauge.
