valve opens, oil is passed back into the inlet side of pump. From the pump the
pressurised oil flows through the full
- flow filter to the oil gallery. The oil gallery
passes along the right
- hand side of the engine, from where oil is taken to feed the
crankshaft main bearings and through drillings in the webs of the crankshaft to the
big - end bearings. Oil is also token forward along the oil galley to the auxiliary
shaft, then subsequently to the
camshaft bearings and valve gear. Lubrication of the
little end bushes, the gudgeon pins and the non
- thrust sides of the cylinder liners is
by oil mist. A threaded outlet on the oil gallery cover, approximately opposite the
fourth main
beoring, feeds oil to the pressure gauge.
Oil Level
q,
BEFORE checking oil level, allow a full five minutes for oil to return to sump.
The correct level
is to the upper mark on the dipstick, which is located at the right -
hand rear of the oil sump. When checking the oil level the car should be standing on
an even surface and the dipstick withdrawn, wiped, replaced and finally withdrawn
and checked, the depth of the oil on the end of the dipstick indicating the level of
the oil in the sump.
If the addition of oil is necessary, remove the filter cap on the
inlet
camshaft cover and add new engine oil of correct grade (see TECHNICAL DATA)
until the dipstick indicates that the oil in the sump has reached the required level.
Do
NOT overfill. Replace the oil filler cap securely otherwise an oil loss could
occur, with the resultant failure of the entire engine lubrication system. With a new
engine the oil, together with the filter, should be
chonged at the FIRST 500 miles
J/ri
(800 km) and thereafter at EVERY subsequent 5,000 miles (8,000 km) if the oil appears

to be excessively dirty BEFORE this distance has been covered, it should be changed

and a new 011 filter fitted.
