The level of oil in the engine crankcase should be in register
with the mark "Ï" on oil dipstick 3 (Fig. 20). Measure the oil
level 2-3 min after shutting down a warmed-up engine.
Drain oil from the engine crankcase right after the end of the
trip when the oil is still hot. This insures rapid and complete
drainage of oil.
For removing the oil filter 10 (Fig. 21), rotate it counter-
clockwise. When installing a new filter, make sure, that the
rubber sealing ring is in serviceable condition, lubricate it with
motor oil, and screw in the filter by hand till the sealing ring
would contact with the cylinder block surface, then draw up tight
the filter through 3/4 of turn. Make sure, that there is no leakage
of oil.
Oil pressure in the lubrication system of a warmed-up engine
of a new automobile at a speed of 60 km/h in direct gear and
when the oil cooler cock is open should be at least 343 kPa (3.5
kgf/cm
2
). Oil pressure in a cold engine can be increased to 588
kPa (6kgf/cm
2
), and on a hot summer day it could be dropped
to 294 kPa (3kgf/cm
2
). Stop running the engine, when oil
pressure is dropped to 118 kPa (1.2kgf/cm
2
).
