When driving the automobile, watch the functioning of the
oil pressure transmitters. The low oil pressure warning transmit-
ter must operate at an oil pressure drop in the system down to
39-78 kPa (0.4-0.8 kgf/cm
2
).
The low oil pressure warning lamp may light when the hot
engine is running at an idling speed, but the lamp must go out
immediately with an increasing crankshaft speed.
Immediately stop running the engine if some faults in the engine
lubrication system are detected.
Maintenance of the Crankcase Ventilation System
For flushing and cleaning, remove the vacuum regulator
from the engine and disassemble it. Clean the pipelines (Fig. 27),
the calibrated orifice "b" (Fig. 28) and flush the parts of the
vacuum regulator.
Check tightness between the case and cover plate when
assembling the vacuum regulator.
