303-00-5 Engine System - General Information 303-00-5
DIAGNOSIS AND TESTING
Symptom
Oil consumption
Possible Sources Action
Use of the wrong type of
engine oil.
Faulty positive crankcase vent-
ilation (PCV) system.
- Hoses or ventilation or
breather valves are blocked.
This causes excessive
pressure in the crankcase
which causes more oil to
enter the combustion
chamber.
- PCV oil separator is faulty
and engine oil can enter the
combustion chamber
through the intake manifold.
Turbocharger seals (diesel
engine only).
DETERMINE the last type of
engine oil used and compare
with the specification. Change
the engine oil to the specifica-
tion.
CHECK if the PCV system is
operating correctly and repair
as necessary. REFER to:
