3. If an obvious cause for an observed or reported
concern is found, correct the cause (if possible)
before proceeding to the next step.
CHECK for evidence of oil
leaks on components. Use an
ultraviolet (UV) leak tester if an
oil leak is not evident, INSTALL
new gaskets or components as
required.
CHECK the coolant expansion
tank for a film of oil on the
coolant surface. INSTALL a
new oil cooler or oil cooler
gasket.

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:
