Condition
Some customers may comment on excessive oil consumption or blue smoke on acceleration. Excessive oil consumption, not due to leaks, is the use of
0.9L (1 qt) or more of engine oil within 3200 km (2,000 mi).
Cause
Incorrect sizing of the PCV orifice and/or misalignment of the oil baffle in the cam cover may allow higher than desired amounts of oil into the
combustion chamber.
Correction
Important:
If the following information in this bulletin does not resolve the concern, refer to Oil Consumption Diagnosis in the appropriate Service
Information (SI) procedures.
Inspect the cam cover for heat stake marks and inspect the intake manifold for PCV orifice size. Replace either, as necessary, based on
inspection. Follow the procedures below.
