DESCRIPTION
 Some customers may experience white/blue smoke from the exhaust pipes after long idle periods or while driving at slow speeds in heavy traffic. When engine oil viscosity is low due to improper oil change intervals and/or usage of low viscosity oil, and the internal pressure of the crank case is greater than the exhaust pressure while idling, the lubrication oil for the turbine shaft gets into the exhaust side of the turbine and creates smoke by heat of the turbine/catalyst converter

Customers having this concern should have their vehicle repaired according to the following reapair procedure. 

NOTE: The oil change program as described in the prior published service bulletin under the same subject, is no longer in effect. Vehicles having their turbochargers replaced during the procedures as described in this service bulletin, will NOT require any further repairs related to this service bulletin or any future revisions. 

INSPECTION PROCEDURE
If the proper oil change intervals using 5W-30 have been preformed, repair the vehicle using the following repair procedure.
