Some Vehicles Equipped With A 6.0l Diesel Engine May Exhibit White Smoke, Black Smoke, Lacks Power, Exhaust Odor, Surges, Or No Start As A Result Of Excessive Coking Deposits (un-combusted Or Incompletely Combusted Hydrocarbons), The Root Cause Of The Coking Must Be Corrected Or The Coking May Reoccur. This Tsb Is To Be Used Only If One Or More Of The Components Listed Below In The Service Procedure Have Already Been Identified As Having An Excessive Coking Condition. After Following Normal Powertrain Controls/emissions Diagnosis (pc/ed) Diagnostics, Use This Tsb To Identify The Root Cause Of The Excessive Coking Condition.
