Kenworth excessive engine crankcase pressures may cause the 90-degree elbow of the vent tube assembly to detach from the crankcase ventilation breather, possibly allowing engine oil to come into contact with hot surfaces.
The short version
PACCAR Incorporated reported a problem with the engine and engine cooling engine. Here is what owners need to know.
Excessive engine crankcase pressures may cause the 90-degree elbow of the vent tube assembly to detach from the crankcase ventilation breather, possibly allowing engine oil to come into contact with hot surfaces.
If engine oil comes into contact with a hot surface, there is an increased risk of a fire.
Cummins will notify owners on behalf of PACCAR, and Cummins service centers will administer the repairs which include securing the ends of the 90-degree elbow and reprogramming the electronic control module (ECM) with software that can adjust the engine output under misfire conditions to limit crankcase pressures, free of charge.
