SITUATION
After replacing the short engine, the new or remanufactured engine may exhibit one of the following complaints:
^ Increased oil consumption
^ A whistling noise can be heard from the front or rear crankshaft seals
^ The Service Engine Soon lamp is illuminated with various adaptation faults
CAUSE
The new or remanufactured engine is fitted with a cylinder bank 1-4 valve cover not equipped with a crankcase ventilation valve. This new valve cover is optimized to eliminate freezing in colder climates. The vehicle was not equipped with the updated hose or hoses with an external crankcase ventilation valve as directed in the current version of EPC.
Cylinder Head Cover Identification:
The new optimized cylinder 1-4 head cover without the integrated crankcase ventilation valve.
The older production cylinder 1-4 head cover with the integrated crankcase ventilation valve.
CORRECTION
Install an insulated crankcase ventilation hose with an external pressure regulating valve. Refer to one of the procedures outlined below, based on model and production date.
