Filing in context

Defect
In the crankcase ventilation system, the PCV valve is made of an inappropriate material, resulting in insufficient durability at the crankcase connection. If the connection fails, engine oil enters the combustion chamber and burns, producing large amounts of white smoke from the muffler. In the worst case, the engine may stall while driving.
Corrective action
On all vehicles, replace the PCV valve with a corrected part.
