Hazard

In the blow-by gas recirculation device, certain units have insufficient durability at the crankcase connection due to inappropriate material selection of the PCV valve. As a result, damage to this connection may allow engine oil to enter the combustion chamber, causing combustion that produces excessive white smoke from the muffler. In severe cases, the engine may stall while driving.
