INSULATOR-PCV VALVE (Mitsubishi MB1G182-70F00)

MB1G182-70F00: A damaged PCV valve insulator can allow unfiltered air to enter the crankcase ventilation system. This aftermarket replacement part references Mitsubishi as the OE maker and carries the cross-reference number MB1G182-70F00. The insulator functions as a thermal barrier between the PCV valve and its mounting point. A common failure consequence is a vacuum leak that disrupts air-fuel mixture balance. During a routine check, a cracked or brittle insulator may cause rough idling or increased emissions. Verify the serial number or application, then call (562) 693-7748.
