What It Helps Address

• Crankcase ventilation flow problems caused by a worn PCV valve
• Excessive oil vapor buildup in the engine crankcase
• Rough idle related to PCV system restriction
• Vacuum-related drivability concerns tied to PCV wear
• Emission control service needs on GM truck and performance applications

Installation Notes and Tips

Verify the hose routing, nipple angle, and connector style before installation. This V334 uses a push-on attachment with no electrical connector, so it should be matched to the original PCV valve configuration on the vehicle. For 1999-2003 Chevrolet Corvette, w/o Tube, and 1999-2002 Chevrolet Camaro, w/o Tube, confirm the tube is not present before ordering.
