Wells 6P1378 PCV Valve Positive Crankcase Ventilation Valve

The Wells 6P1378 is a direct-fit replacement Positive Crankcase Ventilation (PCV) Valve engineered to restore proper crankcase ventilation to your engine. Also sold under the WVE by NTK brand label, this valve is manufactured to meet or exceed OE specifications for fit, form, and function.

The PCV valve is a critical component of the crankcase ventilation system. It reliably routes exhaust air and crankcase gases back through the engine intake to be re-burned, reducing harmful emissions and protecting the engine from pressure buildup. A failing PCV valve can lead to sludge formation, oil leaks, rough idle, and accelerated engine wear.

• Meets or exceeds OE specifications for fit, form, and function
• Precision-engineered for consistent flow control and reliable sealing
• Built with premium materials for long service life
