Gates PCV Valve Engine Crankcase Ventilation Valve

The Gates PCV valve (positive crankcase ventilation valve) is an engine crankcase ventilation valve. It regulates the flow of crankcase vapors, also called blow-by gases, from the crankcase back into the intake system to be burned in combustion. This helps control harmful emissions and reduces pressure build-up inside the engine.

Key Features:

• Meters crankcase vapor flow to suit changing engine operating conditions
• Helps reduce crankcase pressure and limit oil contamination and sludge formation
• Supports emissions control by recirculating blow-by gases into the intake
• Helps prevent oil leaks and seal damage caused by excess crankcase pressure
• Built to meet or exceed original equipment performance expectations
• Backed by Gates, a respected name in belts, hoses, and engine management components

A working PCV valve helps keep your engine running smoothly and efficiently. A stuck or clogged valve can cause rough idle, oil consumption, leaks, or sludge. Replacing it as part of routine maintenance helps protect engine life and emissions system performance. Select the individual listing for the exact part number you need.
