Genuine 946-107-229-77 Crankcase Vent Valve for Porsche

The Genuine 946-107-229-77 Crankcase Vent Valve is an OEM replacement component designed to maintain proper crankcase pressure and emissions control in your Porsche. This valve is a critical part of the positive crankcase ventilation (PCV) system, which recirculates blow-by gases from the crankcase back into the intake system for combustion, reducing harmful emissions and preventing oil contamination.

Key Features:

• Genuine Porsche OEM quality for reliable performance and exact fit
• Maintains optimal crankcase pressure and ventilation
• Helps reduce engine emissions and meet environmental standards
• Direct replacement for worn or failed crankcase vent valves
• Designed for right-side installation on applicable engines

Installation Note: This valve requires two O-rings for proper installation: (1) 999-707-677-40 O-ring and (1) 999-707-677-41 O-ring (sold separately).

When crankcase vent valves fail, they can cause rough idle, increased oil consumption, and check engine lights. Replacing a faulty valve with this genuine OEM component restores proper engine ventilation and performance.
