Bleeder Valve, Intake Manifold. Porsche 955 Cayenne 3.2L V6 2004-06  ❭  95560551701

Bleeder Valve, Intake Manifold.

The Bleeder Valve, Intake Manifold is an important emissions and crankcase ventilation system component designed to regulate vacuum pressure within the intake manifold and associated engine breathing systems. Often referred to as a pressure regulating valve or breather valve, it helps control airflow between the intake system and crankcase ventilation circuits, ensuring stable engine operation and efficient combustion.

Fits:

• Porsche 955 Cayenne 3.2L V6 2004-06

Diagram Ref No 20

Manufactured to OEM specifications, the bleeder valve is engineered to maintain correct vacuum levels, support proper crankcase ventilation, and optimise engine performance. It plays a vital role in reducing emissions, preventing excessive pressure build-up, and ensuring smooth engine operation under varying load conditions.

What This Product Does:

• Regulates vacuum pressure within the intake manifold system
• Supports proper crankcase ventilation operation
• Controls airflow between engine ventilation circuits and the intake system
• Helps maintain stable idle and engine performance
• Reduces harmful emissions by managing crankcase gases
• Supports efficient combustion and engine management system operation

Symptoms Of Wear Or Failure:

• Rough or unstable idle
• Check engine light illumination
• Vacuum leaks and hissing noises from the engine bay
• Increased oil consumption
• Poor engine performance or hesitation
• Engine misfires Excessive crankcase pressure
• Fault codes relating to air leaks, fuel trim, or crankcase ventilation systems

Why Replacement Matters:

• Restores proper intake manifold vacuum regulation
• Ensures efficient crankcase ventilation system operation
• Improves idle quality and engine smoothness
• Helps reduce emissions and maintain fuel efficiency
• Prevents excessive crankcase pressure build-up
• Reduces the likelihood of vacuum leaks and engine management faults
• Protects seals and gaskets from pressure-related damage
• Maintains reliable engine performance and long-term engine health
