Vent Breather Pipe.

The Vent Breather Pipe is a OE MATCH component designed for the engine’s crankcase ventilation (PCV) system. This breather pipe routes crankcase vapours and excess pressure from the engine to the air/oil separator or intake system, helping maintain proper internal engine pressure and emissions control. It ensures correct fitment, reliable sealing, and long-term durability on Porsche 957 Cayenne S / GTS 4.8L models.

Fits:

  • Porsche 957 Cayenne S/GTS 4.8L 2007-10

Diagram Ref No 10 (Diagram Ref No 11 And 12 Included)

What This Product Does:
  • Vents excess crankcase pressure created during engine operation.
  • Routes blow-by gases and oil vapours to the PCV/air-oil separator system for proper ventilation.
  • Helps reduce stress on engine seals and gaskets by preventing pressure build-up.
  • Supports proper emissions control by returning vapours into the intake system rather than releasing them.

Symptoms Of Wear Or Failure:
  • Cracks or splits in the breather pipe can cause a vacuum leak, leading to rough running or unstable idle.
  • A leaking breather pipe can trigger engine management faults related to vacuum system leaks, PCV system performance, air/fuel mixture imbalance.
  • If crankcase pressure is not vented correctly, it can push oil past seals and gaskets, causing leaks.
  • Oil vapours escaping from a damaged breather pipe may cause an oily smell in the engine bay.
  • Symptoms may include oil filler cap difficult to remove, whistling/hissing noises, pressure-related seal issues.
  • Breather pipes often fail due to age and heat, showing hardened plastic/rubber, cracking, broken fittings or connectors.
  • If ventilation is disrupted, oil vapour can be drawn into the intake incorrectly, contributing to oil burning.

Why Replacement Matters:
  • Prevents vacuum leaks, which can cause rough idle, poor performance, and fault codes.
  • Maintains proper crankcase ventilation, preventing pressure build-up inside the engine.
  • Helps prevent oil leaks, since excessive crankcase pressure can force oil past seals and gaskets.
  • Protects engine performance and efficiency, by keeping the air/fuel mixture stable and reducing unmetered air entering the system.
  • Reduces risk of secondary damage, such as damaged seals, intake contamination, or long-term PCV system issues.

With age and heat cycles, coolant hoses can weaken, crack or develop internal swelling. A compromised hose may cause coolant leaks, overheating, reduced engine performance or complete cooling system failure. Replacing a worn hose with a high-quality alternative ensures the V8 Cayenne continues to run cool, efficient and trouble-free.

What This Coolant Hose Does

This specialised coolant hose:

  • Transfers coolant between key cooling components
  • Maintains optimal engine temperature under load
  • Helps prevent overheating during towing or spirited driving
  • Supports proper coolant circulation in V8 Cayenne engines
  • Seals securely to avoid leaks and pressure loss

A healthy coolant hose is essential for maintaining engine reliability, especially in high-output S, GTS and Turbo variants.

Why Coolant Hoses Fail on Porsche Cayenne V8 Engines

Typical issues include:

  • Heat-induced rubber degradation from repeated thermal cycles
  • Cracking or splitting caused by age and vibration
  • Internal hose collapse, restricting coolant flow
  • Coolant contamination, accelerating material breakdown
  • Pressure spikes from failing thermostats or caps
  • Exposure to oil, which weakens hose material

Symptoms of failure may include coolant smells, visible drips, overheating warnings, or low coolant levels.

Why You Should Replace a Faulty Coolant Hose

Replacing a worn coolant hose provides:

  • Restored coolant pressure and circulation efficiency
  • Prevention of leaks and overheating
  • Protection of sensitive engine components
  • Reduced risk of roadside breakdowns
  • Improved long-term reliability for engines

Given the high engine bay temperatures in Cayenne, S, GTS and Turbo models, replacing hoses proactively is a smart preventative step.

About Engine Block Hoses

Engine Block Coolant Hoses – Front Engine Porsche Models | Reliable Cooling for Peak Performance

Engine block coolant hoses are critical to maintaining stable engine temperatures and preventing overheating in your Porsche’s front-engine cooling system. These hoses circulate coolant between the engine block, radiator, and heater core, ensuring consistent temperature regulation and efficient heat dissipation — essential for performance, reliability, and longevity.

At Design911, we supply a complete selection of genuine and manufacturer-quality engine block coolant hoses for front-engine Porsche models, including the transaxle models, Cayenne, Panamera, and Macan. Each hose is precisely engineered for a perfect fit and superior heat resistance, offering the same durability, flexibility, and performance as factory-installed components.

What Do Engine Block Coolant Hoses Do?

Coolant hoses in the engine block are responsible for transferring coolant throughout the engine’s cooling circuit. Their main functions include:

  • Carrying coolant between the radiator, water pump, and engine block.
  • Regulating engine temperature for efficient performance.
  • Maintaining system pressure within the cooling system.
  • Preventing heat build-up that can lead to overheating or gasket failure.

Properly functioning coolant hoses are essential for ensuring your Porsche’s front-mounted engine operates within optimal temperature ranges — especially during heavy use or long drives.

Why Do Engine Block Coolant Hoses Fail?

Due to constant exposure to heat, pressure, and coolant chemicals, these hoses naturally degrade over time. Common causes of failure include:

  • Heat damage from prolonged exposure to high engine temperatures.
  • Rubber deterioration or cracking from age and coolant corrosion.
  • Leaks at joints or clamps due to pressure fluctuations.
  • Swelling or soft spots from internal chemical breakdown.
  • Mechanical abrasion from contact with nearby components.

Symptoms of failing hoses include visible coolant leaks, overheating, low coolant levels, or a strong coolant smell from the engine bay.

Why Replace Faulty Engine Block Coolant Hoses?

A leaking or weakened hose can cause serious cooling system failures, including overheating and engine damage. Replacing old or brittle hoses ensures reliable coolant circulation and safeguards your Porsche’s engine performance.

Benefits of replacement include:

  • Restored cooling efficiency and pressure control.
  • Prevention of leaks and overheating.
  • Improved long-term reliability and system safety.
  • Manufacturer-quality materials for perfect fit and heat resistance.

All replacement hoses in this range are constructed using reinforced, high-grade rubber compounds that meet or exceed factory standards, ensuring durability and dependability in all driving conditions.
