    Diagram ref no 34

    Required Quantity

1 per engine for the selected cylinder-bank gasket.

What Is This Part?

The head gasket sits between the cylinder head and engine block. It seals combustion gases, oil and coolant at this joint, keeping their respective passages separated. Correct sealing depends on the gasket, mating surfaces and cylinder-head bolt clamping working together. It is renewed when the cylinder head is removed for repair. 

What Does This Part Do?

  • Seals combustion pressure: Closes the joint around the cylinders.
  • Seals fluid passages: Helps retain oil and coolant where they pass between the block and head.
  • Separates circuits: Helps prevent leakage between combustion chambers and fluid passages. 

    Why Replace This Part?

Overheating, distorted mating surfaces or incorrect bolt tightening can damage the seal. Replacing the gasket must therefore include investigating the original cause, not just changing the sealing component. 

During head repairs, check surface condition and flatness, and follow the engine-specific tightening procedure. An unresolved cooling fault or damaged sealing surface can undermine the replacement. 

When to Replace This Part?

  • Confirmed leakage: Testing identifies leakage through the cylinder-head joint.
  • Fluid contamination: Oil and coolant mixing warrants investigation before ordering parts.
  • Compression concerns: Low or uneven readings require diagnosis to distinguish gasket leakage from other engine faults.
  • Overheating damage: Inspection finds a damaged gasket or distorted sealing surfaces.
  • Head removal: Renew the disturbed gasket during reassembly.

    Where Is This Part Fitted?

Location: Between the engine block and the cylinder head on the selected bank of the 4.8L V8. Reference 94810417305 covers cylinders 1–4; reference 94810417405 covers cylinders 5–8.

FAQs

  • Can I reuse the old head gasket?
    Fit a new gasket when reassembling the cylinder-head joint.
  • What else should be checked during replacement?
    Check mating surfaces, cylinder-head bolts and the cooling system, following the engine-specific repair instructions. 
  • Does coolant loss prove the head gasket has failed?
    No. Establish the leak source and check other cooling-system components before committing to cylinder-head work.

About Cylinder Head / Camshaft Carrier

Precision Cylinder Head & Camshaft Covers – Engine Protection and Performance for Porsche Models

The cylinder head and camshaft covers play a vital role in protecting key engine components such as the valvetrain, camshafts, and cylinder head from dirt, debris, and oil contamination. Beyond protection, they ensure proper oil sealing and ventilation — maintaining consistent lubrication and pressure balance within the engine.

At Design911, we offer a wide selection of precision-engineered cylinder head and camshaft covers for both classic and modern Porsche engines. Crafted from high-grade aluminium, magnesium, and composite materials, these covers provide a perfect fit and long-lasting reliability while maintaining the clean, professional look expected from Porsche’s performance heritage.

Whether you’re restoring an air-cooled 911 or servicing a high-output 992, our manufacturer-quality components ensure leak-free operation and exceptional durability.

What Do Cylinder Head and Camshaft Covers Do?

These components serve as the protective shell for your engine’s valvetrain and upper oil channels. They keep contaminants out, manage internal pressure, and help maintain consistent lubrication.

Core Functions:

  • Seal the upper engine area, preventing oil leaks and contamination.
  • Protect the camshafts and valve train from debris and moisture.
  • Regulate crankcase ventilation, supporting optimal engine breathing.
  • Maintain correct oil flow for cooling and lubrication efficiency.

They are essential not only for reliability but also for maintaining the visual and mechanical integrity of your Porsche’s engine bay.

Why Do Cylinder Head / Camshaft Covers Fail?

Over time, heat, pressure, and oil exposure can degrade materials, seals, and gaskets. These issues can lead to leaks, poor ventilation, and even oil starvation in extreme cases.

Common Causes of Failure Include:

  • Cracked or warped covers from repeated heat cycles.
  • Degraded seals or gaskets, causing oil leaks.
  • Loose or fatigued fasteners, leading to uneven sealing pressure.
  • Blocked breather passages, increasing internal pressure.
  • Corrosion or contamination in older engines.

Replacing worn covers and seals restores oil control, prevents leaks, and preserves long-term engine health.

Why Replace with Precision-Engineered Covers?

Upgrading or replacing your covers ensures your Porsche engine operates as intended — leak-free, properly ventilated, and visually clean.

Key Benefits:

  • Restores sealing performance and eliminates oil leaks.
  • Protects vital valvetrain components from dirt and debris.
  • Maintains proper crankcase pressure and oil control.
  • Crafted from premium materials for superior heat and corrosion resistance.
  • Perfect fitment and finish, ensuring long-term reliability.
  • Compatible with a wide range of Porsche models, from classics to modern GT cars.

Precision covers also contribute to the engine’s aesthetic, maintaining the refined look Porsche owners expect.

Highlights:

  • High-strength cylinder head and camshaft covers for Porsche engines.
  • Precision-machined sealing surfaces for long-term oil-tight performance.
  • Manufacturer-quality materials – aluminium, magnesium, and composite options.
  • Improved oil control and internal ventilation. Ideal for engine rebuilds, upgrades, or restorations.
  • Compatible with air-cooled and water-cooled Porsche models.
