Diagram Ref No 13

Manufactured from high-grade steel and precision-machined internal components, the control element is engineered to operate reliably under high oil pressure and extreme engine temperatures. Designed for direct OE-style fitment, it integrates seamlessly with the engine's variable valve timing system, ensuring accurate camshaft adjustment throughout the engine's operating range.  

What This Product Does:
  • Controls oil flow to the variable camshaft timing system.
  • Regulates camshaft adjustment for optimum valve timing.
  • Helps improve engine performance and torque.
  • Supports better fuel efficiency and reduced emissions.
  • Provides fast and accurate camshaft timing response.
  • Works in conjunction with the engine management system.
  • Maintains smooth engine operation across all engine speeds.
  • Forms an essential part of the VarioCam (NVS) system.

Symptoms Of Wear Or Failure:
  • Check Engine Light illumination.
  • Camshaft timing fault codes.
  • Rough or unstable engine idle.
  • Reduced engine power or poor acceleration.
  • Increased fuel consumption.
  • Engine hesitation during acceleration.
  • Difficulty starting the engine.
  • Rattling noises associated with variable valve timing operation.
  • Engine entering reduced performance or limp mode.
  • Increased exhaust emissions.

Why Replacement Matters:

  • The camshaft control element operates continuously within the engine's lubrication system and is exposed to high oil pressure, elevated temperatures and constant actuation. Over time, internal wear, contamination from engine oil deposits or mechanical failure can reduce its ability to regulate oil flow accurately.
  • A faulty control element can prevent the variable valve timing system from operating correctly, leading to incorrect camshaft timing, reduced engine performance, poor fuel economy and increased emissions. Continued operation with a malfunctioning component may place additional strain on the camshaft adjusters and other timing system components.
  • Replacing a worn or defective camshaft control element restores accurate variable valve timing operation, allowing the engine management system to optimise performance, efficiency and drivability. The OE Match replacement provides factory-style fitment, precision engineering and long-lasting reliability, helping maintain the smooth operation, responsiveness and performance expected from your Porsche.

Fits:
Porsche 993 Carrera RS 3.7L 1995 - 1998

Diagram ref no 4

The sealing ring helps prevent oil, coolant or other fluids from leaking between closely fitted engine/transmission surfaces. It forms a compression seal around shafts or bores where fluid containment is critical. A properly functioning seal keeps fluids contained, minimizes the risk of contamination, and preserves lubrication where it’s needed most - such as around pistons, cylinders, or fluid passages.

Application: Engine or drivetrain sealing ring used in cylinder base or other fluid interface points where a precise rubber seal is required to maintain fluid containment and mechanical integrity.

Replace this sealing ring if you notice:
  Visible fluid leaks around engine or transmission joint areas
  Low oil or fluid levels without external explanation
  During engine or transmission removal and service
   When original seals show visible wear, cracking, or hardening

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.
