Product Information
Cylinder Head Cover Gasket.

The OE Match Cylinder Head Cover Gasket is a premium-quality replacement engine sealing component designed to provide a reliable, leak-free seal between the cylinder head cover (valve cover) and the cylinder head on compatible Porsche models. Manufactured to OE specifications for fit, sealing performance and durability, this precision-engineered gasket prevents engine oil leaks while protecting the valvetrain from dirt, moisture and other contaminants.

Fits:

  • Porsche 955 Cayenne 3.2L V6 2003-06


Diagram Ref No 21

Manufactured from premium heat-resistant, oil-resistant elastomer, the gasket is engineered to withstand continuous exposure to high engine temperatures, engine oil, pressure fluctuations and repeated thermal cycling without shrinking, hardening or cracking. Precision-moulded to match the original Porsche profile, it provides direct OE-style installation and dependable sealing performance, making it ideal for valve cover replacement, engine servicing or preventative maintenance.  

What This Product Does:

  • Creates a leak-free seal between the cylinder head cover and cylinder head.
  • Prevents engine oil from leaking from the valvetrain.
  • Protects internal engine components from dirt and moisture.
  • Maintains correct engine oil containment.
  • Helps keep the engine bay clean and free from oil contamination.
  • Supports reliable engine lubrication and performance.
  • Restores factory sealing performance.
  • Forms an essential part of the engine lubrication and valvetrain sealing system.

Symptoms Of Wear Or Failure:
  • Engine oil leaking around the cylinder head cover.
  • Oil residue on the cylinder head or engine block.
  • Burning oil smell caused by oil contacting hot exhaust components.
  • Oil spots beneath the vehicle.
  • Low engine oil level requiring frequent topping up.
  • Visible cracking, flattening or hardening of the gasket.
  • Oil contamination around ignition coils or spark plug wells where applicable.
  • Smoke from the engine bay caused by oil leaking onto hot components.
  • Engine bay contamination from oil seepage.
  • Premature deterioration of nearby rubber or electrical components due to oil exposure.

Why Replacement Matters:
  • The cylinder head cover gasket is continually exposed to high temperatures, hot engine oil and repeated heating and cooling cycles. Over time, the gasket material naturally hardens, shrinks or becomes brittle, reducing its ability to maintain an effective seal.
  • A leaking gasket can result in engine oil loss, contamination of ignition components and oil dripping onto hot exhaust parts, creating unpleasant odours and, in severe cases, visible smoke from the engine bay. Continued oil leakage may also reduce lubrication levels and accelerate wear of surrounding components.
  • Replacing a worn or damaged gasket with the OE Match Cylinder Head Cover Gasket restores the integrity of the engine sealing system and helps prevent costly oil leaks. Manufactured to OE standards using premium-quality oil- and heat-resistant materials, it provides factory-style fitment, exceptional sealing performance and long-lasting durability, ensuring the reliability, cleanliness and performance expected from your Porsche.
