x2 Engine Cover Valve Gaskets (94810593300/1)
x1 Engine Cylinder 1-4 Cover Gasket (94810593103/2)
x1 Engine Cylinder 5-8 Cover Gasket (94810593205/2)
x35 Round Head Bolt (99907334101)
Fits:
- Porsche 955 Cayenne S 4.5L V8 2003-06
- Porsche 955 Cayenne Turbo 4.5L 2003-06
Diagram Ref No 2, 3, 5
What This Product Does:
- Sealing the valve cover to the cylinder head to keep engine oil contained
- Preventing oil from entering the spark plug tubes
- Maintaining proper lubrication within the cylinder head
- Protecting ignition components from oil contamination
Symptoms Of Wear Or Failure:
- Oil leaking from the valve cover area
- Oil pooling inside spark plug wells
- Burning oil smell from the engine bay
- Engine misfires caused by oil-contaminated spark plugs
- Visible oil residue on the cylinder head or surrounding components
Why Replacement Matters:
- Prevents engine oil leaks and mess in the engine bay

Designed to the exact specifications of the original Porsche part, this premium replacement ensures a perfect seal, preventing oil leaks and maintaining optimal engine performance.
Why replacement matters.
Common Issues with Old / Failing Gaskets:
• With age, heat cycles, vibration, and exposure to oil and chemicals, the gasket material (often a composite rubber, elastomer, or multi-layer seal) can degrade, becoming brittle, cracked, or compressed beyond useful tolerance.
• A failed gasket allows oil leaks, which can lead to external oil dripping, contamination of other engine parts, or reduced oil levels.
• Oil leaks may also allow air ingress or blow-by, which can hamper engine performance or lead to further gasket failure.
• Leaks can cause unsightly stains, smoke (if oil contacts hot parts), and may even trigger engine warning lights or damage surrounding components.
When to replace:
• Anytime the valve cover is removed (e.g. for camshaft work, head servicing), the gasket should generally be replaced rather than reused.
• At the first signs of oil seepage or wetness around the valve cover edges.
• After extended usage (especially for vehicles over 100,000 miles or many years) as part of preventative maintenance.

OEMatch Cylinder Head / Camshaft Carrier — Fit, Function, Confidence
OEMatch offers cylinder head and camshaft carrier items for Porsche models that support repair, restoration and routine servicing. Many owners search for genuine or OEM cylinder head and camshaft carrier parts; OEMatch provides compatible replacements engineered to original-spec dimensions and tolerances to help maintain form and sealing where factory parts are unavailable.
Available Types
- Aluminium cylinder head and camshaft covers
- Composite camshaft carriers and covers
- Replacement valve covers with machined sealing faces
- Gaskets, seals and breather components
Understanding OEMatch Cylinder Head / Camshaft Carrier
OEM (Original Equipment Manufacturer) parts are made by the same company that produced your Porsche’s original cylinder head and camshaft carrier.
OE (Original Equipment) refers to parts matching original specifications for the cylinder head and camshaft carrier and may be supplied by alternative manufacturers. Aftermarket parts offer alternative options, sometimes with enhanced features or better value. OEMatch supplies non-OEM cylinder head and camshaft carrier parts engineered as direct-fit alternatives to OEM parts, made to original-spec dimensions and tolerances for Porsche models.
Cylinder head and camshaft carriers enclose the valvetrain and upper oilways, provide sealing surfaces for oil control and support ventilation paths; their condition affects lubrication, crankcase pressure and the protection of camshafts and related components. OEMatch maintains a wide catalogue of Porsche-related items, including service gaskets and sealing components, and records cross-references to aid selection for classic and modern engines.
Benefits Include
- Restores sealing to reduce oil leaks and maintain lubrication
- Protects camshafts, lifters and associated valvetrain components from contamination
- Supports correct crankcase ventilation and pressure balance
Why Cylinder Head / Camshaft Carrier Wear and Fail
- Heat cycles causing warping or stress-related cracking
- Degraded or hardened gaskets and seals leading to leaks
- Corroded or fatigued fasteners producing uneven clamp load
- Blocked or degraded breather passages increasing internal pressure
The Importance of Replacing with OEMatch Cylinder Head / Camshaft Carrier
Replacing worn covers and associated seals restores oil control, prevents leakage onto other engine parts and helps preserve long-term engine health. Correct sealing and intact ventilation reduce the risk of oil contamination and maintain consistent lubrication to critical valvetrain components, which is important for reliability and for maintaining the engine bay appearance expected on Porsche vehicles.
Advantages
- Material options such as aluminium and composite suited to different service needs
- Sealing faces and breather interfaces prepared to match original specifications where applicable
- Supplies and gaskets catalogued to assist repair and restoration of classic and modern Porsche engines
Support & Advice
Installation should be carried out by a qualified technician following model-specific procedures and torque settings. Use calibrated tools and new fasteners where specified. If you choose to carry out basic tasks yourself, protect surrounding finishes, confirm correct fixing hardware and recheck fasteners after initial mileage.
