Diagram Ref No 24
Engine fasteners are subjected to continual heat cycles, vibration, and mechanical stress. Over time, original nuts can become corroded, suffer thread damage, or lose their ability to maintain the correct torque. This OE Match replacement restores the original specification and is ideal for engine rebuilds, repairs, and preventative maintenance.
What This Product Does:
- Secures the camshaft housing to the engine assembly.
- Maintains the correct clamping force on the camshaft housing.
- Helps ensure an effective seal between mating components.
- Resists loosening caused by engine vibration.
- Supports reliable engine assembly and operation.
- Restores the original factory specification.
- Replaces worn, damaged, or corroded original fasteners.
Symptoms Of Wear Or Failure:
- Corroded or rusted fasteners.
- Rounded or damaged socket head.
- Stripped or damaged threads.
- Nut failing to achieve the correct torque.
- Signs of previous overtightening or stretching.
- Loose camshaft housing fasteners.
- Oil seepage around the camshaft housing due to reduced clamping force.
- Missing hardware following engine repairs.
- Visible wear or mechanical damage.
- Fasteners showing signs of fatigue after repeated use.
Why Replacement Matters:
- The camshaft housing relies on correctly torqued fasteners to maintain alignment and provide an even clamping load across the sealing surfaces. Worn, damaged, or corroded nuts can compromise this clamping force, potentially leading to oil leaks, reduced reliability, or costly engine damage.
- Replacing ageing fasteners with OE Match components helps ensure the camshaft housing remains securely fastened and maintains the correct sealing pressure. Manufactured to OE-style specifications, this M8 socket head nut provides the correct fit, dependable performance, and factory-quality finish, making it an essential component during engine maintenance, repairs, or full restoration of your classic Porsche.

OEMatch Camshaft covers / Gaskets — Durability, Sealing, Performance
OEMatch camshaft covers and gaskets seal the upper engine area on Porsche models to prevent oil loss and protect valvegear from contamination. The range covers valve cover gaskets, complete cam cover assemblies and seal kits, chosen to support routine service, leak repair and engine preservation for Porsche vehicles.
Available Types
- Valve cover gaskets: rubber, composite and cork-style options
- Camshaft/cam cover assemblies in aluminium or composite finishes
- Seal kits including gaskets, O-rings, bolts and washers where applicable
Understanding OEMatch Camshaft covers / Gaskets
OEMatch provides a wide range of Porsche components, from gaskets to suspension hardware, engine parts, and interior trim.
OEM (Original Equipment Manufacturer) parts are made by the same company that produced your Porsche’s original camshaft covers and gaskets. OE (Original Equipment) refers to parts matching original specifications for camshaft covers and gaskets and may be supplied by alternative manufacturers. Aftermarket parts offer alternative options, sometimes with enhanced features or better value. OEMatch supplies non-OEM camshaft covers and gaskets engineered as direct-fit alternatives to OEM parts, made to original-spec dimensions and tolerances for Porsche models.
Benefits Include
- Restores reliable sealing to prevent oil leaks and residue
- Protects ignition coils and electrical components from oil contamination
- Helps maintain correct crankcase ventilation and oil control
Why Camshaft covers / Gaskets Wear and Fail
- Heat cycling and age harden gasket materials, causing cracks or shrinkage
- Oil contamination and chemical breakdown reduce sealing effectiveness
- Warped or corroded covers and damaged fasteners compromise the seal
The Importance of Replacing with OEMatch Camshaft covers / Gaskets
Timely replacement of camshaft covers and gaskets prevents oil loss that can lead to fouled spark plugs, misfires or damage to nearby components. Using correctly specified parts helps preserve engine cleanliness and lubrication on Porsche models and supports continued, predictable operation of the valvegear and associated systems.
Advantages
- Parts supplied with the correct form and sealing materials for typical Porsche applications
- Seal kits simplify repairs by including commonly replaced items
- Options in different materials to suit original or service preferences
