OE Match upper engine camshaft cover for Porsche 911 1968–89, 930 Turbo and 964 Turbo. It closes the upper camshaft housing and works with the sealing gasket to contain oil.


Fits

Porsche 930 Turbo
Porsche 964 Turbo

Diagram Ref No 24

What This Product Does

The cover forms a removable closure over the upper camshaft housing. Its mating surface provides a seat for the gasket, helping keep lubricant inside the assembly and dirt outside. A sound cover is important because replacing a gasket alone may not resolve leakage if the cover is distorted or damaged.

Functions

• Closes the upper camshaft housing.
• Provides the gasket mating surface.
• Helps contain oil and exclude contaminants.

Technical Details

• Brand: OE Match; installation position: Upper.
• Existing product reference: 90110511503.
• Internal exploded-diagram part reference: 90110511511.
• Internal diagrams specify two covers in the assembly; this does not identify the supplied pack quantity.

Symptoms of Fault

• Oil tracks around the cover joint or fixings.
• Leakage returning after gasket renewal.
• Visible cracks, distortion or deterioration of the mating surface.
• Oil odour or smoke when escaped lubricant reaches heated components.

Why Replacement Matters

A damaged cover can prevent the gasket from sealing correctly. Renewing a defective cover addresses that underlying problem during leak repairs or top-end work. Establish the leak source first, then inspect the gasket, mating surfaces and mounting hardware rather than assuming the cover is responsible.

FAQs

Will a new gasket be enough?
It may be sufficient when the cover remains undamaged and its mating surface is sound. Persistent leakage warrants checking both components.

Should the fixings simply be tightened?
Do not use extra tightening as a substitute for diagnosis. Excessive tightening may distort the cover or harm the threads; follow the applicable workshop procedure.

What should be checked before fitting?
Confirm the vehicle application and references, inspect the sealing surfaces, and establish which gasket and fixings the repair requires.

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.
