Cylinder head bolt long & head gaskets Porsche 996 3.4L

Engine Cylinder Head Gasket Kit
The cylinder head gasket is a critical component that seals the cylinder head to the engine block. It serves several key functions, It seals the combustion chamber, ensuring proper compression for efficient engine performance. It prevents coolant and engine oil from mixing by sealing the fluid passages between the cylinder head and engine block.

Signs of Cylinder Head Gasket Failure
A failing head gasket can lead to serious engine problems. Common symptoms include:

• Engine overheating
• Low cylinder compression
• External coolant or oil leaks
• White smoke from the exhaust
• Bubbles in the radiator or coolant reservoir
• Milky or white-colored engine oil

Differential mounting bush kit, 3 Parts (OE Ref: 2 x 95834933780 & 1 x  95834933790  ) 

The differential bushings secure the differential to the subframe. Over time, the rubber material naturally oxidizes, stretches, and deteriorates due to driving conditions and environmental exposure. As the bushings wear, the differential is allowed to shift, which can lead to clunking during acceleration, vibrations throughout the vehicle, and premature wear of the driveshaft and differential bearings.

Our Differential Bushing Kit provides all three rear differential bushings along with new mounting hardware, delivering a complete solution that restores your Cayenne’s performance, reliability, and safety.

Fits:
Porsche 958 Cayenne 3.6ltr V6 - 2014 to 2017

Porsche 958 Cayenne 4.8ltr V8 - 2014 to 2017
Porsche 958 Cayenne Diesel 3.0ltr - 2014 to 2017

This includes 2 x additional springs as one is required for each shock absorber.  This is for the shock absorber as an additional spring, also known as a bump stop, stopper or helper spring, designed for the front strut assemblies on Porsche 997 models equipped with the PASM electronic damper control (with sport shock I475 / I030).

This acts as a progressive load-bearing element, cushioning the suspension when the strut nears full compression. It helps prevent harsh bottoming-out, protecting both the strut and chassis from damage during aggressive driving or over bumps. These components maintain ride quality and handling performance, especially under heavy loading or spirited cornering, keeping the suspension linear and controlled. 

Common Issues & Considerations Wear or Deterioration: Over time, the rubber can compress, crack, or lose elasticity, diminishing its effectiveness. This can lead to harsher suspension impacts at full compression. Noise or Harsh Feedback: A worn or hardened bump stop can transmit noise or impacts through the cabin, particularly over rough roads or speed bumps. Sport vs. Standard Suspension: These parts are specific to Sport chassis models. Non-sport setups may not have the same bump stops or use different part numbers, so swapping or replacing must be done accordingly.

Valve stem seals.  SET OF 12 (12 required per engine.)

The valve stem seal, OEM part number 993 104 111 02 (sometimes superseding 993 104 111 01), is a component for the Porsche 993 series.

These seals are installed around the valve stems and serve to regulate, not entirely block, oil flow into the combustion chamber. They wipe excess oil off the valve stems and prevent undue oil burning or plug fouling. They are applicable across various 993 configurations—including the naturally aspirated Carrera and the Turbo variants—for 1994–1998 models.

Fits:

• Porsche 993 (911) C2 1994-97
• Porsche 993 (911) C4 1994-97
• Porsche 993 (911) RS 1994-97
• Porsche 993 (911) C2S 1994-97
• Porsche 993 (911) C4S 1994-97
• Porsche 993 (911) TURBO 1994-96
• Porsche 993 (911) GT2 1994-97
• Porsche 993 (911) TURBO S 1994-97  

Why You Should Replace Them

Over time, valve stem seals, typically rubber or elastomeric, can harden, crack, or shrink, especially under high heat and engine age—which compromises their sealing effectiveness.

Visible Symptoms:

• Blue exhaust smoke, particularly upon a cold start—leftover oil seeps past hardened seals and burns in the combustion chamber.
• Increased oil consumption without noticeable external leaks, as oil is being burned rather than escaping visibly.
• Smoke or puffing at idle or after deceleration, when high vacuum draws oil past failing seals.
• Compression or misfiring issues—oil-fouled spark plugs can disrupt ignition, and carbon buildup may mimic compression loss.

• Guaranteed fitment
• OE trailing arm bushing dimensions for correct alignment and smooth ride
• Restores proper suspension handling and braking stability
• High-quality heat-resistant elastomer and metal materials for maximum durability
• 24 Month Unlimited Mileage Warranty

Mount Hole Quantity: 1
Inside Diameter: 14.12 MM
Outside Diameter: 46 MM
Mount Hole Diameter: 34.4 MM
Material: Steal
Colour: Gold

Why replace them and typical age-related failures: Cracked or perished rubber → rear-end clunks, squeaks, and “rear-steer” feel on throttle/brake. Ovalised inner sleeve → unstable alignment; car wanders and tramlines. Oil/heat-swollen rubber → excess compliance and braking instability. Replacing restores correct alignment, handling and braking stability  

Common issues you’ll see Play at the trailing-arm pivot (visible with a pry bar); torn rubber. Uneven rear-tyre wear (inside edges from toe change under load). Noisy rear suspension over small bumps. Alignment won’t hold after a set-up (bushings deflect back).
