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

Diagram Ref No 15

By replacing both front dampers together, the set restores balanced suspension behaviour, consistent handling, and a smoother, more controlled ride. This is essential on vehicles where matched damping forces across the front axle are needed for proper steering response and stability.

This shock absorber smooths out bumps, potholes, and road imperfections to provide a more controlled and comfortable ride. It helps keep the front suspension stable during braking, cornering, and acceleration, supporting predictable steering and confident road-holding. By reducing unwanted oscillation, rebound, and vibration, it prevents instability and restores proper suspension performance when the original damper has become worn or ineffective.

Over time, shock absorbers lose their effectiveness through internal wear, fluid leaks, or weakened valving, which leads to a harsher ride and reduced suspension control. A worn damper allows excessive movement, causing instability, longer braking distances, and uneven tyre wear. Replacing it with a fresh OE-match unit restores proper damping, improves handling confidence, and helps maintain overall driving safety and comfort.

You should fit a new shock absorber if:
•  The ride has become bouncy, unsettled or harsh over uneven surfaces
•  Handling feels loose or unstable, especially at speed or under load
•  The vehicle exhibits uneven tyre wear, or suspension components show stress
•  Shock absorber shows leaks, damage or reduced damping performance
•  You are refreshing or upgrading the suspension for improved comfort or safety

Diagram ref no 1

Over time, PASM front shock absorbers lose their damping accuracy, which affects both comfort and handling. Worn dampers can cause inconsistent ride quality, reduced steering precision and poor stability over bumps or under braking. Replacing them restores full PASM functionality, ensuring the suspension reacts correctly in all modes and returns the 911’s signature balanced, confident road feel.

When to Replace:
• PASM fault messages appear
• Leaking hydraulic fluid from either damper
• Front suspension feels harsh, bouncy or unstable
• Noticeable decline in steering precision
• Completing a suspension refresh for optimal handling

This OE Match shock absorber set delivers factory-equivalent ride control and stability. Manufactured to meet OEM performance standards, these shocks provide precise damping response, dependable rebound control, and durable operation under both everyday driving and spirited use.

Replacing rear shocks as a pair ensures symmetrical damping on both sides, restoring correct chassis balance, rear-end stability, and consistent handling feel.

These rear dampers absorb road impacts and vibrations to provide a smoother, more controlled ride. They regulate both compression and rebound forces, helping the suspension respond predictably under all driving conditions. By maintaining proper alignment and reducing stress on surrounding components, they preserve the balanced, sporty ride quality expected from the 718 series.

Worn or weakened rear shocks can lead to:
• Reduced stability and grip
• Excessive bouncing over bumps
• Uneven or unpredictable handling
• Longer braking distances
• Accelerated tyre and suspension wear

Installing a pair restores proper damping performance, improves driving confidence, and preserves the balanced road feel.

Replace your rear shocks if you notice:
• Leaking fluid around the dampers
• Excessive bounce or instability at the rear
• Degraded ride comfort or harshness
• Uneven tyre wear or poor cornering response
• Suspension upgrades, repairs, or mileage-related wear (typically 50k–70k miles+)

Diagram ref no 1

As shock absorbers age, their damping performance deteriorates due to worn internal valves, leaks, seal wear or loss of fluid pressure. This degradation can lead to poor ride comfort, loss of control over suspension motion, increased body roll or instability - especially at higher speeds or under load. Replacing restores the original suspension performance and safety attributes.

When to replace:
• Ride becomes overly soft, bouncy or unstable over bumps or dips
• Rear feels vague, loose or unsettled under braking or cornering
• Rear tyres show uneven or accelerated wear
• Original shock is leaking fluid or the damping feels inconsistent
• Completed high-mileage or old suspension refresh - replacing springs, mounts, bushings or other related parts
• Preparing the vehicle for spirited driving, track use, or renewed performance expectations
