The CV boot is a protective sealing component. It is exposed to suspension movement, road debris, water, salt, heat and age-related rubber deterioration. If the boot splits or loses its seal, grease can escape and contamination can enter the CV joint. Once the joint runs without lubrication or becomes contaminated, wear can develop quickly.

Replacing a damaged boot with a Genuine Porsche OE inner CV joint boot / repair set helps protect the drive shaft assembly and maintain proper drivetrain performance.

Common Symptoms of a Failed CV Boot
•  Grease visible around the drive shaft or suspension area
•  Split, cracked or torn rubber boot
•  Grease loss from the inner CV joint
•  Clicking, knocking or vibration if the CV joint has become worn
•  Dirt or water contamination inside the CV joint
•  Boot clamp failure or loose boot seating
•  MOT / roadworthiness failure due to damaged CV boot
•  Damage found during drivetrain or suspension inspection.

When to Replace This Part
•   If the inner CV boot is split, cracked or leaking grease
•   If the boot clamp has failed or the boot no longer seals correctly
•   During drive shaft repair or inspection
•   If the CV joint is being cleaned, repacked with grease or serviced
•   During suspension or drivetrain overhaul
•   After road debris, impact or service damage to the boot
•   Before CV joint wear develops from contamination
•   When restoring the drivetrain with Genuine Porsche parts.

Where It Fits on the Car
This repair set fits at the inner CV joint area of the drive shaft, where the shaft connects towards the drive unit / differential side. Correct installation requires proper cleaning, correct grease application, secure clamp fitment and inspection of the CV joint. If the joint has already been run without grease or has contamination damage, the CV joint or complete drive shaft should also be inspected.

Exhaust Gasket, Manifold To Downpipe, LHD. 
The Genuine Porsche Exhaust Gasket 477253115E is a replacement sealing component designed for the connection between the exhaust manifold and downpipe on compatible left-hand-drive (LHD) Porsche applications.

Fits:

• Porsche 924 2.0L 1976-79
• Porsche 924 2.0L 1980-85 

 
Diagram Ref No 11

This gasket creates a gas-tight seal at an important exhaust-system joint, preventing hot exhaust gases from escaping before they continue through the downpipe and the rest of the exhaust system.

Constant exposure to extreme temperatures, exhaust gases and repeated heating and cooling cycles can cause an old gasket to deteriorate, compress or burn through. Replacing a failed gasket helps restore a properly sealed exhaust connection, reduce unwanted exhaust noise and prevent hot gases leaking around the manifold-to-downpipe joint.

What This Product Does:
The exhaust gasket sits between the mating surfaces of the exhaust manifold and downpipe, creating a seal when the components are secured together.

Exhaust gases leave the engine at high temperature and pressure. These gases must remain contained within the exhaust system as they travel away from the engine.

The gasket helps:

• Create a gas-tight manifold-to-downpipe connection
• Prevent exhaust gases escaping through the joint
• Reduce unwanted exhaust noise
• Maintain proper exhaust-system integrity
• Protect surrounding components from escaping hot gases
• Prevent exhaust fumes leaking from the connection
• Maintain a secure seal despite repeated thermal expansion and contraction

Although relatively small, the gasket plays an important role in keeping the exhaust system correctly sealed.

Symptoms Of Wear Or Failure:
A deteriorated manifold-to-downpipe gasket can allow exhaust gases to escape through the connection.

Common symptoms may include:

• Ticking, tapping or blowing noise from the exhaust joint
• Increased exhaust noise
• Hissing or puffing sounds during acceleration
• Exhaust fumes or odour around the engine or underside of the vehicle
• Black soot deposits around the manifold-to-downpipe connection
• Visible signs of exhaust gas leakage
• Reduced exhaust-system sealing
• Noise that becomes more noticeable under load
• Heat damage or discolouration around the leaking joint
• Engine or emissions-related faults where applicable

A small leak may initially only be noticeable when the engine is cold or under acceleration.

Why Replacement Matters:
A leaking exhaust gasket should not be ignored.

Replacing a worn or damaged manifold-to-downpipe gasket helps:

• Restore a properly sealed exhaust connection
• Prevent hot exhaust gases escaping from the joint
• Reduce blowing, ticking and hissing noises
• Prevent soot accumulation around the connection
• Protect nearby components from concentrated exhaust heat
• Reduce the possibility of exhaust fumes entering areas where they should not
• Maintain correct exhaust-system operationRestore a cleaner and quieter exhaust system

A deteriorated gasket can progressively worsen as hot gases erode the sealing area.

Air Intake Manifold Connector Seal.
The Genuine Porsche Air Intake Manifold Connector Seal 99311072340 is a replacement sealing component designed to provide an airtight connection within the intake manifold system on compatible Porsche applications.

Fits:

• Porsche 993 (911) C2 1994-97
• Porsche 993 (911) C4 1994-97

  
Diagram Ref No 24

The engine's intake system relies on properly sealed connections to ensure that the correct amount of air reaches the engine. This seal is fitted at the relevant intake manifold connector, helping prevent unwanted air from entering through the joint.

Over time, exposure to engine heat, vibration and repeated temperature cycles can cause the original seal to harden, shrink, crack or lose elasticity. A deteriorated intake seal can create an air or vacuum leak, potentially affecting idle quality, engine performance and air/fuel mixture control.

What This Product Does:
The intake manifold connector seal creates an airtight joint between the relevant components of the engine intake system.

During operation, the engine draws air through the intake system and into the cylinders. Connections downstream in the intake tract must remain properly sealed so that unwanted air cannot enter through gaps between components.

A correctly functioning connector seal helps:

• Maintain an airtight intake connection
• Prevent vacuum and intake air leaks
• Reduce unwanted or unmetered air entering the engine
• Support stable engine idle
• Maintain consistent engine performance
• Support correct air/fuel mixture control
• Maintain intake-system integrity

Even a relatively small leak can affect engine operation, particularly at idle when intake vacuum can be significant.

Symptoms Of Wear Or Failure:
A deteriorated intake seal can allow air to enter through the manifold connection rather than through the intended intake path.

Possible symptoms include:

• Rough or unstable idle
• Higher than normal idle speed
• Fluctuating or hunting idle
• Engine hesitation
• Reduced throttle response
• Poor or inconsistent engine performance
• Lean-running symptoms
• Difficult starting
• Engine misfires
• Increased fuel consumption
• Engine warning light on vehicles with applicable diagnostics
• Air/fuel mixture or lean-condition fault codes where applicable
• Hissing or whistling noise from the intake area

Symptoms may vary according to the size and location of the leak.

Why Replacement Matters:
An intake air leak can affect the engine's ability to maintain the intended air/fuel mixture and stable operating conditions.

Replacing a deteriorated intake manifold connector seal helps:

• Restore an airtight intake connection
• Prevent unwanted air or vacuum leakage
• Improve idle stability
• Support consistent throttle response
• Maintain correct intake-system operation
• Support accurate air/fuel mixture control
• Reduce lean-running problems caused by intake leaks
• Restore reliable engine performance

Ignoring an intake leak can result in persistent drivability problems and make accurate engine tuning or diagnosis more difficult.

• Porsche 928GTS 5.4L 1992-95  

Diagram Ref No 1 And 2

The cylinder head gasket must withstand high combustion pressures, elevated operating temperatures and constant heating and cooling cycles. Its primary role is to maintain compression and combustion sealing while keeping oil, coolant and combustion areas correctly separated where applicable to the engine design.

A damaged or incorrectly sealing head gasket can cause compression loss, overheating, fluid leakage and poor engine performance. If left unresolved, cylinder head gasket failure can potentially result in extensive internal engine damage.

What This Product Does:
The cylinder head gasket creates a high-pressure seal between the cylinder head and engine assembly.

During combustion, considerable pressure is generated inside the cylinders. The gasket must contain this pressure while maintaining separation between the combustion chambers and the engine's oil and coolant passages where applicable.

A correctly functioning cylinder head gasket helps:

• Maintain cylinder compression
• Contain combustion pressure
• Prevent combustion gases escaping through the cylinder head joint
• Keep engine oil and coolant within their intended passages
• Prevent unwanted mixing of engine fluids
• Support consistent combustion and engine performance
• Help maintain correct operating temperatures
• Maintain the integrity of the cylinder head assembly

The gasket must continue performing these functions despite repeated expansion and contraction of the surrounding engine components.

Symptoms Of Wear Or Failure:
Cylinder head gasket failure can produce different symptoms depending on where the sealing interface has been compromised.

Possible warning signs include:

• Engine overheating
• Loss of cylinder compression
• Reduced engine power
• Rough or uneven running
• Engine misfires
• Difficult starting
• Unexplained coolant loss
• Oil leakage around the cylinder head joint
• Abnormal exhaust smoke or vapour
• Increased cooling-system pressure
• Combustion gases entering the cooling system
• Oil contamination of coolant
• Coolant contamination of engine oil
• Increased oil consumption

A failing head gasket does not necessarily produce an obvious external leak. Internal leakage between combustion chambers or fluid passages may require diagnostic testing to identify.

Why Replacement Matters:
A failed cylinder head gasket can affect several critical engine functions simultaneously.

Loss of combustion sealing can reduce compression and performance, while leakage between oil or coolant passages can cause fluid contamination and temperature-control problems.

Replacing a failed gasket helps:

• Restore cylinder compression
• Restore combustion sealing
• Prevent combustion gas leakage
• Prevent unwanted oil or coolant leakage where applicable
• Maintain separation between engine fluid circuits
• Support stable engine operating temperatures
• Restore consistent engine performance
• Reduce the risk of progressive internal engine damage

Continuing to operate an engine with a failed head gasket can potentially lead to overheating, lubrication problems, cylinder head damage and substantially more extensive repairs.

Cylinder Head Gasket.
The Genuine Porsche Cylinder Head Gasket 92810437112 / 92810437212 is a replacement engine sealing component designed for compatible Porsche applications. Installed at the interface between the cylinder head and engine assembly, the gasket provides a critical seal capable of withstanding the high temperatures and combustion pressures generated during normal engine operation.

Fits:

Diagram Ref No 2 And 3

A cylinder head gasket is one of the engine's most important sealing components. It helps maintain cylinder compression and combustion sealing while keeping engine fluids within their intended passages where applicable.

Over time, repeated heat cycles, overheating, component distortion or incorrect installation can compromise the gasket. A failed cylinder head gasket can lead to compression loss, fluid leakage, overheating and potentially significant engine damage if the problem is ignored.

What This Product Does:
The cylinder head gasket creates a high-integrity seal between the cylinder head and its mating engine surface.

During combustion, extremely high pressure is generated inside each cylinder. The gasket must contain this pressure while also maintaining separation between adjacent engine passages where required.

A correctly functioning cylinder head gasket helps:

• Maintain cylinder compression
• Seal combustion pressure
• Prevent combustion gases escaping from the cylinder
• Keep oil and coolant within their intended passages where applicable
• Prevent unwanted mixing of engine fluids
• Maintain consistent engine performance
• Support correct engine operating temperature
• Maintain overall cylinder head sealing integrity

The gasket must continue performing these functions while repeatedly expanding and contracting as the engine heats up and cools down.

Symptoms Of Wear Or Failure:
Cylinder head gasket failure can produce a wide range of symptoms depending on where and how the sealing surface has failed.

Possible symptoms include:

• Engine overheating
• Loss of compression
• Reduced engine performance
• Rough running or misfiring
• Difficult starting
• Uneven cylinder performance
• Unexplained coolant loss where applicable
• Engine oil leakage around the cylinder head joint
• Abnormal exhaust smoke
• Increased pressure within the cooling system
• Oil or coolant contamination
• Combustion gases entering the cooling system
• Bubbles or abnormal pressure in the coolant expansion system
• Increased oil consumption

A failing gasket does not always produce an obvious external leak. Internal leakage can occur between combustion chambers or fluid passages.

Why Replacement Matters:

A failed cylinder head gasket should not be treated as a minor engine leak.

Once sealing integrity has been compromised, combustion pressure or engine fluids may begin travelling into areas where they should not be present.

Replacing a failed gasket helps:

• Restore cylinder compression
• Restore combustion sealing
• Prevent combustion gas leakage
• Prevent unwanted oil or coolant leakage where applicable
• Maintain separation between engine fluid circuits
• Support stable engine temperatures
• Restore consistent engine performance
• Reduce the risk of progressive engine damage

Continuing to operate an engine with a failed cylinder head gasket can potentially cause overheating, cylinder head damage, contaminated lubrication and more extensive internal engine problems.

Cylinder head sealing is essential for correct engine performance. The gasket helps maintain the required seal between mating engine components, preventing combustion pressure and engine fluids from escaping into areas where they do not belong.

Because this gasket operates in an extremely demanding environment, deterioration, overheating, incorrect installation or engine component distortion can eventually compromise its sealing ability. A failed cylinder head gasket should be addressed promptly to prevent further engine damage.

What This Product Does:
The cylinder head gasket creates a high-integrity seal at the cylinder head interface.

Depending on the engine design, this sealing interface must withstand combustion pressure, high operating temperatures and the circulation of engine fluids through adjacent passages.

A correctly functioning cylinder head gasket helps:

• Maintain cylinder and combustion sealing
• Prevent combustion gases escaping from the sealing interface
• Keep engine fluids within their intended passages
• Maintain correct engine compression
• Support consistent engine performance
• Protect adjoining engine components from leakage
• Maintain the integrity of the cylinder head assembly

Unlike a simple external seal, a cylinder head gasket must continue sealing while exposed to substantial pressure and repeated thermal expansion and contraction.

Symptoms Of Wear Or Failure:
Cylinder head gasket failure can present in different ways depending on where the gasket has lost its seal.

Possible symptoms include:

• Loss of engine compression
• Reduced engine performance
• Rough running or misfiring
• Difficult starting
• Abnormal combustion leakage
• Oil leakage around the cylinder head sealing area
• Unusual engine temperatures or overheating
• Increased oil consumption
• Abnormal exhaust smoke
• Unexplained fluid loss where applicable
• Contamination between fluid passages where applicable
• Unusual pressure within associated engine systems

External signs may include visible staining, seepage or deposits around the cylinder head joint.

Some cylinder head gasket problems may not produce an obvious external leak, making correct diagnosis important before dismantling the engine.

Why Replacement Matters:
A compromised cylinder head gasket can affect compression, engine performance and sealing integrity.

Continuing to operate an engine with a failed gasket may allow a relatively localised sealing problem to develop into more extensive engine damage.

Replacing a failed cylinder head gasket helps:

• Restore the cylinder head sealing interface
• Maintain correct compression
• Prevent combustion gas leakage
• Reduce engine fluid leakage where applicable
• Restore consistent engine operation
• Protect surrounding engine components
• Reduce the risk of further engine damage

Cylinder head gasket problems should therefore be investigated promptly rather than treated as a minor leak.

Fuel System O-Ring.
The Genuine Porsche Fuel System O-Ring 61610842300 is a replacement sealing component designed to provide a secure, leak-resistant seal within the fuel system on compatible Porsche applications.

Fits:

• Porsche 911 1965-1968 2.0L / 912 SWB (F)
• Porsche 356A 1955-59
• Porsche 356B 1959-63
• Porsche 356C 1963-65  

Diagram Ref No 8

Although small, an O-ring performs an essential job. It seals the connection between mating fuel-system components, helping prevent liquid fuel and fuel vapour from escaping while maintaining the integrity of the fuel circuit.

Over time, continuous exposure to fuel, heat and repeated temperature cycles can cause the original O-ring to harden, flatten, crack or lose elasticity. It can also be damaged when components are removed or refitted. Replacing a deteriorated seal helps maintain a safe and reliable fuel-system connection.

What This Product Does:
The O-ring sits between mating components within the fuel system and is compressed during assembly to create a fuel-tight seal.

Its primary purpose is to prevent fuel or fuel vapour from escaping through the joint while allowing the fuel system to operate as intended.

A correctly functioning O-ring helps:

• Prevent liquid fuel leakage
• Reduce the escape of fuel vapour
• Maintain a secure fuel-system connection
• Maintain fuel-system integrity
• Protect surrounding components from fuel contamination
• Support safe and reliable vehicle operation

Because parts of the fuel system may operate under pressure, the condition and correct installation of sealing components are particularly important.

Symptoms Of Wear Or Failure:
A deteriorating O-ring may initially produce only a very small leak, but this should not be ignored.

Possible symptoms include:

• Noticeable fuel smell
• Fuel odour around the relevant connection
• Visible fuel seepage
• Dampness around the sealed joint
• Fuel staining or residue
• Persistent fuel vapour smell
• Leakage after fuel-system servicing
• Loss of sealing integrity around the connection

When removed and inspected, a failed O-ring may appear:

• Hard or brittle
• Cracked or split
• Flattened from prolonged compression
• Stretched
• Swollen
• Distorted
• Cut or nicked
• Permanently deformed

Any O-ring showing signs of deterioration or physical damage should be replaced.

Why Replacement Matters:
Fuel-system sealing components are safety-critical parts.

A failed O-ring can allow fuel or vapour to escape from the system. Besides causing fuel loss and unpleasant odours, leaking fuel can create a serious fire risk, particularly when it reaches hot surfaces or an ignition source.

Replacing a worn or damaged O-ring helps:

• Restore a secure fuel-tight connection
• Prevent fuel leakage
• Reduce fuel vapour escape
• Maintain fuel-system integrity
• Protect surrounding components from contamination
• Support safe and reliable vehicle operation

Any suspected fuel leak should be investigated and repaired promptly.

Oil Cooler Seal.
The Genuine Porsche Oil Cooler Seal 61610112300 is a replacement sealing component designed to provide an oil-tight connection at the engine oil cooler on compatible Porsche applications.

Fits:

• Porsche 356 1950-55
• Porsche 356A 1955-59  

Diagram Ref No 2

The oil cooler forms an important part of the engine lubrication and temperature-control system. Its job is to transfer excess heat away from the engine oil, while the associated seals ensure that oil remains securely contained as it passes through the cooler assembly.

Although the seal itself is a relatively small component, deterioration can result in engine oil leakage around the oil cooler. Replacing an ageing, hardened or damaged seal helps restore sealing integrity and protect the engine from progressive oil loss.

What This Product Does:
The oil cooler seal creates a secure barrier between the oil cooler and its mating engine component, preventing engine oil from escaping at the connection.

During engine operation, oil circulates through the lubrication system and oil cooler. The seal must remain effective while exposed to engine oil, elevated temperatures and repeated pressure and temperature changes.

A correctly functioning oil cooler seal helps:

• Prevent engine oil leakage
• Maintain an oil-tight oil cooler connection
• Keep oil contained within the lubrication system
• Support reliable oil circulation
• Prevent contamination of surrounding engine components
• Maintain the integrity of the engine oil cooling system

Without an effective seal, oil can escape from the cooler connection rather than remaining contained within the lubrication circuit.

Symptoms Of Wear Or Failure:
Oil cooler seals can deteriorate gradually with age, making minor seepage one of the first signs of a problem.

Common symptoms can include:

• Engine oil leaking around the oil cooler
• Oil seepage at the cooler connection
• Wet or oily residue around the oil cooler
• Oil staining on surrounding engine components
• Oil spots underneath the vehicle
• Gradual reduction in engine oil level
• Increased need to top up engine oil
• Burning-oil smell if leaked oil reaches hot surfaces
• Smoke if oil contacts sufficiently hot exhaust or engine components

During inspection, an old seal may also show:

• Hardening
• Brittleness
• Cracking or splitting
• Flattening from prolonged compression
• Cuts or surface damage
• Loss of elasticity
• Permanent deformation

These conditions indicate that the seal may no longer provide a reliable oil-tight connection.

Why Replacement Matters:
The engine depends on an adequate supply of oil for lubrication, cooling and protection of internal components.

A leaking oil cooler seal may begin with relatively minor seepage, but continued deterioration can allow increasing amounts of oil to escape.

Replacing a failed seal helps:

• Prevent engine oil loss
• Restore a secure oil cooler connection
• Maintain lubrication-system integrity
• Keep the engine and surrounding components cleaner
• Reduce the risk of oil reaching hot components
• Prevent minor seepage developing into a larger leak
• Support reliable engine operation

Ignoring an oil leak can eventually result in the engine operating with an insufficient oil level. If oil loss becomes significant, lubrication of critical internal components can be compromised.

Oil Filter Housing O-Ring.
The Genuine Porsche Oil Filter Housing O-Ring 99970110050 is a replacement sealing ring designed to provide a secure, oil-tight seal at the oil filter housing on compatible Porsche applications.
Fits:

• Porsche 911 1965-1968 2.0L
• Porsche 911 1970-1973 2.2L / 2.4L / 2.7L RS LWB (F)
• Porsche 914 (1970-1976)  

Diagram Ref No 9

Although it is a small component, the O-ring plays an important role in the engine lubrication system. It prevents engine oil from escaping at the sealed connection and helps the lubrication system maintain its integrity during operation.

Repeated exposure to hot engine oil, pressure and temperature cycles can eventually cause the original O-ring to harden, flatten, crack or lose elasticity. Once this happens, oil can begin to seep or leak from the oil filter housing area.
What This Product Does:
The O-ring creates a seal between mating surfaces within the oil filter housing assembly.

When installed correctly, the O-ring is compressed to close the small clearance between components through which pressurised engine oil could otherwise escape.

A correctly functioning oil filter housing O-ring helps:

• Prevent engine oil leakage
• Maintain a secure oil filter housing seal
• Keep oil contained within the lubrication system
• Prevent oil contamination of surrounding engine components
• Support correct lubrication-system operation
• Maintain a clean and dry oil filter housing area

The correct dimensions and sealing specification are important because an incorrectly sized O-ring may leak even if it appears similar to the original component.
Symptoms Of Wear Or Failure:
O-rings gradually deteriorate through age, heat and repeated compression.

Common symptoms of a worn oil filter housing O-ring include:

• Engine oil leaking around the oil filter housing
• Oil seepage around the sealed joint
• Damp or oily residue on surrounding components
• Oil collecting beneath the engine
• Gradual reduction in engine oil level
• Burning-oil smell if leaked oil reaches hot components
• O-ring becoming hard or brittle
• Cracking or splitting
• Flattened sealing surface
• Cuts, nicks or deformation
• Leakage appearing after oil filter servicing

A minor seep can gradually develop into a more significant leak as the seal continues to deteriorate.
Why Replacement Matters:
Engine oil is essential for lubricating and protecting internal engine components.

A leaking oil filter housing seal can result in gradual oil loss and contamination of surrounding components. If a significant leak is ignored and the engine oil level becomes too low, lubrication can be compromised.

Replacing a worn O-ring helps restore:

• A secure oil-tight connection
• Proper oil filter housing sealing
• Engine oil retention
• A cleaner engine compartment
• Correct lubrication-system integrity
• Protection against progressive oil loss

Addressing an oil leak promptly can also make it easier to identify any additional leaks elsewhere on the engine.
