OE Match

Cylinders With Piston Set, Flat Top 90x66mm.

The OE Match Cylinders With Piston Set is a complete replacement piston-and-cylinder kit designed for Porsche 914 models using the 1700cc Type 4 engine and 66mm-stroke crankshaft.

Featuring 90mm cast-iron cylinders and flat-top hypereutectic aluminium-alloy pistons, the kit provides the major reciprocating and cylinder components required to restore worn or damaged 1.7-litre Type 4 engine assemblies.

The flat-top piston design is intended for lower-compression engine builds, while the 42mm compression height provides the correct piston geometry for compatible 66mm-stroke applications.

Supplied as a matched set of four cylinders and pistons, together with piston pins and piston rings, the kit is well suited to complete engine rebuilds, restoration projects and repairs where the original cylinders or pistons have suffered excessive wear.

Fits:

• Porsche 914, Type 4

Engine size: 1700cc
Stroke: For 66mm stroke crankshafts
Pistons: Hypereutectic aluminium alloy
Compression Height: 42mm

Set includes: 4 pistons, 4 cylinders, 4 pins and a set of rings.

What This Product Does:

The piston and cylinder assembly forms the heart of the engine's combustion process.

During operation, each piston moves up and down inside its cylinder as combustion pressure acts on the piston crown. This converts the energy released by burning the air/fuel mixture into mechanical movement through the connecting rods and crankshaft.

The set is designed to:

• Restore worn 90mm cylinders.
• Replace damaged or excessively worn pistons.
• Restore correct piston-to-cylinder clearances when properly installed.
• Help restore engine compression.
• Provide effective sealing through new piston rings.
• Reduce excessive combustion-gas blow-by.
• Help reduce oil consumption caused by worn cylinders or rings.
• Restore more consistent combustion between cylinders.
• Support reliable power production.
• Provide the correct geometry for a 66mm-stroke 1700cc Type 4 engine.
• Provide a matched four-cylinder replacement solution during an engine rebuild.

Symptoms Of Wear Or Failure:
Possible signs of piston, ring or cylinder wear include:

• Low engine compression.
• Uneven compression between cylinders.
• Poor leak-down test results.
• Reduced engine power.
• Sluggish acceleration.
• Difficult starting.
• Excessive oil consumption.
• Blue smoke from the exhaust.
• Combustion gases entering the crankcase.
• Excessive crankcase blow-by.
• Oil contamination around the breather system.
• Increased engine fumes.
• Piston slap or knocking noises.
• Reduced combustion efficiency.
• Fouled spark plugs.
• Excessive carbon deposits.
• Poor idle quality.
• Loss of performance as the engine warms.
• Cylinder scoring identified during dismantling.
• Excessive piston-to-cylinder clearance.
• Broken or damaged piston rings.
• Cracked piston ring lands.
• Damaged piston skirts or crowns.

These symptoms can also result from valve, cylinder-head or other internal engine problems, so compression and leak-down testing should form part of diagnosis before dismantling.

Why Replacement Matters:
The piston, rings and cylinder must work together to create an effective seal inside each combustion chamber.

As these components wear, combustion pressure can escape past the piston rings and into the crankcase rather than acting efficiently on the piston.

Replacing worn components helps restore:

• Cylinder sealing.
• Compression.
• Engine power.
• Throttle response.
• Oil control.
• More consistent combustion.
• Reduced blow-by.
• Reduced oil burning.
• Reliable long-term engine operation.

For an engine rebuild, replacing pistons and cylinders as a complete matched set also helps avoid mixing heavily worn components with new parts.

Set OfC Gaskets For 40 PBIC And 40 PICB.

The OE Match Carburettor Gasket Set is a replacement sealing kit for Solex 40 PBIC and 40 PICB carburettors fitted to early Porsche 356 applications.
x2 Required Per Car.

Fits:

• Porsche 356 Pre-A / 356 A Super engines

Carburettor gaskets create seals between the various sections and mating surfaces of the carburettor assembly. These seals are essential for preventing unwanted air leaks, fuel seepage and loss of vacuum that can interfere with correct fuel metering and engine operation.

Over time, original gasket material can harden, shrink, crack or become damaged during disassembly. Reusing old gaskets after a carburettor has been opened can also lead to unreliable sealing. Installing fresh gaskets during servicing or rebuilding helps restore correct sealing and dependable carburettor operation.

What This Product Does:

• Seals mating surfaces within the Solex carburettor assembly.
• Helps prevent fuel leaks from carburettor joints.
• Helps prevent unwanted air or vacuum leaks.
• Supports accurate air/fuel metering.
• Helps maintain stable idle and predictable throttle response.
• Provides fresh sealing components during carburettor rebuilding.
• Replaces hardened, compressed or damaged original gaskets.
• Helps restore reliable operation after carburettor disassembly.
• Supports correct sealing of the 40 PBIC and 40 PICB carburettors.

A carburettor relies on controlled airflow and precisely metered fuel. Air entering through an unintended gasket leak can disturb the mixture, while fuel leakage creates both running problems and a potential safety concern.

Symptoms Of Wear Or Failure:
Possible signs of deteriorated carburettor gaskets include:

• Fuel seepage around carburettor joints.
• Strong petrol smell in the engine compartment.
• Dampness or staining around gasket surfaces.
• Rough or unstable idle.
• Engine idle speed that is difficult to adjust.
• Lean running caused by unwanted air entering the carburettor.
• Hesitation during acceleration.
• Poor throttle response.
• Uneven engine running.
• Difficult starting.
• Carburettor mixture settings that will not remain consistent.
• Increased fuel consumption.
• Visible cracking, shrinking or hardening of gasket material.
• Gaskets tearing when the carburettor is dismantled.
• Vacuum leaks detected around carburettor mating surfaces.

These symptoms can also be caused by worn throttle shafts, blocked jets, incorrect float levels or other carburettor faults, so the complete carburettor should be inspected during diagnosis.

Why Replacement Matters:
Carburettor gaskets are designed to seal accurately between components. Once the gasket material has been compressed and exposed to fuel, heat and repeated temperature cycles, it may no longer reseal effectively after removal.

A damaged gasket can allow either fuel or air to pass where it should not.

Replacing worn gaskets helps restore:

• Correct carburettor sealing.
• Stable idle.
• Accurate fuel metering.
• Consistent throttle response.
• Reduced risk of fuel leakage.
• Reliable starting.
• Better carburettor adjustment.
• Cleaner and safer engine-bay operation.

Carburetor Throttle Shaft 40 PICB.

The OE Match Carburettor Throttle Shaft is a precision replacement component for compatible Solex 40 PICB carburettors fitted to early Porsche 356 applications.
This is a new shaft CNC machined and black zinc plated.

Fits:

• Porsche 356 Pre-A / 356 A with the 1500 S engine

Diagram Ref No 2

The throttle shaft passes through the carburettor body and carries the throttle butterfly or throttle plate. Movement from the accelerator linkage rotates the shaft, opening or closing the throttle plate to regulate the quantity of air and fuel mixture entering the engine.

Because the shaft operates every time the accelerator is pressed or released, both the shaft and the corresponding carburettor-body bores can wear over time. Excessive clearance can allow unwanted air to enter around the shaft, which may disturb the carburettor mixture and make accurate idle adjustment difficult.

This replacement shaft is CNC machined and black zinc plated, providing a precision replacement when rebuilding or restoring the original carburettor.

What This Product Does:

• Provides the pivot shaft for the carburettor throttle plate.
• Transfers accelerator-linkage movement to the throttle butterfly.
• Opens the throttle plate as the accelerator is pressed.
• Allows the throttle plate to close correctly when the accelerator is released.
• Helps maintain accurate throttle positioning.
• Supports stable idle and predictable throttle response.
• Helps maintain correct carburettor airflow control.
• Reduces excessive linkage movement when replacing a worn shaft.
• Helps restore correct carburettor operation during rebuilding.
• Provides a precision replacement for a worn, corroded or damaged original shaft.

The Porsche parts catalogue shows the throttle shaft working directly with the throttle valve, retaining screws, lever, seals and associated carburettor hardware.

Symptoms Of Wear Or Failure:
Possible symptoms include:

• Excessive sideways movement or play in the throttle shaft.
• Loose or imprecise throttle linkage.
• Unstable or inconsistent idle.
• Difficulty setting the idle speed correctly.
• Engine speed changing when the throttle shaft is moved sideways.
• Hesitation during initial throttle application.
• Poor or inconsistent throttle response.
• Engine running lean at idle.
• Carburettor mixture adjustment becoming difficult.
• Uneven running at low engine speeds.
• Throttle plate failing to return consistently to the same closed position.
• Sticking or stiff throttle movement.
• Visible shaft wear or scoring.
• Corrosion on the shaft.
• Excessive clearance between the shaft and carburettor body.

Current specialist cataloguing notes that throttle-shaft wear or excessive bore clearance can lead to poor throttle response, uneven idle and incorrect fuel metering.

Why Replacement Matters:
The carburettor depends on precise control of airflow through the throttle plate.

When the throttle shaft or its supporting bore becomes worn, the shaft can move laterally rather than simply rotating around its intended axis. This can affect both throttle-plate positioning and the sealing of the shaft within the carburettor body.

Excessive shaft clearance may allow unmetered air to enter the carburettor. Because this air bypasses the normal calibrated airflow path, the engine's air/fuel mixture can become difficult to control, particularly at idle and small throttle openings.

Replacing a worn throttle shaft helps restore:

• Accurate throttle movement.
• Reduced throttle linkage play.
• More consistent throttle-plate positioning.
• Improved idle stability.
• More predictable throttle response.
• Correct carburettor adjustment.
• Reliable operation of the accelerator linkage.

• Protects the reservoir opening during driving and storage.
• Works with the appropriate reservoir cap seal.
• Replaces a cracked, damaged, distorted or poorly fitting original cap.
• Helps restore the original brake reservoir arrangement during servicing or restoration.

Brake fluid is hygroscopic, meaning it naturally absorbs moisture from the atmosphere. A properly fitted reservoir cap and seal help limit unnecessary contamination of the fluid.

Symptoms Of Wear Or Failure:
Possible signs that the cap requires replacement include:

• Cap becoming loose or failing to tighten securely.
• Cracks in the cap.
• Damaged or worn threads.
• Physical distortion.
• Brake fluid residue around the reservoir opening.

• Original cap missing during restoration or servicing.

Brake fluid around the reservoir does not always mean the cap itself is responsible. An overfilled reservoir, damaged seal, cracked reservoir or other hydraulic issue should also be checked.

Why Replacement Matters:
The brake fluid reservoir supplies hydraulic fluid to the braking system. Keeping that fluid clean and properly contained is important for safe and consistent brake operation.

A damaged or poorly fitting cap can allow increased exposure to:

• Dirt.
• Dust.
• Moisture.
• Workshop contamination.
• Road debris.

Replacing the cap helps maintain a properly protected reservoir and reduces the likelihood of contaminants entering the hydraulic system.

Diagram Ref No 25

The spring plate forms an important connection between the rear suspension and the torsion bar. As the rear wheel moves through its suspension travel, the spring plate transfers that movement into the torsion bar, which twists to provide the springing force required to support the rear of the vehicle.

The integrated rubber bushing supports the spring plate within its mounting point while allowing controlled rotational movement. It also helps isolate vibration and prevents excessive metal-to-metal movement between the spring plate and surrounding suspension structure.

Over time, original spring plates can suffer from corrosion, while the rubber bushings can harden, crack, compress or deform. Replacing the complete assembly helps restore correct suspension movement, rear ride height and predictable handling.

What This Product Does:

• Connects the rear suspension to the torsion bar.
• Transfers suspension movement and load into the torsion bar.
• Allows the torsion bar to provide the rear springing force.
• Helps maintain correct rear ride height.
• Supports stable rear suspension geometry.
• Helps control wheel movement during acceleration, braking and cornering.
• Uses a rubber bushing to provide controlled articulation.
• Helps isolate suspension vibration and noise from the chassis.
• Prevents excessive movement at the spring plate mounting point.

Gearshift Lever Boot 

OE Match gearshift lever boot for Porsche 356 and 356A models from 1950 to 1961. Designed as an original-style replacement, this flexible protective boot fits around the base of the gear lever, helping prevent dirt, dust and moisture from entering the gearshift mechanism.

Fits:

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

Diagram ref no 11

Manufactured to replicate the fit and function of the original component, the boot provides a neat, period-correct finish to the gear lever assembly. It is ideal for replacing an aged, cracked, split or missing original boot during routine maintenance or classic Porsche restoration.

What Does the Gearshift Lever Boot Do?

The gearshift lever boot forms a protective barrier around the base of the manual gear lever, helping keep dust, dirt and moisture away from the gearshift mechanism.

Its flexible construction allows the gear lever to move freely during gear selection while helping reduce the transfer of unwanted noise and draughts into the passenger compartment.

The boot also provides a tidy, original-style finish around the gear lever, maintaining the authentic appearance of the classic Porsche interior.

Why Does It Fail?

Over time, the original gearshift lever boot can deteriorate due to age, repeated movement and environmental exposure.

Common causes of failure include:

• Rubber hardening and loss of flexibility
• Cracking or splitting through age
• Repeated movement of the gear lever
• Heat and temperature changes
• Exposure to dirt, moisture and cleaning chemicals
• Damage during previous gearshift repairs
• General wear and deterioration

Once the boot becomes brittle or damaged, it may no longer provide an effective protective barrier around the gearshift assembly.

When Should It Be Replaced?

Replacement is recommended if the existing gearshift boot shows any of the following:

• Visible cracks or splits
• Hardened or brittle material
• Loose or poor fitting around the gear lever
• Missing or damaged sections
• Excessive dirt entering the gearshift mechanism
• An untidy or deteriorated appearance

The boot should also be inspected whenever the gearshift lever or associated linkage components are removed for servicing.

Checks During Replacement

When replacing the gearshift lever boot, also inspect:

• Gearshift lever and mounting
• Gearshift lever bushes
• Gearshift stop plate
• Gearshift linkage and couplings
• Associated retaining components
• Surrounding transmission tunnel area

Any worn or damaged gearshift components should be repaired or replaced to maintain correct gear selection and smooth operation.

Porsche 356 / 356A Gearshift Boots & Gear Lever Components

The gearshift lever boot is an important protective component within the classic Porsche 356 gearshift assembly. Positioned around the base of the gear lever, it helps prevent dirt, dust and moisture from reaching the internal linkage while maintaining the original appearance of the vehicle's interior.

After decades of use, original rubber boots can become hard, cracked or split, reducing their effectiveness and leaving the gearshift mechanism exposed to contamination. Replacing a deteriorated boot helps preserve the condition of the surrounding components and restores a clean, factory-style finish.

OE Match 99965901840 provides an original-style replacement for Porsche 356 and 356A models, making it suitable for routine repairs, interior refurbishment and complete vehicle restoration.

Featuring an internally threaded fitting and a smooth, rounded profile, the knob closely replicates the appearance of the original Porsche component. It is an ideal replacement for worn, cracked, damaged or missing gearshift knobs during routine maintenance or interior restoration.

What Does the Gearshift Knob Do?

The gearshift knob provides the driver's main contact point with the manual gear lever, allowing comfortable and controlled selection of gears.

Its rounded design offers a natural hand position, while the polished black finish complements the simple, classic interior styling of early Porsche models.

Why Does It Fail?

Although gearshift knobs are relatively simple components, they are exposed to constant handling and general wear.

Common causes of deterioration include:

Cracking or splitting through age Surface scratches and scuff marks Fading or discolouration Wear to the internal threads Loose fitting on the gear lever Damage from incorrect removal or installation

Older knobs may also lose their original polished appearance, making them look out of place in an otherwise restored interior.

When Should It Be Replaced?

Replacement is recommended when the original gearshift knob becomes cracked, loose, damaged or excessively worn.

A new OE Match knob is also an excellent finishing detail when restoring the dashboard, seats, carpets and other interior components of a classic Porsche.

Porsche 356B / 356C / 911 / 912 Gearshift Knobs & Interior Restoration Parts

The gearshift knob is a prominent feature of the classic Porsche interior, combining everyday functionality with the distinctive styling of early Porsche sports cars.

Over time, original gear knobs can become scratched, cracked, loose or discoloured. Replacing a worn knob with an original-style component helps restore the appearance and feel of the gear lever without changing the character of the interior.

The OE Match 69542419100 polished black gearshift knob is designed for selected Porsche 356B, 356C, early 911 and 912 models. Its traditional rounded profile, high-gloss finish and internally threaded mounting make it a suitable choice for period-style restoration and replacement.

Diagram ref no 8

The seal provides a barrier between the moving selector shaft and gearbox casing, helping retain the correct transmission oil level and protecting the surrounding components from oil contamination.

What Does the Gear Selector Shaft Oil Seal Do?

The gear selector shaft transfers movement from the gear lever linkage into the gearbox, allowing the driver to select different gears.

The oil seal fits around this shaft and prevents gearbox oil from escaping while allowing the shaft to move during gear changes. A properly functioning seal helps maintain the transmission oil level and keeps the gearbox exterior clean and dry.

Why Does It Fail?

Over time, the sealing material can harden, shrink or lose flexibility due to age, heat and prolonged contact with transmission oil.

Common causes of failure include:

• Age-related deterioration of the sealing lip
• Hardened or cracked rubber
• Wear from repeated selector shaft movement
• Corrosion or damage to the shaft sealing surface
• Incorrect installation or previous gearbox repairs
• Excessive shaft movement or wear

As the seal deteriorates, transmission oil may begin to seep around the selector shaft.

When Should It Be Replaced?

A replacement may be required if you notice:

• Gearbox oil leaking around the selector shaft
• Oil collecting on the underside of the transmission
• Drips beneath the gearbox
• A persistent oily residue around the selector linkage
• A damaged or hardened seal during gearbox servicing

The seal should also be inspected whenever the gearbox selector mechanism is dismantled or the transmission is removed for restoration.

Checks During Replacement

Before fitting a new oil seal, inspect the selector shaft for corrosion, scoring or excessive movement. Check the gearbox breather and surrounding seals to ensure the leak has been correctly identified.

The new seal should be installed squarely and to the correct depth, without damaging the sealing lip or shaft surface.

Porsche 911 / 912 Gearbox Oil Seals & Transmission Components

Gearbox oil seals are essential for maintaining the correct lubrication of classic Porsche manual transmissions. The gear selector shaft oil seal prevents transmission oil from leaking where the selector shaft enters the gearbox housing.

On older Porsche 911 and 912 models, ageing seals can become brittle or worn, allowing gearbox oil to escape. Replacing a leaking seal helps protect the transmission against lubricant loss and prevents oil contamination around the gear linkage and gearbox casing.

OE Match seal is a 15 × 24 × 7 mm replacement selector shaft oil seal for selected Porsche 911, 912 and 930 Turbo manual gearboxes. It is particularly suitable for maintenance and restoration of classic Porsche transmissions.

Boot For Coupler Shift Linkage In Transmission Tunnel, Outer.

The OE Match Outer Shift Coupler Boot is a replacement sealing sleeve for the gearshift linkage in the transmission tunnel of classic Porsche 911 and 930 Turbo models.

Fits:

• Porsche 911 1972-86 (Not for G50 Gearbox cars)
• Porsche 930 Turbo 1975-88

Diagram Ref No 33

Fitted around the shift coupler area, the flexible boot helps seal and protect the linkage where the gearshift mechanism runs through the transmission tunnel. It helps keep dirt, moisture and road contamination away from the coupler while also closing the surrounding tunnel opening.

Although the boot does not directly select gears, protecting the linkage is important because the shift coupler and its bushes must move freely and accurately to transmit movement from the gear lever to the gearbox.

What This Product Does:

• Covers the shift coupler linkage within the transmission tunnel area.
• Helps protect the coupler from dirt, dust and road contamination.
• Helps reduce moisture reaching the linkage and coupler components.
• Seals the opening around the gearshift linkage.
• Helps keep the coupler bushes and moving parts cleaner.
• Reduces direct exposure of the linkage to environmental contamination.
• Supports long-term operation of the gearshift linkage.
• Replaces a cracked, split, hardened or missing original boot.
• Helps restore the original transmission-tunnel sealing arrangement during restoration.

The boot acts primarily as a protective sealing component. It does not correct worn coupler bushes or gearbox faults, but it helps protect those components from contamination.

Symptoms Of Wear Or Failure:
Because this is a flexible rubber sealing component, deterioration is usually visible rather than producing a specific mechanical fault.

Possible signs include:

• Cracks in the rubber.
• Splits or tears in the boot.
• Rubber becoming hard or brittle.
• Boot losing its original shape.
• Loose fit around the linkage.
• Sections of the boot becoming detached.
• Missing boot discovered during servicing.
• Dirt or road debris accumulating around the shift coupler.
• Moisture reaching the linkage area.
• Increased transmission-tunnel noise or draughts where the seal is badly damaged.
• Contamination visible around the coupler bushes.
• Rubber breaking apart when disturbed during maintenance.

If poor gear selection, excessive gear-lever play or vague shifting is present, the shift coupler bushes, linkage adjustment and gearbox components should also be checked, because the boot itself is not normally responsible for shift precision.

Why Replacement Matters:
The shift coupler is an exposed moving part of the gear-selection linkage. Keeping contamination away from the mechanism helps maintain cleaner operating conditions around the bushes, clamp and linkage joints.

A torn or missing outer boot can allow:

• Dirt to collect around the coupler.
• Moisture to reach linkage components.
• Increased contamination of the bushes.
• Greater exposure of metal parts to corrosion.
• Noise and air movement through the transmission tunnel opening.
• Accelerated deterioration of surrounding components over time.

Replacing a damaged boot restores the intended protective barrier around the coupler.

Strainer For Ventilation. 

The OE Match Ventilation Strainer is a replacement screen filter for the fresh-air and cabin ventilation system of Porsche 356 B and Porsche 356 C models.

Fits:

• Porsche 356 B/C 1.6L 01/59-12/65

Diagram Ref No 22

Located at the passenger-compartment ventilation flap box, the strainer helps prevent larger debris, dirt and contaminants from entering the ventilation ducting while still allowing fresh air to pass through the system. It forms part of the original Porsche 356 ventilation arrangement and works alongside the flap control boxes, ducts and fresh-air inlet components.

Unlike a modern pollen or cabin filter, this component is primarily a screen-type strainer designed to stop larger particles and debris rather than provide fine filtration.

What This Product Does:

• Screens incoming ventilation air before it passes through the cabin airflow system.
• Helps prevent leaves, dirt and larger debris from entering the ventilation ducts.
• Helps keep the ventilation flap boxes and ducting cleaner.
• Allows fresh air to pass through while providing basic debris filtration.
• Helps maintain unobstructed ventilation airflow.
• Protects downstream ventilation components from contamination.
• Supports correct operation of the original Porsche 356 fresh-air system.
• Replaces a damaged, corroded, clogged or missing original strainer.
• Helps restore the original ventilation arrangement during vehicle restoration.

Parts diagrams place the strainer directly alongside the left and right ventilation flap control boxes, confirming its role within the Porsche 356 fresh-air distribution system.

Symptoms Of Wear Or Failure:
Possible signs that the strainer requires cleaning or replacement include:

• Reduced fresh-air flow through the cabin vents.
• Uneven airflow from the ventilation system.
• Visible accumulation of dirt, leaves or debris on the screen.
• Screen becoming heavily clogged.
• Torn or damaged mesh.
• Corrosion or deterioration of the strainer.
• Strainer becoming loose inside the ventilation housing.
• Rattling from the ventilation flap-box area.
• Debris entering the ventilation ducts or cabin.
• Missing sections of the screen.
• Distortion preventing the strainer from fitting correctly.
• A missing strainer discovered during restoration or ventilation-system servicing.

Reduced airflow can also be caused by blocked ducts, incorrectly adjusted ventilation flaps or damaged hoses, so the complete fresh-air system should be inspected where necessary.

Why Replacement Matters:
The ventilation strainer helps keep unwanted debris out of the fresh-air distribution system.

If the screen becomes clogged, airflow through the ventilation system can be restricted. If it becomes torn or is missing completely, leaves and other debris can enter the flap boxes and ducting.

Replacing a damaged or heavily contaminated strainer helps:

• Restore unrestricted fresh-air flow.
• Reduce debris entering ventilation ducts.
• Keep flap mechanisms cleaner.
• Prevent larger contaminants reaching the passenger compartment.
• Reduce the chance of debris causing rattles or obstruction.
• Restore the original ventilation-system configuration.
• Improve the quality of a detailed Porsche 356 restoration.
