A Quick Look at Porsche

Porsche information on this page is based on details supplied by the manufacturer or distributor, plus any OE references provided with the parts.

Choosing the Right Fit for Your Porsche

Where Porsche is listed for Porsche, use the supplied model coverage and OE references to confirm suitability. Check details that commonly affect fitment such as model year, side/position, and connector type where relevant.

  • Typical reasons people replace these parts include maintaining originality, keeping factory specification, and choosing the latest genuine revisions for peace of mind.
  • Common real-world issues behind many Porsche repairs are age and mileage: oil leaks, cooling system fatigue, brake and suspension wear, corrosion and electrical faults from moisture or heat cycling.
  • Before ordering, confirm part numbers against VIN or option/PR codes, especially for safety‑critical or complex components.
  • When upgrading, decide whether you want pure originality or performance changes, as some aftermarket options may suit specific goals better than genuine.
  • For bigger jobs, replace related seals, hardware and consumables at the same time to avoid repeat labour and compatibility issues.
  • Where available, follow the manufacturer’s fitting and bedding‑in guidance to get the best performance and longevity.

Browse by Category

If you already know the area you are working on, start with the category and then filter by Porsche model. Where real-world symptoms and typical reasons to replace are provided, use them to keep the wording grounded.

Brakes — Brake components are renewed to restore stopping performance, address wear or upgrade a Porsche for fast road or track use. Common symptoms include: Common symptoms include vibration under braking, increased stopping distances, squealing, pulling to one side, warning lights and visible wear to discs and pads.

  • Check whether the parts are OE-equivalent replacements or performance upgrades and match this to how the Porsche is used.
  • Follow any recommended bedding-in procedure and consider replacing discs, pads, sensors and fitting hardware together where advised.

Clothing & Gifts — Porsche-themed clothing and gifts let owners and enthusiasts show their passion off the road, or make ideal presents for fans of the marque. Common symptoms include: Items may become worn, faded, damaged or go out of style, prompting replacement with newer designs.

  • Review available size, colour and material details to help choose the right item and ensure it matches how it will be used.
  • Check any care or washing guidance so garments and accessories keep their appearance for longer.

Lifestyle — To explore different Porsche-inspired lifestyle products or gift ideas. Common symptoms include: General wear from handling or display.

  • Confirm whether items are official Porsche lifestyle products or from trusted partner brands where stated.
  • Consider who the item is for and how it will be used day to day to select the most suitable style or product type.

Keyring — To choose a different design, material or model theme. Common symptoms include: Scratches, worn finishes or loose fittings.

  • Keyrings make simple, practical Porsche-themed gifts and can be matched to specific models or heritage designs where available.
  • If a keyring shows damage or looseness, replace it to avoid losing keys or further wear to finishes.

Product Information
Product Information

This 0.50 mm copper cylinder-head base gasket by Porsche is intended for selected early Porsche 911 engine applications from 1965 to 1973, including specified 2.0L, 2.2L, 2.4L and 2.7L RS variants. It is used within the cylinder and cylinder-head assembly during engine rebuilding or sealing work.

Fits:
Porsche 911 1965-73

Diagram ref no: 26


What This Product Does

The gasket provides a precisely sized sealing layer at the cylinder base. Its specified thickness helps maintain the intended cylinder installation dimensions while sealing the joint against oil leakage. Correct gasket selection is important whenever cylinders are removed, inspected or refitted during an engine overhaul.


Functions

  • Seals the joint at the base of the engine cylinder
  • Supports the specified cylinder installation height
  • Helps prevent oil seepage from the cylinder-base area
  • Provides a replaceable sealing surface during engine assembly
  • Supports accurate reassembly of the cylinder and piston installation


Technical Details

  • Manufacturer: Porsche
  • Reference number: 90110419102
  • Material: copper
  • Specified thickness: 0.50 mm

Symptoms of Fault

  • Oil seepage visible around the cylinder-base joint
  • A flattened, marked or damaged gasket found during dismantling
  • Persistent engine oil leakage after accessible external seals have been checked
  • Incorrect cylinder installation measurements during an engine build
  • Evidence of fretting, corrosion or an uneven sealing surface when the engine is stripped


Why Replacement Matters

A compressed or damaged base gasket may no longer seal consistently after the cylinder has been removed. Renewing the gasket during rebuilding helps reduce the risk of repeat oil leaks and avoids another engine strip-down to correct a compromised joint. The 0.50 mm specification should only be used where it matches the engine configuration and measured build requirements. Related sealing surfaces, cylinders, pistons, rings and engine hardware should also be inspected while access is available.


OE Reference

  • 90110419102
  • 901 104 191 02
  • 901.104.191.02


FAQs

  • When should this gasket be renewed?
    It is normally replaced when the relevant cylinder is removed during an overhaul, or when damage or leakage is found at the base joint.
  • Can a different gasket thickness be substituted?
    The selected thickness affects engine assembly dimensions. Use the specification required by the engine configuration and measured rebuild clearances.
  • What should be checked at the same time?
    Inspect the sealing faces, cylinders, pistons, rings, oiling system and associated hardware before reassembly.
  • Does every oil leak indicate a failed base gasket?
    No. Oil can travel from other seals or joints, so the source should be confirmed before dismantling the engine.

Cylinder head copper base gasket 0.25mm
Copper 0.25mm cylinder base gasket by Porsche for selected Porsche 911 models from 1965–73 and the 914-6 from 1970–76. This gasket fits between the cylinder barrel and engine crankcase during flat-six engine assembly.
Sold each

Fits:
Porsche 911 1965 - 1973
Porsche 914-6 1970 - 1976

Diagram ref no 26


What This Product Does

The gasket seals the joint at the base of the cylinder while maintaining the specified spacing between the cylinder and crankcase. Its thickness contributes to cylinder positioning and must be considered when measuring deck height and rebuilding the engine.


Functions

  • Seals the cylinder-to-crankcase joint
  • Provides a controlled 0.25mm base thickness
  • Supports correct cylinder positioning during assembly
  • Helps prevent oil seepage around the cylinder base
  • Forms part of the sealing system for each cylinder


Technical Details

  • Porsche reference: 90110419100
  • Material: copper
  • Thickness: 0.25mm
  • Inner diameter: approximately 92.2mm
  • Outer diameter: approximately 103mm
  • Required quantity for a complete flat-six engine: 6

Internal application data also identifies use with 911 T-E/E, 911 T-V and 911 T-K engine or model variants. Confirm the required gasket thickness through the appropriate engine measurements before assembly.


Symptoms of Fault

  • Oil seepage visible around the cylinder-to-crankcase joint
  • A flattened, distorted or damaged gasket found during dismantling
  • Previous use of unsuitable sealant around the cylinder base
  • Incorrect cylinder height or deck measurements during an engine rebuild


Why Replacement Matters

A cylinder base gasket can become compressed or damaged after installation and should be inspected whenever the cylinders are removed. Installing the specified gasket helps restore the intended cylinder spacing and sealing arrangement. During a full rebuild, all cylinders should be measured and assembled consistently, with related seals, hardware and wear components checked while access is available.


OE Reference

  • 90110419100
  • 901.104.191.00


FAQs

  • How many gaskets are required?
    Diagram data specifies six for a complete flat-six engine. Confirm the quantity needed for the work being undertaken.
  • Can an old cylinder base gasket be reused?
    Replacement is advisable once the cylinder has been removed because the installed gasket may be compressed or distorted.
  • Does gasket thickness matter?
    Yes. Base-gasket thickness affects cylinder positioning and should match the engine measurements and rebuild specification.
  • What should be checked during installation?
    Inspect the cylinder and crankcase mating surfaces, verify deck measurements and check the associated seals and hardware.

Check fitment for your specific vehicle, model year and engine before ordering.
