Engine Cylinder Base Gasket 0.50mm
for early Porsche air-cooled flat-six engines, including the 911 and 930 Turbo. This OE Match replacement is built to original Porsche specifications, matching the factory dimensions, thickness, and sealing quality for a perfect fit. Positioned between the crankcase and cylinder base, it provides a reliable seal to prevent oil and combustion leaks, ensuring lasting engine integrity and performance.

Fits:
Porsche 911 3.0ltr - 1976 to 1977
Porsche 911 3.0ltr / 3.2ltr - 1978 to 1989
Porsche 911 turbo 3.0ltr - 1975 to 1977

Diagram Ref No 5.

Position on Car: Between engine block (crankcase) and cylinder base in air-cooled engine.

Over time the cylinder‐base gasket can degrade due to thermal cycling, vibration and age, leading to oil seepage, reduction in compression sealing or potential engine case contamination. Replacing it with a high-quality replacement gasket ensures the joint is properly sealed, avoids loss of performance and prevents possible engine damage.

Replace when:
You are performing an engine rebuild or cylinder removal.
 You detect oil seepage or visible signs of leakage from the cylinder base area.
 You observe compression loss, or gasket part numbers are referenced in service documentation for your engine variant.

F/HG3400H/300M
Product Information
Product Information
Hylomar Gasket 3400 is a modified anaerobic curing, flexible sealant designed to become a Formed in Place (FIP) Gasket when cured. The cured compound has good temperature resistance and high resistance to fretting. The cure is initiated when the compound is in contact with metal ions and in anaerobic conditions. The cure rate and final strength is dependent on the metals being joined and the temperature at which the component is used. The heat generated by a running engine will accelerate the cure.

Typical Applications
Hylomar Gasket 3400 can be used as a gasketing compound between machined surfaces. It is ideal for sealing between mating faces on engines and transmission components where resistance to temperature and vibration are essential.

INSTRUCTIONS FOR USE
Hylomar Gasket 3400 should be applied to clean and dry surfaces, free of contamination such as oil or grease. The compound may be dispensed by hand from cartridge, concertina pack, or via a screen printing system. Once applied the joint should be assembled as soon as practical. Any excess compound can be easily wiped off external surfaces with a clean cloth soaked in Acetone or other suitable solvents.

Product Information
Product Information
Inlet / Intake Manifold Gasket.
Flat intake manifold gasket it used between the intake manifold runners and the cylinder head on Porsche flat-six engines. Each gasket seals one intake port pair; a complete engine typically uses six of them.
Sold each, 
typically 6 required per car.

Fits:
Porsche 911 1974 - 1983  - 6pcs required


Diagram ref no 7.

This gasket provides a gas-tight seal at the intake manifold interface so that all air entering the engine passes through the intended metered path (CIS / fuel injection system). By preventing air leaks at the manifold flange, it:
•  Maintains correct mixture and idle quality
•  Supports smooth throttle response and drivability
•  Helps avoid lean conditions that can lead to higher combustion temperatures.

Over time, intake manifold gaskets can harden, shrink or crack due to heat cycles, fuel vapour and age. When they fail:
 The engine may draw in unmetered air, causing rough idle, poor cold running or lean mixture.
  You can experience hesitation, popping, or flat spots under acceleration.
  Vacuum leaks can make tuning and diagnostics difficult and may increase fuel consumption.
Replacing old gaskets with fresh restores correct sealing, stabilises idle and mixture, and helps the engine run as intended.

When to replace
Consider replacing the inlet manifold gaskets if:
 You’re rebuilding or refreshing the top end of the engine.
 There are suspected vacuum leaks around the intake manifold.
 The engine has rough idle, hunting, or lean codes/symptoms not traced to other components.
 The original gaskets are visibly cracked, brittle, or oil/fuel soaked.
 You are converting, upgrading or servicing the CIS / intake system on a classic 911 or 930.

About Gaskets & Sets

Engine Gaskets & Gasket Sets – Precision Sealing for Porsche Engines

Engine gaskets are vital components that ensure your Porsche’s engine operates efficiently and leak-free. Positioned between key engine surfaces such as the cylinder head, intake manifold, and oil pan, gaskets maintain a perfect seal against high temperatures, pressures, and fluids.

At Design911, we offer a comprehensive range of engine gaskets, seals, and complete gasket kits for Porsche models of every generation. Each gasket is crafted from high-quality composite, metal, or elastomer materials to withstand the extreme conditions of high-performance engines — ensuring optimal sealing, reduced oil and coolant leaks, and consistent compression.

Whether you’re rebuilding a classic 911 flat-six or servicing a modern turbocharged Porsche engine, our manufacturer-quality gaskets and complete kits guarantee reliability, performance, and peace of mind.

What Do Engine Gaskets and Gasket Sets Do?

Gaskets play a critical role in ensuring that various engine systems — combustion, lubrication, and cooling — remain properly sealed.

Core Functions:

  • Prevent leaks of oil, coolant, air, and combustion gases.
  • Maintain compression between the engine block and cylinder head.
  • Ensure efficient combustion and proper engine pressure balance.
  • Protect internal components from cross-contamination of fluids.

A properly sealed engine not only improves performance and efficiency but also prevents costly long-term damage.

Why Do Gaskets Fail?

Despite their durability, gaskets naturally degrade over time due to extreme heat cycles, pressure variations, and material fatigue.

Common Causes of Gasket Failure Include:

  • Overheating, causing warping or breakdown of the gasket material.
  • Improper installation or torqueing during assembly.
  • Aging materials that harden or crack with use.
  • Chemical degradation from oil or coolant exposure.
  • Uneven pressure or engine vibration, leading to micro-leaks.

Typical symptoms of gasket failure include oil or coolant leaks, reduced compression, overheating, or visible residue at gasket joints.

Why Replace with Precision-Engineered Gaskets and Kits?

Replacing worn or leaking gaskets is essential to maintain proper engine compression, prevent contamination, and restore overall reliability. Our direct-fit gasket sets and kits are designed to meet or exceed Porsche engineering standards, providing complete sealing solutions for rebuilds and maintenance.

Key Benefits:

  • Restores proper sealing and compression integrity.
  • Prevents oil and coolant leaks for cleaner performance.
  • Enhances efficiency and reliability under load.
  • Manufactured from high-grade, heat- and pressure-resistant materials.
  • Available as individual gaskets or complete kits for full rebuilds.
  • Direct-fit compatibility for a wide range of Porsche models.

Our gasket sets are ideal for engine rebuilds, overhauls, and preventive maintenance, ensuring long-term dependability and peak performance.

Highlights:

  • Complete Porsche engine gasket kits and individual components.
  • Precision-engineered for exact sealing performance.
  • Constructed from advanced composite, metal, and elastomer materials.
  • Resistant to heat, pressure, and chemical exposure.
  • Suitable for classic air-cooled and modern water-cooled engines.
  • Ensures leak-free operation and lasting reliability.
