Gasket For Weber 40 Series 3 Barrel Carburettor.
The Porsche Gasket for Weber 40 Series 3-Barrel Carburettor is a genuine OEM replacement part designed for classic Porsche models fitted with Weber 40 IDA 3-barrel carburettors. This gasket provides a reliable seal between carburettor components, preventing air or fuel leaks and ensuring your engine runs smoothly and efficiently.

Fits:
  • Porsche 911 1965-1968 2.0L / 912 SWB (F)
  • Porsche 911 1970-1971 2.2L / 2.4L / 2.7L RS LWB (F)
  • Porsche 914 (1970-1976)

What This Product Does:

  • Forms a sealed connection between parts of the carburettor assembly (for example between sections of the carb body, base, bowls etc.), preventing air or fuel leaks. This ensures the carburettor internal pressures, fuel/air mixture, and fuel delivery stay as designed.
  • Helps maintain vacuum and avoids unmetered air entering the mix, which would upset the air-fuel ratio.
  • Keeps fuel/air paths, float chambers, and throttle linkage parts sealed so the carburettor performs reliably and efficiently.

Symptoms Of A Worn Or Failing Gasket:
If this gasket is leaking or degraded, you might notice:
  • Rough idle or unstable idle because air leaks introduce unmeasured fresh air, upsetting the mixture.
  • Hesitation on acceleration or lean-running behavior, especially when the engine is under load.
  • Backfiring or popping in exhaust/intake due to incorrect mixture or vacuum leaks.
  • Fuel smell or visible fuel seepage near the carburettor seams.
  • Higher fuel consumption or poor economy due to less efficient combustion.
  • Difficult starting, especially when cold, because gasket leaks can make mixture control harder.

Why Replacement Matters:
A correct gasket ensures the carburettor works as intended: stable mixture, good performance, reliable idle, and safe fuel sealing.
Prevents damage: leaks can allow dirt or debris into the carburettor or intake, potentially damaging internal parts.
Helps maintain emissions and driveability. Classic cars are particularly sensitive to small leaks.
Uses the OEM specification so fit, material, sealing properties are correct, preserving originality and value for restorations.

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.

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.
