We supply high-quality replacement oil tank hardware crafted to the same dimensional standards as the original Porsche components. Manufactured from durable, corrosion-resistant materials, these washers are designed to withstand continuous exposure to oil, heat, and pressure—making them ideal for classic Porsche maintenance and restorations.

What Does the Oil Tank Mounting Kit Do?

Each component in this kit works together to secure the oil tank and maintain stable dry-sump operation.

Core Functions:

  • Provides secure mounting and vibration resistance for the oil tank.
  • Ensures even load distribution across mounting points.
  • Maintains tank alignment for correct oil line routing.
  • Prevents leaks by keeping the tank firmly compressed against mounting surfaces.
  • Supports lubrication stability during high-performance driving.

These hardware components are crucial for maintaining the stability and efficiency of Porsche’s iconic dry-sump system.

Why Do Oil Tank Mounting Components Fail?

Over decades of use—especially in classic Porsches—mounting hardware faces extreme conditions including heat, vibration, oil exposure, and corrosion.

Common Causes of Failure Include:

  • Corrosion from moisture, road debris, and oil residue.
  • Thermal cycling, weakening metal components over time.
  • Vibration fatigue, causing washers or nuts to deform.
  • Aged threads leading to poor clamping force.
  • Loss of tension from worn or compressed washers.

When mounting components weaken or degrade, the oil tank can shift, vibrate, or leak—posing risks to lubrication pressure, engine longevity, and overall performance.

Why Replace or Upgrade Your Porsche Oil Tank Mounting Kit?

Restoring your oil tank hardware ensures safe, leak-free operation and preserves the integrity of Porsche’s dry-sump lubrication system.

Key Benefits:

  • Restores correct oil tank positioning and stability.
  • Prevents oil leaks and vibration-related wear.
  • Ensures secure fitment with high-quality hardware.
  • Compatible with Porsche 911 (1965–89) and 914-6.
  • Ideal for maintenance, restoration, and rebuild projects.
  • Exact-fit replacement designed to match original specifications.

This kit is essential for owners seeking long-term reliability and authenticity in classic Porsche lubrication systems.

We supply high-quality replacement oil tank mounting washers crafted to the same dimensional standards as the original Porsche components. Manufactured from durable, corrosion-resistant materials, these washers are designed to withstand continuous exposure to oil, heat, and pressure—making them ideal for classic Porsche maintenance and restorations.

What Does the Oil Tank Mounting Washer Do?

The oil tank mounting washer plays a crucial role in your Porsche’s lubrication and engine stability system.

Core Functions:

  • Secures the oil tank to the chassis mounting points.
  • Distributes load evenly across the mounting area.
  • Prevents vibration and movement during operation.
  • Ensures proper sealing against leaks or oil seepage.
  • Maintains correct alignment for oil line connections.

Without a properly functioning washer, the oil tank can shift slightly, leading to unwanted vibrations, stress on oil fittings, or even oil leaks that compromise system pressure.

Why Do Oil Tank Mounting Washers Fail?

Despite their small size, mounting washers endure extreme conditions—heat, vibration, and oil exposure. Over time, this can lead to wear and failure.

Common Causes of Failure Include:

  • Thermal fatigue from repeated heat cycles.
  • Corrosion caused by prolonged contact with oil and moisture.
  • Metal fatigue from vibration or overtightening.
  • Deformation or cracking due to age or mechanical stress.
  • Loss of elasticity or tension affecting mounting stability.

When a washer becomes worn or corroded, it can no longer secure the tank properly—potentially leading to oil leaks, vibration noise, or tank misalignment.

Why Replace or Upgrade Your Oil Tank Mounting Washer?

Replacing a worn or damaged oil tank mounting washer restores secure fitment and ensures the integrity of your oil system. This simple yet essential component helps prevent larger mechanical issues and supports consistent lubrication performance.

Key Benefits:

  • Restores proper oil tank stability and alignment.
  • Prevents vibration, leaks, or stress on mounting bolts.
  • Maintains efficient oil system pressure and performance.
  • Manufactured to precise Porsche specifications for accurate fit.
  • Constructed from high-grade, oil- and heat-resistant material.
  • Ideal for Porsche 911 (1965–1989) and 914-6 restoration or maintenance.

Our Design911 mounting washers deliver reliable, long-lasting performance—perfect for enthusiasts maintaining classic Porsche engineering precision.

Highlights

  • Designed for Porsche 911 (1965–1989) and Porsche 914-6 models.      
  • Precision-fit replacement washer for oil tank mount.
  • Crafted from high-strength, corrosion-resistant materials.
  • Withstands high temperatures and oil exposure.
  • Essential for dry-sump system reliability.
  • Ideal for restoration, maintenance, or preventative servicing.

About Oil Tank & Parts

Oil Tanks & Parts – Precision Lubrication Storage for Porsche Performance

The engine oil tank is a vital component in Porsche’s dry-sump lubrication system, designed to store and manage oil separately from the crankcase. Unlike traditional wet-sump setups, this system ensures consistent oil pressure, efficient cooling, and superior lubrication under all driving conditions — from spirited road use to high-performance track sessions.

At Design911, we offer a wide range of engine oil tanks, fittings, and associated components for Porsche models, both classic and modern. Built from high-grade aluminium, steel, and corrosion-resistant materials, our products are designed for durability, temperature stability, and optimal oil management.

Whether you’re maintaining an air-cooled 911 or servicing a contemporary GT model, our oil tanks and parts guarantee the reliability and performance your engine deserves.

What Do Oil Tanks & Components Do?

The oil tank serves as the reservoir in a dry-sump lubrication system, allowing continuous oil flow to the engine while preventing aeration or starvation during hard acceleration, braking, or cornering.

Core Functions:

  • Stores and circulates oil independently from the engine block.
  • Maintains stable oil pressure and temperature for consistent lubrication.
  • Prevents oil starvation during high-performance driving.
  • Aids in cooling, helping regulate operating temperatures.
  • Separates air and oil, preventing foaming and pressure loss.

Supporting components — such as oil tank fittings, caps, hoses, and mounts — ensure secure flow, sealing, and performance integrity across the entire lubrication circuit.

Why Do Oil Tanks & Parts Fail?

Over time, exposure to heat, pressure, and vibration can cause the oil tank and its associated components to degrade or leak, compromising the lubrication system.

Common Causes of Failure Include:

  • Corrosion or internal contamination from moisture or sludge build-up.
  • Cracks or punctures caused by vibration or impact.
  • Oil leaks from damaged seals, caps, or connections.
  • Blockages in breather or feed lines affecting oil circulation.
  • Heat stress, leading to material fatigue or deformation.

Typical symptoms include oil leaks, fluctuating oil pressure, overheating, or unusual engine noise — all signs that inspection or replacement is required.

Why Replace Oil Tank Components?

Replacing a worn or leaking oil tank ensures your Porsche’s lubrication system remains efficient and protected. Our precision-engineered oil tanks and accessories are designed to deliver superior durability, sealing, and performance under high stress.

Key Benefits:

  • Restores stable oil pressure and circulation.
  • Prevents leaks and contamination.
  • Enhances oil cooling efficiency and consistency.
  • Constructed from corrosion-resistant, heat-stable materials.
  • Direct-fit compatibility with a wide range of Porsche engines.
  • Ideal for restorations, rebuilds, and performance applications.

A properly maintained oil tank system is essential for ensuring engine longevity and reliability — particularly in performance and motorsport use.

Highlights:

  • Precision-engineered Porsche oil tanks and associated components.
  • Designed for consistent oil pressure and temperature control.
  • Durable materials for heat and corrosion resistance.
  • Direct-fit solutions for 911, Cayman, Boxster, GT models and more.
  • Perfect for rebuilds, restorations, and performance upgrades.
  • Ensures optimal lubrication and engine reliability.
