Diagram Ref No 4

The oil level sender unit is responsible for monitoring the oil level within the tank and transmitting this information to the dashboard oil level gauge. The cork gasket creates a leak-free seal around the sender flange, preventing oil seepage while maintaining accurate oil level monitoring.

Although small and inexpensive, this gasket plays an important role in keeping the oil system properly sealed. During maintenance, sender replacement or oil tank restoration work, fitting a new gasket is highly recommended to prevent leaks and ensure reliable operation.

What Does an Oil Level Sender Unit Cork Gasket Do?

The gasket sits between the oil level sender unit and the oil tank mounting surface.

Its primary functions include:

  • Creating a leak-proof seal
  • Preventing oil seepage around the sender unit
  • Maintaining oil tank integrity
  • Supporting accurate oil level monitoring
  • Preventing contamination from entering the oil tank
  • Protecting surrounding engine bay components from oil leaks

A properly sealed sender unit helps maintain a clean engine bay and accurate oil system operation.

Why Do Oil Level Sender Gaskets Fail?

Cork gaskets naturally compress over time and are constantly exposed to oil, heat and vibration.

Common causes of failure include:

  • Age-related hardening
  • Compression set
  • Shrinkage over time
  • Heat cycling
  • Oil saturation
  • Improper installation
  • Damage during sender removal
  • Long-term storage deterioration

As the gasket loses elasticity, oil can begin to seep around the sender mounting flange.

When Should the Gasket Be Replaced?

The gasket should always be replaced whenever the oil level sender unit is removed.

Common signs of failure include:

  • Oil leaks around the oil tank sender unit
  • Oil residue on the oil tank
  • Oil staining in the engine bay
  • Perished or brittle gasket material
  • Sender unit removal during servicing
  • Oil tank refurbishment projects
  • Oil level sender replacement

Replacing the gasket during routine maintenance is inexpensive insurance against future oil leaks.

Why Replacement Matters

A leaking oil sender gasket may appear minor but can lead to persistent oil leaks and unnecessary mess within the engine bay.

Benefits of replacement include:

  • Prevents oil leaks
  • Maintains proper oil tank sealing
  • Protects engine bay components
  • Supports accurate oil level monitoring
  • Improves reliability
  • Reduces maintenance clean-up
  • Ideal for restoration projects
  • Restores factory sealing performance

For classic Porsche 911 models, maintaining the dry sump oil system is essential for both reliability and originality.

Oil Pipe Tank To Engine, 125cm.
The OE Match Oil Pipe Tank to Engine, 125cm is a high-quality replacement oil line designed for classic Porsche dry sump lubrication systems. This vital oil pipe connects the external oil tank to the engine, ensuring a continuous supply of oil for lubrication, cooling and engine protection.

Fits: 
  • Porsche 911 1965-1968 2.0L / 912 SWB (F)
  • Porsche 911 1968-1973 2.2L / 2.4L / 2.7L RS LWB (F) 

Diagram Ref No 17

Manufactured to OE specifications for fit, function and durability, this 125cm oil pipe is engineered to withstand the high temperatures, pressures and demanding operating conditions associated with air-cooled Porsche engines. It is an ideal replacement for ageing, corroded or leaking original oil lines, helping to maintain the integrity and performance of the lubrication system.

What This Product Does:
  • Transfers engine oil from the external oil tank to the engine.
  • Forms a critical part of the Porsche dry sump lubrication system.
  • Maintains a constant supply of oil to vital engine components.
  • Supports effective engine cooling through oil circulation.
  • Helps ensure proper oil pressure and lubrication performance.
  • Protects internal engine components from excessive wear.

Symptoms Of Wear Or Failure:
  • Visible oil leaks beneath the vehicle.
  • Oil seepage around pipe connections or fittings.
  • Corrosion or rust on metal sections of the pipe.
  • Cracked, perished or deteriorated hose sections.
  • Low engine oil levels due to leakage.
  • Oil pressure fluctuations or warning lights.
  • Burning oil smells from leaking oil contacting hot components.
  • Excessive oil contamination around the engine bay or underbody.

Why Replacement Matters:

  • Oil pipes are subjected to continuous exposure to hot engine oil, road debris, vibration, moisture and temperature fluctuations. Over time, corrosion, internal deterioration and physical damage can compromise the pipe's ability to safely transport oil throughout the lubrication system.
  • A leaking or restricted oil pipe can reduce oil pressure, cause oil starvation and increase engine operating temperatures, potentially leading to costly engine damage. Replacing a worn or ageing oil pipe helps maintain correct oil flow, protects critical engine components and ensures the lubrication system continues to operate efficiently. An OE Match replacement restores reliability, preserves engine performance and helps safeguard the longevity of your Porsche engine.

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.
