Engine Oil Tank - Stainless Steel

Restore an essential part of your Porsche 911 Turbo's dry-sump lubrication system with this OE Match replacement engine oil tank.

Fits:

• Porsche 911 1975-1977 3.0L Turbo (930)
• Porsche 911 1978-1989 3.3L Turbo (930)

Designed for the Porsche 911 930 Turbo 3.3L from 1977-89, the oil tank acts as the external reservoir for the engine's dry-sump lubrication system. A sound oil tank is essential for maintaining a reliable supply of clean engine oil, particularly on a high-performance air-cooled turbocharged engine.

An ideal replacement for an original tank suffering from corrosion, leaks, contamination or previous poor-quality repairs.

What Does the Oil Tank Do?

Unlike a conventional wet-sump engine where most of the oil is stored beneath the crankshaft, the Porsche 930 uses a dry-sump lubrication system with a separate external oil reservoir.

Oil scavenged from the engine is returned to the tank before being supplied back through the lubrication system.

The oil tank performs several important functions:

• Stores the engine's oil supply outside the crankcase
• Provides a consistent supply of oil to the lubrication system
• Helps separate air from returning engine oil
• Helps reduce oil aeration and foaming
• Supports effective oil circulation
• Contributes to engine oil temperature management
• Helps maintain reliable lubrication during acceleration, braking and cornering

For a high-performance turbocharged engine such as the Porsche 930, maintaining the condition of the complete lubrication system is particularly important.

Why Do Oil Tanks Fail?

Many original Porsche 930 oil tanks have now been in service for several decades. Age, heat, road contamination and moisture can eventually cause deterioration.

Common problems include:

• Internal corrosion caused by moisture
• External corrosion and rust
• Corrosion around seams and mounting points
• Oil leaks from weakened areas
• Damage around pipe and hose connections
• Internal sludge and contamination
• Physical damage from road debris
• Previous welding or poor-quality repairs
• General deterioration caused by age

Internal corrosion can be particularly difficult to identify because the outside of the tank may still appear serviceable while deterioration is occurring internally.

When Should the Oil Tank Be Replaced?

Replacement should be considered whenever the existing oil tank can no longer provide a clean, secure and leak-free reservoir for the engine's oil supply.

Typical signs include:

• Visible oil leaks
• Significant external corrosion
• Suspected internal rust
• Corrosion around seams or mounting points
• Damaged oil pipe connections
• Persistent contamination or sludge
• Previous repairs of questionable condition
• Physical damage to the tank
• During a major engine rebuild or vehicle restoration

A heavily corroded or contaminated tank should not be ignored. Debris entering the lubrication circuit can potentially damage expensive engine components, while a leaking tank can result in loss of engine oil.

Why Replace an Ageing Porsche 930 Oil Tank?

The dry-sump lubrication system is fundamental to the reliability of the air-cooled Porsche 911 Turbo engine.

Replacing a deteriorated original tank helps restore the integrity of the oil system and provides confidence that the engine's oil is being stored in a clean, secure and leak-free reservoir.

It is particularly worthwhile during an engine rebuild or restoration when the associated oil hoses, oil lines, thermostat, filter connections and seals can be inspected at the same time.

Oil Tanks & Dry-Sump Lubrication Parts

The Porsche 911 930 Turbo relies on its dry-sump lubrication system to provide a dependable supply of engine oil during normal driving and demanding high-performance use.

As these cars age, corrosion and contamination within the original oil tank can become an increasing concern. Replacing a deteriorated reservoir with an OE Match oil tank can help restore the integrity and reliability of this critical lubrication system.

When replacing the oil tank, it is also advisable to inspect the associated oil hoses, hard lines, fittings, oil thermostat, filter connections, breather hoses, seals and mounting hardware for deterioration or leaks.

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.
