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.

- 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.
