Stainless Steel Engine Oil Tank
Restore an essential part of your early Porsche 911's
dry-sump lubrication system with this OE Match Stainless Steel Engine Oil Tank. This oil tank is ideal for replacing an original tank
suffering from corrosion, leaks, contamination or previous repairs.

This early-style tank uses the original arrangement where the engine oil is filled from inside the engine bay and is suitable for non-Sportomatic models.
What Does the Oil Tank Do?
The classic air-cooled Porsche 911 uses a dry-sump lubrication system. Rather than storing the majority of its engine oil in a conventional sump underneath the engine, the oil is held in a separate external reservoir.
Oil is scavenged from the engine and returned to the tank before being circulated through the lubrication system again.
The oil tank performs several important functions:
- Stores the engine's main oil supply
- Provides a consistent supply of oil to the engine
- Helps separate air from returning engine oil
- Helps reduce oil aeration and foaming
- Supports reliable lubrication during cornering, acceleration and braking
- Forms an essential part of the engine's oil circulation system
- Contributes to effective oil and engine temperature management
A clean, structurally sound and leak-free oil tank is therefore essential to the reliability and longevity of the air-cooled flat-six engine.
Why Choose a Stainless Steel Replacement?
Corrosion is one of the biggest problems affecting original early Porsche 911 oil tanks.
Stainless steel provides increased resistance to corrosion compared with conventional mild-steel construction, making it an excellent choice for classic Porsche restorations and cars intended for continued long-term use.
It provides the opportunity to replace a decades-old reservoir while retaining the correct function of the original dry-sump lubrication system.
Why Do Oil Tanks Fail?
Original Porsche 911 oil tanks from this period are now more than 50 years old. Even tanks that appear serviceable externally can suffer deterioration internally.
Common causes of failure include:
- Internal corrosion caused by moisture
- External rust and corrosion
- Deterioration around seams and welded joints
- Corrosion around mounting points
- Oil leaks from weakened areas
- Damage around hose and pipe connections
- Internal sludge and contamination
- Physical damage
- Previous welding or poor-quality repairs
- General deterioration caused by age
Internal corrosion is particularly important because rust and contamination can potentially enter the engine's lubrication system.
When Should the Oil Tank Be Replaced?
Replacement should be considered whenever the existing tank can no longer provide a clean, secure and leak-free reservoir for the engine oil.
- Typical warning signs include:
- Visible oil leaks
- Significant external corrosion
- Suspected internal rust
- Corrosion around seams or mounting points
- Damaged pipe or hose connections
- Persistent internal contamination or sludge
- Previous repairs of questionable quality
- Physical damage or deformation
- During a complete vehicle restoration
- During an engine rebuild where contamination of the new engine must be avoided
Replacing a questionable oil tank during an engine rebuild is particularly worthwhile, as it prevents old contamination or corrosion debris from being introduced into a freshly rebuilt engine.

OEMatch Oil Tank — Fit, Function, Confidence
Oil tanks play a central role in Porsche lubrication systems by storing, circulating and helping to cool engine oil. In dry-sump layouts they also allow lower engine placement while ensuring steady oil delivery under varying loads. OEMatch supplies oil tank options catalogued for Porsche models to support application-specific needs.
Understanding OEMatch Oil Tank
OEM (Original Equipment Manufacturer) parts are made by the same company that produced your Porsche’s original oil tank. OE (Original Equipment) refers to parts matching original specifications for the oil tank and may be supplied by alternative manufacturers. Aftermarket parts offer alternative options, sometimes with enhanced features or better value. OEMatch supplies non-OEM oil tank engineered as direct-fit alternatives to OEM parts, made to original-spec dimensions and tolerances for Porsche models. Oil tanks store and circulate engine oil, separate air from oil to reduce foaming, and assist temperature regulation so bearings and moving parts receive steady lubrication. OEMatch maintains an extensive Porsche parts catalogue with thousands of part numbers and many OE cross-references to help identify compatible replacements; this coverage helps when matching tanks, breather components, seals and fittings to specific model requirements.
Benefits Include
- Restored oil circulation and pressure stability to protect bearings and camtrain components.
- Improved oil temperature control and reduced overheating risk under sustained load.
- Reduced foaming and improved oil film stability through effective air separation.
- Replacement seals and fittings lower the risk of external leaks and contamination.
Why Oil Tank Wear and Fail
- Cracks or leaks from vibration, impact or old mounting points.
- Corrosion from moisture, condensation or degraded oil.
- Blocked breathers or vents causing pressure imbalance and reduced flow.
- Internal contamination such as sludge or metal debris impairing circulation.
The Importance of Replacing with OEMatch Oil Tank
A leaking or damaged oil tank can lead to oil loss, low pressure or poor cooling, increasing the risk of severe engine damage. Timely replacement restores correct oil flow and pressure, prevents oil starvation and helps maintain reliable lubrication under road or track conditions. Where components affect pressure, breathers or sensor interfaces, check mounting, seals and associated hoses during replacement and follow model-specific procedures for installation and inspection.
Advantages
- Manufactured to original-spec dimensions and tolerances so units fit original mounting points and clearances.
- Materials and construction chosen to resist corrosion and mechanical stress, including high-grade alloys or reinforced composites where specified.
- Catalogued references and cross-checks to simplify selection for Porsche models and related breather, seal and hose parts.
