Engine Oil Tank 

Restore the heart of your classic Porsche's dry sump lubrication system with this OE Match Oil Tank, developed for the legendary Porsche 911 RSR 2.8 and 3.0 litre race cars. Manufactured to OE specifications, this premium replacement faithfully reproduces the original design, providing factory-style fitment, correct oil capacity and dependable performance for restoration and historic motorsport applications.

Fits:

  • Porsche 911 RSR 2.8ltr
  • Porsche 911 RSR 3.0ltr

This oil tank is engineered to meet the demands of high-performance air-cooled flat-six engines, ensuring a reliable oil supply under both road and competition conditions. Whether you're rebuilding an authentic RSR, restoring a historic race car or maintaining a high-value classic Porsche, this oil tank delivers the quality and accuracy expected from an OE Match component.

What Does the Oil Tank Do?

Unlike a conventional wet sump engine, the Porsche 911 RSR uses a dry sump lubrication system, with the oil tank acting as a separate oil reservoir.

The oil tank stores the engine's oil supply before it is circulated throughout the lubrication system. It also helps separate air from the returning oil, promotes cooling and ensures a consistent oil supply during high cornering, braking and acceleration forces.

A correctly functioning oil tank helps provide:

  • Consistent engine oil supply
  • Stable oil pressure
  • Efficient oil cooling
  • Effective oil de-aeration
  • Reliable lubrication during high-performance driving
  • Long-term engine protection
  • Proper operation of the dry sump lubrication system

Why Replace the Oil Tank?

After decades of use, original oil tanks can suffer from corrosion, internal contamination or physical damage that compromises both reliability and engine protection.

Replacement may be necessary due to:

  • Internal corrosion
  • External rust
  • Accident damage
  • Fatigue cracking
  • Damaged mounting points
  • Previous repairs
  • Contaminated internal surfaces
  • Distorted oil pipe connections
  • Oil leaks
  • Restoration requirements

Replacing the oil tank during an engine rebuild or vehicle restoration helps ensure the lubrication system performs exactly as intended.

Symptoms of a Damaged Oil Tank

A replacement oil tank should be considered if you notice:

  • Oil leaks from the tank
  • Corrosion around seams or welds
  • Damaged mounting brackets
  • Cracked or dented tank body
  • Oil contamination
  • Loose oil connections
  • Persistent oil seepage
  • Physical damage following impact
  • Signs of previous poor-quality repairs

Any signs of corrosion inside the oil tank should be addressed immediately, as debris can circulate throughout the engine and cause extensive internal damage.

Benefits

Installing this OE Match oil tank helps to:

  • Restore correct oil system operation
  • Maintain stable oil pressure
  • Improve lubrication reliability
  • Replace corroded or damaged original tanks
  • Reduce the risk of oil leaks
  • Preserve factory appearance
  • Support authentic
  • RSR restorations
  • Protect valuable engine components
  • Enhance long-term reliability
  • Maintain the integrity of the Porsche dry sump lubrication system

Installation Recommendations

Professional installation is strongly recommended.

During installation, inspect:

  • Oil lines
  • Flexible oil hoses
  • Oil thermostat
  • Oil filter console
  • Oil pressure relief valve
  • Oil level sender
  • Oil tank mounting rubbers
  • Tank retaining hardware
  • Engine oil cooler
  • Oil breather hoses
  • Seals and gaskets

Flush the lubrication system before installation to remove contaminants from previous components.

As the oil tank gasket ages, it becomes brittle, compressed, or cracked from heat cycles and vibration. This leads to oil seepage around the tank area, creating drips beneath the car, engine-bay contamination, and potential loss of oil pressure. Replacing the gasket restores a proper seal, prevents oil leaks, and helps maintain the health and cleanliness of the lubrication system.

Replace the oil tank gasket when:
• You notice oil drips or seepage around the oil tank
• The gasket appears dry, brittle, cracked, or crushed
• The oil tank is being serviced or removed
• You smell oil fumes from the rear right side of the vehicle
• Oil pressure seems inconsistent due to possible leakage
• Performing a restoration or major engine/oil system refresh

About Oil Tank

Engine Oil Tanks – Reliable Lubrication and Temperature Control for Porsche Engines

Engine oil tanks are a vital component in Porsche’s high-performance lubrication systems, especially in models equipped with dry-sump or performance-oriented engines. These tanks store, circulate, and cool engine oil, ensuring the correct oil pressure and temperature are maintained under all driving conditions - from everyday use to track performance.

At Design911, we supply a wide range of genuine and high-quality engine oil tanks for Porsche models including 911, Boxster, Cayman, Cayenne, Macan, and Panamera. Each tank is designed to match the factory’s engineering precision, providing exceptional oil flow, pressure control, and durability to keep your Porsche performing at its best.

What Do Engine Oil Tanks Do?

The engine oil tank forms the heart of your Porsche’s lubrication system, performing several key roles:

  • Stores and circulates engine oil to maintain a continuous supply under all conditions.
  • Separates air and oil to prevent foaming and maintain oil pressure.
  • Assists in temperature regulation, allowing excess heat to dissipate efficiently.
  • Ensures optimal lubrication for engine components, reducing friction and wear.

In Porsche’s dry-sump systems, the oil tank is particularly important — allowing the engine to sit lower for better handling while ensuring consistent oil delivery even under high G-forces.

Why Do Engine Oil Tanks Fail?

While designed for long-term reliability, engine oil tanks can deteriorate or fail over time due to mechanical stress, corrosion, or contamination. Common causes include:

  • Cracks or leaks from vibration or impact damage.
  • Corrosion caused by moisture, condensation, or old oil residue.
  • Blocked breather systems leading to pressure imbalance.
  • Internal contamination from sludge or metal debris.
  • Deteriorated seals or fittings causing oil leaks or pressure loss.

Signs of failure may include visible oil leaks, fluctuating oil pressure readings, or an oil smell around the engine bay.

Why Replace a Faulty Engine Oil Tank?

A damaged or leaking oil tank can cause oil loss, low pressure, or poor cooling — all of which risk severe engine damage. Replacing a faulty tank ensures consistent oil supply, stable pressure, and optimal engine protection.

Benefits of replacement include:

  • Restored oil circulation and pressure stability.
  • Prevention of leaks and oil starvation. 
  • Improved lubrication and temperature management.
  • Manufacturer-quality materials for long-lasting reliability.

All tanks in this range are built to meet or exceed original engineering standards, using high-grade alloys or reinforced composites to deliver durability, corrosion resistance, and a precise factory fit.
