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.
