Oil Tanks & Parts – Precision Lubrication Storage for Porsche Performance
The engine oil tank is a vital component in Porsche’s dry-sump lubrication system, designed to store and manage oil separately from the crankcase. Unlike traditional wet-sump setups, this system ensures consistent oil pressure, efficient cooling, and superior lubrication under all driving conditions — from spirited road use to high-performance track sessions.
At Design911, we offer a wide range of engine oil tanks, fittings, and associated components for Porsche models, both classic and modern. Built from high-grade aluminium, steel, and corrosion-resistant materials, our products are designed for durability, temperature stability, and optimal oil management.
Whether you’re maintaining an air-cooled 911 or servicing a contemporary GT model, our oil tanks and parts guarantee the reliability and performance your engine deserves.
What Do Oil Tanks & Components Do?
The oil tank serves as the reservoir in a dry-sump lubrication system, allowing continuous oil flow to the engine while preventing aeration or starvation during hard acceleration, braking, or cornering.
Core Functions:
- Stores
and circulates oil independently from the engine block.
- Maintains
stable oil pressure and temperature for consistent lubrication.
- Prevents
oil starvation during high-performance driving.
- Aids
in cooling, helping regulate operating temperatures.
- Separates air and oil, preventing foaming and pressure loss.
Supporting components — such as oil tank fittings, caps, hoses, and mounts — ensure secure flow, sealing, and performance integrity across the entire lubrication circuit.
Why Do Oil Tanks & Parts Fail?
Over time, exposure to heat, pressure, and vibration can cause the oil tank and its associated components to degrade or leak, compromising the lubrication system.
Common Causes of Failure Include:
- Corrosion
or internal contamination from moisture or sludge build-up.
- Cracks
or punctures caused by vibration or impact.
- Oil
leaks from damaged seals, caps, or connections.
- Blockages
in breather or feed lines affecting oil circulation.
- Heat stress, leading to material fatigue or deformation.
Typical symptoms include oil leaks, fluctuating oil pressure, overheating, or unusual engine noise — all signs that inspection or replacement is required.
Why Replace Oil Tank Components?
Replacing a worn or leaking oil tank ensures your Porsche’s lubrication system remains efficient and protected. Our precision-engineered oil tanks and accessories are designed to deliver superior durability, sealing, and performance under high stress.
Key Benefits:
- Restores stable oil pressure and circulation.
- Prevents leaks and contamination.
- Enhances oil cooling efficiency and consistency.
- Constructed from corrosion-resistant, heat-stable materials.
- Direct-fit
compatibility with a wide range of Porsche engines.
- Ideal for restorations, rebuilds, and performance applications.
A properly maintained oil tank system is essential for ensuring engine longevity and reliability — particularly in performance and motorsport use.
Highlights:
- Precision-engineered Porsche oil tanks and associated components.
- Designed for consistent oil pressure and temperature control.
- Durable materials for heat and corrosion resistance.
- Direct-fit solutions for 911, Cayman, Boxster, GT models and more.
- Perfect for rebuilds, restorations, and performance upgrades.
- Ensures optimal lubrication and engine reliability.
