We supply high-quality replacement oil tank hardware crafted to the same dimensional standards as the original Porsche components. Manufactured from durable, corrosion-resistant materials, these washers are designed to withstand continuous exposure to oil, heat, and pressure—making them ideal for classic Porsche maintenance and restorations.
What Does the Oil Tank Mounting Kit Do?
Each component in this kit works together to secure the oil tank and maintain stable dry-sump operation.
Core Functions:
- Provides secure mounting and vibration resistance for the oil tank.
- Ensures even load distribution across mounting points.
- Maintains tank alignment for correct oil line routing.
- Prevents leaks by keeping the tank firmly compressed against mounting surfaces.
- Supports lubrication stability during high-performance driving.
These hardware components are crucial for maintaining the stability and efficiency of Porsche’s iconic dry-sump system.
Why Do Oil Tank Mounting Components Fail?
Over decades of use—especially in classic Porsches—mounting hardware faces extreme conditions including heat, vibration, oil exposure, and corrosion.
Common Causes of Failure Include:
- Corrosion from moisture, road debris, and oil residue.
- Thermal cycling, weakening metal components over time.
- Vibration fatigue, causing washers or nuts to deform.
- Aged threads leading to poor clamping force.
- Loss of tension from worn or compressed washers.
When mounting components weaken or degrade, the oil tank can shift, vibrate, or leak—posing risks to lubrication pressure, engine longevity, and overall performance.
Why Replace or Upgrade Your Porsche Oil Tank Mounting Kit?
Restoring your oil tank hardware ensures safe, leak-free operation and preserves the integrity of Porsche’s dry-sump lubrication system.
