Porsche Oil Tank Mounting Washer - Precision Mounting Component for 911 (1965–1989) & 914-6
Sold each - 2 required per car
The oil tank mounting washer is a small
yet vital part of the Porsche dry-sump lubrication system, designed to
secure the oil tank in position and maintain proper sealing under vibration and
temperature variations. This precision-engineered washer ensures that the oil
tank remains stable, preventing movement or leaks that can affect oil flow and
engine performance.

We supply high-quality replacement oil tank mounting washers 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 Washer Do?
The oil tank mounting washer plays a crucial role in your Porsche’s lubrication and engine stability system.
Core Functions:
- Secures the oil tank to the chassis mounting points.
- Distributes load evenly across the mounting area.
- Prevents vibration and movement during operation.
- Ensures proper sealing against leaks or oil seepage.
- Maintains correct alignment for oil line connections.
Without a properly functioning washer, the oil tank can shift slightly, leading to unwanted vibrations, stress on oil fittings, or even oil leaks that compromise system pressure.
Why Do Oil Tank Mounting Washers Fail?
Despite their small size, mounting washers endure extreme conditions—heat, vibration, and oil exposure. Over time, this can lead to wear and failure.
Common Causes of Failure Include:
- Thermal
fatigue from repeated heat cycles.
- Corrosion
caused by prolonged contact with oil and moisture.
- Metal
fatigue from vibration or overtightening.
- Deformation
or cracking due to age or mechanical stress.
- Loss of elasticity or tension affecting mounting stability.
When a washer becomes worn or corroded, it can no longer secure the tank properly—potentially leading to oil leaks, vibration noise, or tank misalignment.
Why Replace or Upgrade Your Oil Tank Mounting Washer?
Replacing a worn or damaged oil tank mounting washer restores secure fitment and ensures the integrity of your oil system. This simple yet essential component helps prevent larger mechanical issues and supports consistent lubrication performance.
Key Benefits:
- Restores proper oil tank stability and alignment.
- Prevents vibration, leaks, or stress on mounting bolts.
- Maintains efficient oil system pressure and performance.
- Manufactured to precise Porsche specifications for accurate fit.
- Constructed from high-grade, oil- and heat-resistant material.
- Ideal for Porsche 911 (1965–1989) and 914-6 restoration or maintenance.
