The WEHRLI CUSTOM FAB WCF100134 L5P DURAMAX HIGH-CAPACITY CAST ALUMINUM ENGINE OIL PAN is a heavy-duty oil system upgrade engineered through a collaboration between Wehrli Custom Fabrication and PPE. Designed specifically for the 2020-2024 6.6L L5P Duramax, this cast aluminum oil pan increases oil capacity while improving heat dissipation and overall engine lubrication stability.

High-performance diesel trucks often operate under extreme loads, towing demands, and elevated temperatures. The WCF100134 oil pan addresses these conditions with a high-capacity cast aluminum design that increases oil volume and improves cooling efficiency compared to the restrictive factory stamped steel pan. The increased oil capacity helps maintain more consistent oil temperatures and provides improved lubrication during heavy-duty use.

Constructed from precision cast aluminum, the oil pan delivers exceptional durability and rigidity while incorporating integrated cooling fins to help reduce oil temperatures. The deeper sump design increases total oil volume, providing improved lubrication for engines producing higher horsepower or operating in severe-duty environments.

FAQ

How much additional oil capacity does this pan provide?

The WCF100134 increases engine oil capacity compared to the factory pan, helping improve lubrication stability and oil temperature management during heavy-duty operation.

Why upgrade to a high-capacity oil pan?

Increased oil volume allows the engine oil to absorb more heat and maintain stable lubrication under high load conditions such as towing, racing, or heavy performance builds.

Is this oil pan compatible with stock trucks?

Yes. The oil pan is engineered specifically for the 2020-2024 L5P Duramax platform and can be installed on both stock and modified trucks.

What are the benefits of cast aluminum construction?

Cast aluminum provides superior strength, improved heat dissipation, and greater durability compared to factory stamped steel oil pans.

Is professional installation recommended?

Because installation requires removal of the factory oil pan and resealing the engine oil system, professional installation or experienced mechanical knowledge is recommended.
