The WEHRLI CUSTOM FAB WCF100133 L5P DURAMAX HIGH-CAPACITY CAST ALUMINUM ENGINE OIL PAN is a premium collaboration between Wehrli Custom Fab and PPE designed to improve lubrication capacity, durability, and heat management for the 2017-2019 6.6L L5P Duramax platform.

Factory stamped steel oil pans can be susceptible to damage and provide limited oil capacity for hard-working diesel trucks. This high-capacity cast aluminum oil pan increases oil volume while offering significantly stronger construction. The heavy-duty cast design improves oil cooling and helps maintain stable lubrication during towing, racing, and high-load conditions.

Engineered specifically for the L5P Duramax platform, this oil pan integrates perfectly with the factory oil pickup system while maintaining proper clearances and OEM fitment. The added oil capacity helps support performance builds, extended towing sessions, and demanding work environments where consistent oil supply is critical.

FAQ

What advantage does a high-capacity oil pan provide?

A high-capacity oil pan increases the total amount of oil circulating through the engine. More oil helps stabilize temperatures, improve lubrication under load, and support demanding conditions like towing or performance tuning.

Is this oil pan stronger than the factory pan?

Yes. The WCFab/PPE oil pan uses thick cast aluminum construction which is significantly stronger and more impact resistant than the thin stamped factory steel pan.

Will this oil pan work with the factory oil pickup?

Yes. The oil pan is engineered to maintain compatibility with the factory oil pickup and internal oiling components for the 2017-2019 L5P Duramax engine.

Is tuning required after installing this oil pan?

No tuning is required. The oil pan is a mechanical upgrade designed to improve durability and oil capacity while maintaining OEM functionality.

Is this recommended for towing or heavy work trucks?

Absolutely. Increased oil capacity and improved heat management make this oil pan ideal for trucks used for towing, hauling, racing, or high-horsepower diesel builds.
