PPE Heavy-Duty Deep Cast Aluminum Engine Oil Pan 2020-2026 LM2/LZ0 Duramax

This new deep pan is cast from high-quality A356.0-T6 heat-treated aluminum alloy using permanent steel molds and holds an additional two quarts of oil. More fluid increases thermal stamina which helps promote longer service life. We’ve added machined grooves to the outer surface of the pan to increase the effective surface area and maximize thermal performance.

The factory drain plug port is located above the bottom of the pan and about half a quart of dirty oil remains which immediately contaminates your fresh oil with sludge and ferrous metal. PPE solves that filthy problem with a flat, angled bottom, and a drain plug port engineered below the bottom surface of the pan to ensure a complete drain.

A 1/8-inch NPT port is tapped and plugged into the side if you want to run an optional temperature sensor. We've also included a high-power Neodymium magnet equipped, billet, hardened stainless steel drain plug, This powerful plug pulls ferrous particles out of your oil before they damage your internals.

Features:
- Premium A356.0-T6 heat-treated cast aluminum alloy – a high-strength, thermally conductive material
- Precision-cast using permanent steel molds for a smooth, consistent finish and high dimensional accuracy
- Increases oil capacity by 2 quarts for higher thermal capacity
- Longitudinal cooling channels along the bottom of the pan, increasing external surface area and enhancing heat dissipation
- Cast-in gussets for additional upper oil pan flange support and increased rigidity
- Precision machined sealant grooves guide the application of RTV-style sealant for a consistent bead and a reliable seal
- Stainless steel drain plug with built-in high temperature rated neodymium magnet

GM 3.0L Duramax Engine Oil Pan

In our testing on the LM2, we observed an increase in oil capacity from 7 quarts with the OE GM oil pan (GM #55506665) and filter to 9 1/2 quarts with the PPE Heavy-Duty Deep Oil Pan and PPE Premium Oil Filter 114000650.

Recommendation Disclaimer
If using a copper washer SKU 114052002 on the drain plug, replace it with a new washer during each service.
If using a compound washer SKU 114052004, inspect the washer during each service and replace as needed.

About the factory oil pan

The factory oil pan (GM #55506665) shown in last picture was removed from a new truck with 1,000 miles on the odometer. Despite the low mileage, approximately half a quart of contaminated oil and sludge was found remaining in the pan. The factory style drain plug does not allow for full oil drainage and the factory filter cannot effectively remove all the contaminants from the engine oil. The PPE oil pan and oil filter offers a solution to this common issue and provides superior engine protection.
