When you see a classic GM truck, you assume it has either the original carbureted engine or maybe even a LS or LT swap in it. Those three staple engines are what the norm has become.

Imagine draining the oil from your Duramax truck, only to discover that nearly a quart of dirty oil remains trapped inside. That's exactly what Banks engineers uncovered using a custom-made see-through replica of the stock oil pan. This innovative test revealed a critical flaw in the Duramax 6.6-liter engine's stock oil pan design, and the results are as eye-opening as they are concerning.

As we speed toward the 25th anniversary of the Duramax diesel engine, let us take a moment to reflect on the astonishing history of this pivotal heavy-duty engine. The story begins in 1996 as General Motors was finalizing plans for its next-generation of light- and heavy-duty pickups. The company knew it needed a new, modern diesel engine in order to compete with the likes of Dodge's 5.9-liter Cummins and Ford's 7.3-liter Power Stroke.
