ACDelco Engine Oil Pan Cover

ACDelco Engine Oil Pan Covers: OEM Precision for GM Engines

When it comes to protecting the bottom end of a GM engine, few components are as quietly critical as the engine oil pan cover. This cover — and its associated sealing gasket — forms the barrier between the oil pan and the engine block, keeping oil where it belongs and contaminants out. A failed or degraded oil pan cover can lead to leaks, oil starvation, and costly engine damage, making the quality of the replacement part every bit as important as the original.

ACDelco, the parts brand backed by General Motors, brings its OEM heritage directly to this category. ACDelco oil pan cover gaskets are offered under the GM Original Equipment (OE) line, meaning they are the same parts — or direct equivalents — to what was installed on your vehicle during factory assembly. GM Genuine Parts and ACDelco Original Equipment engine oil pan cover gaskets are designed, engineered, and tested to rigorous standards, and are the true OE parts installed during the production of or validated by General Motors for GM vehicles.

ACDelco GM Original Equipment Engine Oil Pan Gaskets are GM-recommended replacement components for engine mechanical systems, and this original equipment gasket delivers the same performance, durability, and service life as the factory original. For owners who demand nothing less than spec-correct repairs, that assurance is invaluable.

Broad Fitment Across GM's Most Popular Platforms

ACDelco's engine oil pan cover offerings are engineered for the engines that power some of GM's most iconic trucks, SUVs, and performance vehicles. Part number 12611384, for example, fits a wide range of vehicles including 1999–2019 Chevrolet Silverado and 2001–2014 Chevrolet Tahoe, and is compatible with various 8-cylinder engines ranging from 4.8L to 6.2L. Coverage also extends to models such as the GMC Sierra, Chevrolet Suburban, Cadillac Escalade, and Chevrolet Corvette. Additional part numbers — including 12623359 — are engineered specifically for Small Block Gen V (LT) applications across Cadillac, Chevrolet, and GMC platforms.

Why Choose ACDelco for This Repair?

Aftermarket oil pan cover gaskets vary widely in material quality and dimensional accuracy. Because the oil pan cover must seat perfectly against a machined engine block surface, even minor deviations in thickness or compliance can cause persistent seepage. ACDelco's OE-sourced gaskets eliminate that guesswork. These gaskets are designed to help seal the region between the oil pan cover and the engine block in order to help prevent oil leaks — a straightforward job done to factory tolerances.

ACDelco Gold parts are also available as high-quality alternatives to OE parts for those seeking a trusted option outside the strict OEM line. Across both tiers, the engineering pedigree traces back to General Motors, giving technicians and DIY enthusiasts confidence in the part before it ever goes on the vehicle.

Whether you're performing a routine engine reseal or addressing a fresh oil leak on a high-mileage work truck, ACDelco's engine oil pan cover components represent a direct, no-compromise path back to factory condition.
