Detailed Description

This Dorman engine oil pan is designed as a precision-engineered replacement for select Cadillac, Buick, Pontiac, and Oldsmobile applications. It is a direct replacement for vehicles such as the Cadillac DeVille, Cadillac Seville, Cadillac Eldorado, Cadillac Allante, Cadillac DTS, Buick Lucerne, Pontiac Bonneville, and Oldsmobile Aurora, helping restore proper crankcase oil containment after a damaged or leaking pan is removed. This part cross-references ATP 103384 for the same application.

Built from aluminum, Dorman 264-127 uses a baffled internal design and a wet-sump layout to match the original equipment style on the listed applications. The pan includes a drain plug and does not include a gasket or seal, pickup tube, or installation hardware. It is intended for engines that use a 5-quart oil pan configuration with a 12 mm drain thread size.

Common Problems This Part Can Help Solve

• Engine oil leaks from a cracked, rusted, or damaged oil pan
• Oil seepage around the drain plug area
• Loss of proper oil containment after impact damage
• Service issues caused by a warped or corroded pan flange
• Noise or oil movement concerns related to a worn internal baffle

Installation Notes and Tips

Verify engine application, mounting hole count, and drain thread size before installation. Clean the sealing surface thoroughly and replace the gasket or seal separately, since it is not included. Inspect the drain plug and mating surfaces during service, and confirm the pan clears surrounding components on the vehicle.
