Description

The MAHLE OS32172 engine oil pan gasket is a direct-fit replacement designed to stop leaks and maintain a clean engine. Built to OE form, fit, and function, it restores a reliable seal at the pan rails.

This gasket is specifically listed for 1989–1998 Cummins 3.9L 4BT (B-Series / 4B) applications, commonly found in work trucks, industrial 4B/4BT swaps, and daily drivers. Before installation, clean both sealing surfaces thoroughly and check pan flange straightness. Follow Cummins torque specs and pattern, applying RTV at corners where specified by the service manual.
