This oil pan gasket seals the interface between the engine block and the oil pan, preventing pressurized oil from leaking out of the crankcase. It sits in the groove machined into the pan rail and compresses evenly when the pan is torqued to specification. A degraded gasket allows oil to weep past the sealing surface, which can lead to low oil pressure and contamination of the engine exterior. This component is manufactured by AGCO to match the original groove geometry and crush profile, so it seats correctly without requiring additional sealant. On reinstallation, clean both mating surfaces thoroughly and torque the pan bolts in the sequence and to the value specified for the host engine.
