Oil Pan Gasket
Detroit Diesel

Pan seal is engineered to provide a leak-tight interface between the engine block and its sump, resisting oil pressures and thermal cycling that occur in heavy-duty service. The profile measures 386.90 mm in width and 1166.80 mm in length, ensuring a precise fit with the corresponding flange geometry used on compatible Detroit Diesel configurations. Constructed from rubber, this material balances elasticity with durability to maintain consistent compression under vibration and temperature swings. VMRS code 045-013-003 identifies it as the lubrication subsystem seal for the pan assembly, aligning maintenance practices with standard diagnostic procedures. In operation, the joint seal prevents oil seepage at the critical interface, protecting the crankcase environment, maintaining proper oil levels for lubrication, and supporting cooling and filtration circuits. Proper installation requires clean, flat mating surfaces and even seating to avoid distortion or premature failure. This component plays a pivotal role in the reliability of the lubrication system in on-road and off-road applications, contributing to reduced oil loss, cleaner engine bays, and extended service life for components in contact with the sump.
