Seal the component joint to prevent oil or engine fluids from leaking. Cummins primarily uses it for 11-liter M11 engines, but it is also installed in L10, ISM, and QSM engines.
To confirm the exact application, you should check the motor’s ESN/CPL, as it may vary depending on the configuration.
Cylinder head; can be used as a seat for the intake or exhaust valve, depending on the cylinder head configuration.
Compatible engines: Cummins L10 / LTA10. Some aftermarket catalogs also list the M11, but Cummins officially specifies part number 3418040 primarily for non-certified 10-liter L10 engines. Always verify using the Engine Serial Number (ESN).
The oil pan gasket seals the joint between the engine block and the oil pan; this is the narrow “early/narrow pan” version, typically with 34 holes.
Primary application for mechanical, non-certified L10 motors with a narrow housing. Some aftermarket catalogs also list it for certain M11 and ISM configurations, but it is not universal for all of these motors.
You must verify the housing type and the motor’s serial number before purchase.
