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.
It is located between the cylinder head and the exhaust manifold; it prevents exhaust gases from escaping.
Cummins specifies the primary use for 10-liter L10 engines; aftermarket catalogs extend the application to the M11, ISM, and QSM families. Final compatibility should be verified using the engine’s serial number.
It is recommended for use in the lubricating oil cooler area of 11-liter Cummins M11 engines, particularly non-certified automotive versions. Normally, two engine gaskets are required when assembling the oil cooler.
The official Cummins website primarily lists it for the M11, but specialized catalogs also confirm compatibility with the L10, ISM, and QSM.
To ensure a successful purchase, it is still advisable to check the ESN and CPL, as the installation may vary depending on the engine configuration.
