It ensures the combustion chamber remains airtight and allows for the controlled flow of high-pressure, high-temperature exhaust gases toward the manifold and the turbocharger. The kit includes an exhaust valve and retaining cones.
Used on Cummins Heavy Duty and Medium Duty engines (industrial, marine, automotive, and construction applications) in the ISC (8.3L), ISL / ISL9 / ISLE4 (8.9L), QSC8.3, QSL9, 6C8.3, B4.5, and ISF3.8 engine series. Models from approximately 2002 to the present.
Always verify using the Engine Serial Number (ESN).
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.
It is installed between the engine block and the oil pan. It prevents lubricating oil from leaking out and dust or contaminants from entering the lower part of the engine.
For the L10 engine, the Mechanical, CELECT, and Gas versions are listed. Compatibility with other engines, such as the M11, ISM, and QSM, must be verified using the engine serial number (ESN), as different oil pans may be used.
