Intake Valve Seat - Rear
Detroit Diesel

The rear intake valve seat in the OM904 engine assembly is a specialized component designed to provide a reliable sealing surface for the intake valve at the rear position of the cylinder head. With an 8.10 mm height, 31 mm inner diameter, and 40.37 mm outer diameter, it ensures a tight fit that maintains compression integrity. This seat ring plays a crucial role in optimizing airflow into the combustion chamber, directly affecting engine power and efficiency. Constructed from materials capable of withstanding high temperatures and thermal cycling, it resists deformation and wear over extended periods of operation. Proper installation of this seat ring guarantees consistent sealing and prevents leakage, which is vital for maintaining engine performance and emissions standards.
