Cummins Breather Housing 5298061 for B6.7 ISB ISD6.7 ISBE QSB6.7

The Cummins Breather Housing (Part Number 5298061) is a critical crankcase ventilation component engineered for Cummins B6.7, ISB, ISD6.7, ISBE, ISBE4, and QSB6.7 diesel engines. This breather housing helps regulate internal crankcase pressure while separating oil mist from blow-by gases, ensuring clean airflow back into the intake or atmosphere depending on engine configuration.

Manufactured to OEM specifications, the 5298061 breather housing features a robust, heat-resistant construction designed to withstand continuous engine operation, vibration, and elevated temperatures. Proper crankcase ventilation is essential for maintaining engine efficiency, preventing oil leaks, and reducing emissions.

A worn or clogged breather housing can cause excessive crankcase pressure, oil leaks, increased oil consumption, and reduced engine performance. Replacing it with the Cummins 5298061 breather housing restores proper ventilation, protects seals and gaskets, and supports long-term engine reliability. This component is ideal for routine maintenance, engine repairs, and emissions-related service work.
