The Crankcase Ventilation Filter 5263190 for Cummins Engines is a critical emissions and engine protection component designed to filter oil mist and contaminants from crankcase blow-by gases before they are released or recirculated. Engineered to OEM specifications, this filter helps maintain proper crankcase pressure, reduces oil consumption, and prevents oil vapor contamination of intake and aftertreatment systems.
Designed for Cummins B6.7, ISL9, QSL9, and QSB6.7 engines, this crankcase ventilation filter utilizes high-efficiency filtration media capable of capturing fine oil droplets while allowing clean gas flow. The durable housing and internal construction are built to withstand continuous operation, vibration, and harsh diesel engine environments.
A clogged or failed crankcase ventilation filter can lead to increased crankcase pressure, oil leaks, excessive oil consumption, turbo contamination, and emissions-related fault codes. Replacing it with this Cummins crankcase ventilation filter 5263190 restores proper ventilation performance, protects turbochargers and intake components, and supports emissions compliance.
This filter is ideal for routine maintenance, scheduled service intervals, fleet servicing, and preventative engine care across on-highway and off-highway Cummins-powered equipment.
