Kubota CCV Filter Maintenance

As Part of EPA Tier 4 regulations, all Kubota Common Rail (CR) engines are equipped with a Crankcase Ventilation (CCV) system.

We have experienced some instances of the CCV filter becoming clogged prior to the 1500 hour Kubota recommended replacement interval. Clogging of this filter may result in oil buildup in this housing failing to drain back to crankcase.  This can lead to oil being introduced to the intake tract. Possible issues include misdiagnosis of turbo failure, emissions related codes, frequent DPF regeneration, and potential for engine to continue to run with key off.
