CCV Filters: Control Crankcase Ventilation
The Closed Crankcase Ventilation (CCV) system routes crankcase gases back into the intake to reduce emissions. Over time, the CCV filter becomes saturated with oil, leading to increased oil consumption, intake fouling, and turbo compressor contamination. iFJF Direct carries OEM-spec CCV filter replacements.
CCV Filter Applications
- GM Duramax 6.6L (LML, L5P): Factory CCV filter replacement. Clogged filters cause excessive crankcase pressure and oil leaks.
- Ram Cummins 6.7L (2007.5+): CCV filter element replacement for the factory crankcase ventilation housing.
FAQ
Q: What are the symptoms of a clogged CCV filter?
A: Oil leaking from seals and gaskets (due to excessive crankcase pressure), increased oil consumption, oil in the intercooler piping, and turbo compressor wheel oil coating. Replace the CCV filter every 60,000 miles or when you notice these symptoms.
