Fleetguard CV52001 Crankcase Filter – OCV for 6.7L Cummins (Ram 2007+ 2500/3500/4500/5500)

Fleetguard CV52001 Crankcase Filter delivers a dedicated Open Crankcase Ventilation (OCV) solution for 6.7L Cummins engines commonly found in Ram trucks built from 2007 onward. The open ventilation design helps the engine breathe properly and works with typical emission-control expectations, directing vented gases through the filtration path rather than into the surrounding engine bay.

Key benefits

• Open Crankcase Ventilation protects the engine and supports emission-control goals.
• May reduce oil mist, aerosol vapors, and oil drips in the engine bay, promoting a cleaner surrounding area.
• Designed for compatibility with most 6.7L Cummins engines in Ram 2007+ models.
• OE references CV52001, 4936636, 68002433AB enable straightforward replacement.

Fitment and daily use

• Fits most 6.7L Cummins engines on 2007+ Ram 2500, 3500, 4500, and 5500.
• Direct replacement option that aligns with the vehicle’s ventilation components and maintenance schedule.

In practice, drivers may notice a tidier engine bay and more predictable crankcase ventilation under heavy load or long highway drives. Results vary by vehicle age, condition, and operating environment, but this filter is designed to align with the listed OE numbers and engine configurations.

Quality and build

• Precision-engineered to fit standard mounting points and ducts in 6.7L Cummins installations.
• Constructed to handle crankcase vapors and engine heat while remaining durable across driving conditions.

Installation tips

• Ensure the old assembly is fully removed and mounting surfaces are clean for a proper seal.
• Consult the vehicle service manual for torque specs and gasket compatibility if in doubt.
