6.7 Cummins Crankcase Vent Filter (CCV) | Fleetguard CV52001 | Fits 2007.5–2024 Ram 2500/3500/4500/5500 6.7L Cummins

Keep your 6.7L Cummins running strong and clean with the genuine Fleetguard CV52001 Crankcase Ventilation Filter. This high-efficiency Open Crankcase Ventilation (OCV) breather element is the factory-specified replacement for 2007.5–2024+ Ram trucks and other vehicles equipped with the Cummins 6.7L ISB or B6.7 diesel engine.

Mounted on top of the valve cover under the engine dress cover, the CV52001 separates and captures oil mist, aerosolized vapors, and contaminants from crankcase blow-by gases before they are routed back into the intake system. By preventing oil vapor from reaching the turbocharger compressor wheel and intercooler, it helps maintain peak performance, reduces oil consumption, minimizes engine bay oil drips, and supports emissions compliance.

Key Benefits & Features

• Superior Filtration — High-efficiency coalescing media captures harmful oil mist and particulates from crankcase gases.
• Turbo & Intake Protection — Prevents oil coating on the turbo compressor wheel and intercooler fins, reducing the risk of performance loss or costly repairs.
• Reduced Oil Consumption & Cleaner Engine Bay — Virtually eliminates oil drip and mist in the engine compartment.
• OEM-Quality Construction — Manufactured by Fleetguard (Cummins Filtration) to exact OEM specifications for perfect fit and reliable performance.
• Service Reminder Compatible — Triggers the factory “Perform Service” message on the overhead console/dash when replacement is due (codes P1507 / P1508 related to crankcase filter restriction).
• Easy Direct-Fit Replacement — Installs in the factory CCV housing with included O-ring seals.

Recommended Service Interval Factory interval is approximately 67,500 miles (or 75,000 miles on many 2019+ models), or when the “Perform Service” message appears. Because the breather tube routes gases toward the turbo inlet, many owners and shops prefer shorter intervals (every 30,000–50,000 miles) in severe service, towing, or high-idle applications to minimize oil vapor buildup on the turbo.
