Fleetguard Crankcase Filter CV52001 for 6.7L Cummins Ram Trucks — OCV element, reduces oil carryover

Fleetguard CV52001 is a replacement crankcase ventilation filter designed to trap oil mist and contaminants, protecting the engine and reducing oil carryover in 6.7L Cummins-equipped Ram trucks.

The Fleetguard CV52001 crankcase filter is an Open Crankcase Ventilation (OCV) element engineered to control crankcase emissions and limit oil vapor entering the engine compartment. Built to fit most 6.7L Cummins engines found in 2007-and-newer Ram 2500, 3500, 4500 and 5500 trucks, this filter matches OE references CV52001, 4936636 and 68002433AB. It helps maintain cleaner intake airflow and reduces oil consumption caused by mist and aerosolized oil.

How does this filter protect my engine?

The CV52001 captures oil droplets and particulate from blow-by gases before they re-enter the intake or escape into the engine bay. By removing mist and aerosols, it reduces deposits on intake components and lowers the chance of oil dripping onto hot surfaces.

• Engineered for Open Crankcase Ventilation systems to trap contaminants
• Reduces oil carryover that can foul intercoolers and intake plumbing
• Helps keep engine bay cleaner and reduces maintenance cleanup

Will this fit my Ram with a 6.7L Cummins engine?

The CV52001 is compatible with most 6.7L Cummins diesel applications in Ram 2500, 3500, 4500 and 5500 trucks from 2007 onward. Always cross-check vehicle fitment and OE numbers to confirm exact compatibility for your model year and configuration.

• Designed to replace OE CV52001, 4936636 and 68002433AB
• Fits most 6.7L Cummins engines in 2007+ Ram heavy-duty models
• Confirm vehicle year and engine code before purchase for best fit

How does this part reduce oil consumption and emissions?

By capturing oil mist, aerosols and small droplets within the ventilation stream, the filter prevents them from being burned in the intake or settling in the engine bay. That reduces both visible oil loss and the amount of hydrocarbons emitted from the crankcase ventilation.

• Traps aerosolized oil to limit oil loss through the ventilation system
• Helps reduce visible emissions related to crankcase blow-by
• Supports cleaner combustion by reducing oil introduced into intake air

What maintenance should I expect after installing CV52001?

Inspect and replace the crankcase filter according to your vehicle service schedule or when you notice increased oil in the ventilation lines. Regular replacement ensures the OCV system continues to remove contaminants effectively and minimizes oil-related issues in the intake and engine bay.

• Follow manufacturer or mechanic service intervals for OCV filter replacement
• Look for oil saturation or clogging as signs to change the element
• Replacing the filter can prevent secondary issues like intake deposits

Who is this for? The Fleetguard CV52001 is intended for owners, fleet managers and technicians who service 6.7L Cummins-equipped Ram 2500/3500/4500/5500 trucks and need a reliable OCV element that matches OE references. If you want to limit oil mist, maintain cleaner intake systems and match original equipment fitment and specifications, this replacement crankcase filter is built for routine maintenance and long-term engine care.
