Fleetguard Crankcase Ventilation Filter CV52001 for 6.7L Cummins Ram — Direct-Fit, Reduces Oil Mist

Fleetguard CV52001 is a replacement crankcase ventilation filter engineered to trap oil mist and contaminants from the engine crankcase, reducing emissions and protecting engine components.

This crankcase filter is designed for late-model 6.7L Cummins diesel engines found in 2007 and newer Ram 2500, 3500, 4500 and 5500 trucks. Built to meet the demands of heavy-duty use, it offers a direct-fit replacement for OE part numbers including CV52001, 4936636 and 68002433AB. The CV52001 helps control oil carryover, improves ventilation flow and is constructed to resist the high temperatures and contaminants typical of diesel operation.

How does the CV52001 reduce oil consumption and mess?

The filter captures oil mist and aerosolized droplets before they re-enter the intake or settle in the engine bay, which cuts down on oil loss and keeps surrounding components cleaner. That containment lowers the chance of oil dripping onto hot surfaces where it can burn or create residue buildup.

• High-efficiency media traps microscopic oil aerosols and vapors
• Seals and housing designed to prevent leaks under pressure
• Reduces oil weeping that can lead to buildup on turbochargers and exhaust components

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

The CV52001 is a direct-fit service replacement for many 6.7L Cummins installations used in Ram trucks from 2007 onward. It replaces multiple OE references so installation is straightforward on compatible models, though you should verify fit with your truck’s specific year and engine configuration before ordering.

• Compatible with 6.7L Cummins engines in 2007+ Ram 2500/3500/4500/5500
• Cross-references OE numbers CV52001, 4936636, 68002433AB
• Direct replacement—no modification required for matched models

How does it protect emissions control systems?

By filtering crankcase vapors, the CV52001 prevents oil and particulates from entering intake components and emission control devices. Cleaner crankcase emissions reduce the load on EGR, turbo, and DPF systems, helping those systems maintain designed performance and longevity.

• Removes particulates that could foul EGR and intake passages
• Minimizes oil droplets that can coat turbocharger vanes and sensors
• Supports stable crankcase ventilation to meet emission-control needs

What are the practical installation and maintenance tips?

Installing the CV52001 typically requires only basic hand tools and following vehicle service instructions for crankcase ventilation maintenance. Replace the unit according to manufacturer or service-interval guidance, and inspect seals and hoses for wear when servicing to ensure continued effectiveness.

• Follow vehicle manual for access and torque specifications
• Inspect surrounding hoses and grommets; replace if cracked or brittle
• Change filter at recommended intervals or if heavy contamination is visible

Who is this for: The Fleetguard CV52001 is intended for owners and mechanics of 6.7L Cummins-equipped Ram trucks (2007 and later) who need a reliable OEM-compatible crankcase ventilation filter. It’s suitable for fleet maintenance, towing and heavy-use vehicles where controlling oil carryover and protecting emission components is a priority. If you want a direct-fit, high-quality replacement that meets OE cross-reference numbers and helps maintain engine cleanliness, this filter is a practical service part to keep on hand.
