What is the CCV Filter Change Interval for Ram 6.7 Cummins?

The Chrysler factory suggested change interval for the Cummins 6.7L Crank Case Vent Filter is 67,500 miles or when the message appears. Owners of the Cummins 6.7L now know that changing the Cummins Crankcase Vent Filter CV52001 at a shorter service interval is money well spent.

KLM Performance recommends you purchase the 6.7L Cummins 3999820 Crankcase Breather Gasket when you order this crankcase ventilation filter for your 6.7L Cummins diesel.

This Fleetguard CV52001 - CUMMINS: OCV / Crankcase Ventilation Kit /  Breather Assembly is the one used on the Cummins ISB Engines. Because the Cummins 6.7L Crankcase Vent Filter breather tube is location is next to the turbo inlet, we recommend shorter change intervals. A quicker change interval of the FLEETGUARD Crank Case Vent Filter CV52001 will help minimize oil vapor coating the turbo compressor wheel, air inlet passageways, and intercooler.

Chrysler recommends the Dodge Ram trucks with the 6.7L Cummins Crankcase Ventilation Filter replacement interval when a message is displayed on your overhead console alerts you that the Crankcase Vent Filter is now clogged.

In the 2007.5 model, Cummins 6.7L diesel contains a new emissions system which no longer vents crankcase gasses into the atmosphere. With the new 6.7L Cummins emissions systems, they've switched to a CCV or Closed Crankcase Ventilation system. This new CCV system contains a Fleetguard 6.7L Cummins Crank Case Vent Filter CV52001. The Cummins 6.7L diesel employs a Closed Crankcase Ventilation system. This Closed Crankcase Ventilation system collects these crankcase gasses. These oily gasses from the crankcase then enter into your turbocharger inlet air stream post air filter. This Closed Crankcase Ventilation system will allow a greasy build-up on the turbo compressor wheel if the filter is not serviced. If the FLEETGUARD 6.7L Cummins Crankcase Breather Filter CV52001 breather filter becomes plugged crankcase blow-by is higher than average; these gasses can now coat the inside of the intercooler which lowers its efficiency. By changing the Cummins 6.7L Turbo Diesel Crank Case Vent Filter at regular preventive maintenance intervals, you will save time, money and a lot of aggravation. Crankcase Ventilation Filter CV52001 / Cummins 4936636 High-efficiency crankcase aerosol filtration Reduces oil consumption and environmental waste on the Dodge Ram trucks and other vehicles that use the Cummins 6.7L diesel engines.

When the Preform Service message is illuminated on the overhead display you will need to immediately replace the crankcase ventilation filter. A delay in replacing this vital filter will cause the following Diagnostic Trouble Codes / DCT codes to appear.

  • P1507 crankcase filter restriction.
  • P1508 crankcase filter restriction means the restriction has triggered a second warning to replace this engine filter.
