The 2007.5 and newer Dodge Ram trucks powered by the Cummins 6.7L turbo diesel engine now has a crankcase vent filter installed as a part of the emissions control system. This CCV filter or Breather Element location is on the top of the motor under the dress cover.
Chrysler mandates a change interval for the CCV breather element of 67,500 miles or at the time when the overhead message appears. We very strongly recommend a shorter change interval of 45,000 to 50,000 miles. Shorter change interval of this breather element is because the CCV breather tube routing goes to the turbo inlet. KLM Performance recommends this shorter change interval to help minimize oil vapor from coating the turbo compressor wheel. Owners of the Dodge Cummins 6.7L now know that changing this Mopar Crank Case Vent Filter in your Dodge Ram 6.7L Cummins engine at a lower service interval is money well spent.
Do not ignore the message being displayed on the overhead console! This message is letting you know the Crankcase Vent Filter is now full and must be changed immediately.
