Distinguish 6.7 Cummins Crankcase Filter Problems
We made a table so that it would be easy to understand the major and minor problems with their specific reasons. After meaningful research, we collect this information and try to present it in front of you.
| 6.7 Cummins Problems | Reasons |
| Clogged CCV | Dirt build-up |
| Sensor issue | Sensor is damaged |
| Idling Long & improper emission | Not getting enough oil flow |
| Leak in exhaust | Faulty CCV, clogged vent |
After seeing the comparison table, we get an overview of the 6 7 Cummins CCV filter problems. To know the issues in detail and distinguish the reasons, we describe them with a proper solution that will help you recover from these problems quickly.
Clogged CCV
One of the leading problems is the clogged crankcase filter, which significantly impacts the entire function of the Crankcase filter.
After a long time of riding without maintaining proper oil change can lead to dirt and carbon build-up in the crankcase valve line. And this clogs the oil flow. And it can throw a code like p1507 or P1506.
In this case, you need to either clean the crankcase filter or replace it if cleaning does not seem to be that effective.
Crankcase Sensor Issue
Another fundamental problem is the sensor is faulty. The fuel won’t pass thoroughly into the combustion chamber when the crankcase filter valve sensor becomes damaged. As a result, it won’t show the proper performance mileage that it should have.
In that case, you should replace the sensor. And don’t fall for the trap of injection cleaning, as most local garages can try to fill their pockets.
Idling Long & Improper Emission
Another most seen problem with the 6.7 Cummins crankcase filter is reduced fuel economy. And engine idling long. Well, when the crankcase filter recalls, and still you don’t replace it, it won’t provide the performance peak that your Cummins engine usually gives.
So, replacing the crankcase filter every 67K miles is always recommended.
Leak in Exhaust
Exhaust leaking is another issue you can face when you have a fault crankcase filter. Again, sometimes, if the crankcase filter valve is clogged, it can create a blockage to the injection and result in exhaust leaks.
Here, we will also go for the same suggestion: to give proper attention to the crankcase filter recall.
