Hagen Brothers farms,Goodrich ND | If your sure it is excessive, more than normal airbox draining when cold and idling, which is mostly partially burned diesel fuel.
The most likely suspect is blower seals.
You can see leaking blower seals by running the engine with the blower intake box removed.
When running, you will see oil leaking in around the rotor shafts and radiating out across the blower end plates
You will need a good flashlight or trouble light to see the endplates clearly enough to see the oil streaks.
