Customer: replied 6 years ago.
no oil hasnt been overfilled,ive had this truck about 4 years and first time ever noticed it.i do a lot of idling
Expert:  DR.Cummins replied 6 years ago.
Well the oil that you are seeing is a result of high crank case pressure, you should have a blow by test done (crank case pressure test) causes of excessive blow by are

Crankcase ventilation system is plugged,Turbocharger, air compressor, head valve guides worn, or worst case Piston, piston rings, or cylinder liner is worn or damaged, you would have to get blow by checked during the checks, they will isolate the turbo and compressor, to find out if there the cause, hope this helps
