it might not be much help. but i was once told that if my cummins wasnt dirty. theres something wrong with it. lol. but as for the smoke issue. i have no idea, sorry, as for the oil. mine leaks also. idky, but i was told by a mechanic at my job that works on nothing but cummins that they all leak and hes not sure y but they do. and hes also the one that told me if it aint dirty theres somethin wrong with it. lol i hope i didnt completely waste ur time. but just throwin my 2 cents in there. hope all goes well.
