The only way you would get oil mixing would happen 2 ways. One being the turbo seals going out and leaking oil into the intake tract or two being excess oil in the intercooler entering the intake tract.

Pop off your intake pipe and see if its exceedingly oily. You could also remove the intercooler and see how much oil it has in it. A few tablespoons of oil is normal, a cup or more is not!

DPF filter and one injector is bad and then injectors gives more diesel then it should. And do the oil change fast or your main bearing are gone.
