Is there oil in your coolant or coolant in your oil?
Pull the charge pipe off the turbo see if there is excessive oil in there.

Pull your intake and look at the turbo. Is their a ton of oil in the intake? How dies the turbo look?

If it truly us oil, I would guess either the CDR went bad, or the turbo did.

Are you sure it was oil? Sometimes when you start a diesel these black watery spots come out, but that's just because the moisture in the exhaust combines with the soot. It's actually kinda common. Is that what is happening?

Just wondering. My factory exhaust did it, cold
morning starts would leave a trail on the concrete from yhe exhaust. Worried me in the beggining, but that's normal.

Does it knock at idle?

If so, take a wrench and loosen each injector line. Do it one at a time, if the knock goes away when you loosen a line, that could mean a bad injector. I'm hoping thats what it is.

If not, pull the valve covers and look at the valvetrain, anything out of the ordinary?
