Blue smoke is of cause burning oil which could be one of many things

Pistons
Piston rings
Valve stem seals
Valve guides
Breather system
Turbo oil seals
Turbo oil drain blocked kinked
Engine overfilled with oil
Excessive oil pressure to turbo, pressure relief valve stuck
Headgasket blowning into an oilway

Depends when the engine smokes might give ya a clue
