If it smells like fuel thats a good place to start. I have the same issue and have replaced all my injectors and still have the smoking. So my next step is the fuel pressure regulator. White smoke is not always coolant. You can definitely have white smoke from overfueling, why do you think diesels smoke at start up before they reach operating temp? You can also have white smoke from it running lean as well. If the exhast smells like fuel why would you assume its coolant?? I have the exact same issue and have no coolant loss what so ever so before you speak know what your talking about. Talk to any diesel mechanic, hell even google white smoke and you will see. Black smoke is for partially burned fuel (not fully combusted). Unburned and partially burned fuel are two different things. If your not sure take a kerosene torpedo heater and you will see that it heavy white smoke when the fire goes out and the fuel is still flowing and it smells heavily of kerosene!!
