Sounds like crack in cylinder head exhaust port and coolant going out exhaust. When engine is cold the coolant burns and gives off the white smoke.Remove exhaust manifold and turbocharger. Plug turbo oil supply fitting. start engine and observe which cylinder exhaust port emits the white smoke. This will narrow the down the search area at least.

I had experience at cat 3406 E .same problem which was burning coolant.I found out it in waterpump where there is a hole that is provide signal if water pump is broken down via a signal hole.finally signa hole was plugged and the all water goes to engine over the pan goes to breather.
I overhaul water pump Changed coil. the problem finish.

My guess would be a nick in a head gasket or someone didn't torque down a head properly. A head leak doesn't always go both ways, so its not surprising that there is no coolant in the crankcase. Once the engine heats up, the small gap allowing the coolant to be introduced to the combustion chamber is eliminated as the hot parts expand. If a torque wrench is applied to the head bolts and the engine is warm, they will probably check good. They need to check those bolts when the engine is stone cold. I have even had a head with a small crack in it tighten up once it heats up. Start with the simple stuff and work your way up the cost food chain. Once those bolts are re-torqued I will bet your problem resolves. Good Luck.
