There are a lot of threads discussing your problem. Look toward the bottom of the page in "similar threads".

Change out the oils. Check the head gaskets. Check the turbo (if fitted).
Look for oil in water. (and water in oil). report back.
Also more details about your truck with pictures.

The oil in my crank case was due to my injectors being bad (wore out nozzles), weeping fuel into the cylinders then washing down to the crank case. The residual pressure in the post IP injector lines would drip fuel after shut down. Would also explain your smoke issue.

Other possible ways to get fuel in the crank case include the FDC, Flame intake heater, and the IP

I eliminated the FDC and flame heater also to be safe.

Do not run the engine anymore until you get the fuel in oil issue fixed. Fuel density compensator and hydraulic head o-rings are the most common causes of this.

If its hard to start and smoking, pull the injectors and have them pop-tested/rebuilt. Thats your first step. Then I'd have the gaskets(and O-rings) in the IP replaced. Finally, I'd delete the intake manifold heater and remove the FDC from the fuel loop.
