I'm not much of an Diesel Mechanic but with the little information provided, I believe you are experiencing oil mixing in with your gas when it combust. this is caused by 1 of two things, if it is an older truck, your piston rings might be going out and letting oil seep into you combustion chamber and burning when the gas burns (cost more money to fix), or it could be that your "drain" back holes in the engine is clogged and oil is seeping into the valves thus in turns seep into the combustion chamber and you just need to clean it. you can do this by removing the valve cover and cleaning those holes.
worn piston rings or valve stems

What causes Blue smoke from diesel engine?
Blue smoke in both petrol and diesel engines is caused by the burning of engine oil during the combustion phase, i.e there is oil in the combustion chamber. The oil could be entering the combustion chamber via the valve stem seals or the oil rings. Also check that the oil level is correct as too much oil can cause blue smoke Also check that there are no oil leaks that are allowing oil to enter the exhaust system. If all that is in working order, I suggest you pull out the engine and get it overhauled.Read more: What_causes_black_smoke_or_blue_smoke_in_gas_engines
