You should be only using full-synthetic HDDO in your PSD. If you don't, it won't be long until you'll experience expensive turbo repair bills. It's a must. Some suggestions are provided in the link below:

The engine and oil will stay cooler and your smoke problem should improve markedly.

Here's a link on diesel smoke:

I have water drops coming out the exhaust which is producing lots of clear smoke. I'm using (Gal per week) anti-freeze and none is going into the engine oil. Truck runs great other wise. Any ideas??

tamrak, they may be two unrelated problems. White smoke is a sign of water vapor or fuel that has been atomized, but not burned. Water vapor may be present in the fuel, or water may be leaking into the cylinders from the cooling system. Also, air in the fuel can cause white smoke. White smoke usually occurs when there is not enough heat to burn the fuel. The unburned fuel particles go out the tailpipe and typically produce a rich fuel smell. It's not unusual to see white smoke in the exhaust, during cold weather, until the engine warms up. Bad glow plugs (burned out, coated with carbon, or not receiving proper start-up voltage) or a faulty glow plug control module can cause white smoke on engine start up. Low engine cranking speed may also produce white smoke. If white smoke is visible after the engine has warmed up, the engine may have one or more bad injectors, retarded injection timing, or worn injection pump. Low compression can also be a source of white smoke.
