I have a f-350 ford truck with the 6.0 diesel. It has begun to put out light blue smoke when I first start it. It quits after a few minutes. I am also having some fluid leakage out of the muffler when I turn the engine off. I resembles oil, but is very thin like water. Truck is running fine.

Swap out the crank and cam sensors

White smoke is a sign of water which may be a sign of a blown head gasket..... havve a reputable shop do a compression test on this vehicle.
If the car runs a few minutes does it overheat??? If so turn it off and dont drive it until it gets fixed if not white could be condensation and low batteries could be just in need of replacement and or a good charge.

Black smoke from a diesel is caused by overfueling, even with a banks the engine obviously is burning the fuel efficiently. Black smoke will not make your truck produce more power, i am not sure why you would want this to happen anyway.

well the question is where did the coolant go. if it didnt leak out it must have went out the pipe. As you stated, white smoke, white smoke is coolant. You definately need to get this to the shop. You cannot drive it this way or further damage will occur.

Thats a guessing game, but first, if the battery light was on, that means no alternator output. So recharge the batteries and be sure they are good, Then replace the alternator. If the batteries and the alt are good, and the battery light is off, then all should be OK.

THER ARE THREE COLORS OF SMOKE. WHITE IS WATER, BLUE BURNING OIL, BLACK RUNNING RICH.CHECK COOLANT LEVEL AND DO A BLOCK TEST. HOPE THIS WILL HELP YOU SOLVE YOUR PROBLEM.

my ford ranger run rought when i rare it up it blows some black smoke

Blue smoke is oil, probably a sign of worn rings, has it done quite high mileage?

If you Cleaned up all of the Diesel There is still a Small amount of Oil from the Diesel on Anything that it Touched. Use some Spray DeGreaser on a Shop Wrag and let it dry Before you restart. Should be OK.

BLACK SMOKE INDICATES RUNNING RICH.
