Why does my diesel engine have white smoke?

Some other causes for a diesel motor failing to burn the actual diesel fuel and generating white smoke include badly sealed piston rings, burnt-out glow plugs, poor energy quality or a clogged air conditioner filter. Extreme engine problems, like a cracked block, a damaged cylinder head, leaking valves or a blown head gasket, can also cause the problem.
Occasionally white smoke only seems when the engine starts chilly, going away as the powerplant warms up. When this particular occurs, it is typically because of deposits around the piston bands. Products designed to flush co2 away from the pistons frequently cures this problem. If the white-colored smoke is due to the serp being too cool, including an automatic pre-heater may get rid of white diesel smoke.
Diesel powered engines also sometimes generate black or blue smoke cigarettes, both of which are also indications of problems within the engine. Dark smoke indicates poor ignition of the diesel fuel, as well as blue smoke is a indication of oil burning inside the engine.
