Be careful of white smoke as it will irritate your eyes and skin. Blowing white smoke is a red flag for your diesel engine , yet we see this happen all the time to our customers. In many cases, white smoke emanating from the tailpipe (often at idle once the engine reached operating temperature) typically means a worn out injector. To be more specific, the white smoke you see is your diesel fuel , unburne or only partially burned. They range from faulty fuel injectors to retarded fuel injectio n timing, or even low compression.

If your car has a diesel engine , then the white smoke might be indicating that there is a problem with the fuel pump injection. When the fuel pump injection timing is off, it is difficult to determine the root cause. There are two main reasons, the first might be dirty or low quality fuel (something which can be problematic with diesel engines ). If the problem is one or more dirty or malfunctioning glow plugs, then the smoke will usually go away after the engine heats up and begins to sustain its own combustion without them. On the common rail Cummins, white smoke is more characteristic of an injector problem. If the exhaust smells almost like bug spray , it is.

Diesel Smoke tells YOU a Story. Basically, smoke from a diesel engine indicates that something is not right. In order to function properly, a diesel engine needs precise timing of the injector pump and high pressure. So, any decrease in the pressure or delay in the fuel delivery to the combustion chamber will result in incomplete combustion, leading to white smoke.

But mostly, it is the incorrect injector timing in the cylinders. It is normal to see white smoke from the exhaust during sub-zero and colder weather, at least until the engine warms up. Old diesels will smoke white on start up and clear up as they warm up and get some compression. This causes white smoke. That indicates either a blown head gasket, intake gasket, turbo seal, or cracked head or block.

White smoke during start up can be due to the following causes:. It takes some time for the engine system to develop enough revolutions (RPM) and power to burn the fuel. It should be taken as an indication that there is a problem existing (or developing), that will potentially shorten the engine life, or result in unnecessary costs.
