White smoke from the exhaust pipe - what kind of engine malfunctions can it portend?

White smoke from the tailpipe can be a cause for concern, but it doesn't have to be. What color smoke can come from the exhaust system? Basically it could be:

● black;

● blue;

● white.

Each of them can mean different malfunctions or be a sign of engine hardware failure. For example, blue smoke in gasoline and diesel engines is most often a sign of engine oil burnout. In addition, the back of the car stinks mercilessly, which is not very pleasant. Black smoke is characteristic of the vast majority of diesel engines and indicates a large amount of unburned fuel (too much fuel), leaking injectors (poor atomization), or a cut catalytic converter. What does white smoke from the exhaust mean? Is that also cause for concern?

White smoke from the chimney - what are the reasons? What malfunctions can this mean?

The first thing to definitely mention at the very beginning is that white smoke from the exhaust pipe when firing does not necessarily mean a malfunction. Why? It can simply be confused with colorless water vapour. This phenomenon sometimes occurs on very humid days when you start the engine after an overnight stay "under the cloud". Moisture, which also collects in the exhaust pipe, heats up very quickly and turns into water vapour. This is especially evident when white smoke comes out of the gas system exhaust. HBO is inaccurately adjusted and increases the temperature of the exhaust gases, and this contributes to the formation of water vapor in large quantities.

White smelly smoke from the exhaust pipe - is it something other than a gasket?

Yes, of course. Not every case means that the engine is waiting for an overhaul when white smoke comes out of the exhaust pipe. A diesel or gasoline engine can simply draw water into the combustion chamber. However, it may happen that it does not come from the water channels, but from the exhaust gas recirculation (EGR) valve. How is this possible? In order not to force hot exhaust gases into the combustion chamber, they are cooled in a water cooler (special). If it is damaged, water will enter the cylinders and white smoke from the diesel exhaust will be emitted in its vaporized form.

When does white smoke from the exhaust indicate a damaged cylinder head gasket?

To be sure of this, you need to exclude the presence and damage of the EGR cooler. In addition, you should check the condition of the cooling system hoses (whether they are swollen and at what temperature) and test for CO2 content in the cooling system and coolant. If, in addition, you can hear the gurgling of liquid (obviously gas) in the expansion tank, and the diesel dipstick is pushed out of its place, then the cylinder head gasket will almost certainly need to be replaced. White smoke from the exhaust pipe, seen with the naked eye, in this case means an upcoming engine overhaul.

White smoke from the HBO pipe and diagnostics of cars with diesel and gasoline engines

Remember that white smoke from the tailpipe "petrol" and "diesel is not to be underestimated. Even if it's just steam, but there is HBO in the car, okay, see if anything needs to be adjusted. In addition, driving a car that constantly smokes white or any other color is an easy route to a powertrain overhaul., or its accessories.

What does white smoke from the exhaust pipe mean and how to get rid of it?

In fact, the worst thing that can happen to your car when you notice puffs of smoke is a running engine. If you don't know what it looks like, take a look at one of the popular film portals. The good news is that this happens almost exclusively in turbocharged diesels. If you notice white smoke on a cold diesel engine that does not go away over time, perform an additional check on the CO2 level in the coolant. Also make an appointment for a head gasket replacement to rule out a leak problem. What costs need to be considered?

White smoke from the exhaust pipe and the cost of repairing the engine at the mechanic

If you just look at the prices for cylinder head gaskets, you can be happy - they are usually just over 10 euros. However, there is also a head layout, new pivots (do not persuade to assemble the engine on old pivots!), A new timing drive. It may be necessary to replace the valve stem seals, since the head has already been removed, and of course there is work to be done. Effect? You will pay more than 100 euros, so be prepared for the white smoke effects from the tailpipe to hit your pocket.

What's the last piece of advice you can take to heart? If You Notice White Smoke When Starting Gasoline or Diesel - Don't Panic. It could be water vapor. Not all smoke is a bad cylinder head gasket. First, diagnose, and then do a major overhaul.
