Occasional white smoke from exhaust

Occasional white smoke from exhaust, Diagnosis? Im not sure where to start with this one. The car was recently purchased from an old lady whom didnt dri.


White smoke from exhaust that looks like thin wisp is the topic for today. And not as scary as it looks, white smoke should not be a matter of concern. The accumulated condensation is simply finding a way out of the pipe.


If smoke is being release then this is indicative of a problem. HOWTO looks at all the possible reasons why white smoke is coming from your exhaust pipe. Some white exhaust smoke is normal, especially when you first start the car. Condensation can turn to vapor, providing what looks like white exhaust.


But excessive white smoke likely means coolant is leaking into the engine combustion chambers. In very cold temperatures, the heated exhaust can freeze into minute fuel droplets when exiting the exhaust and produce a more prolonged emission of white smoke for a very short period of driving time. I concur with the head gasket, having had one blow before.


The black smoke may show there is a return fuel line which is obstructed. Fuel injectors and sensors might also be damaged. A final problem which can be diagnosed from black smoke is problem with the air filter. This is generally steam caused by condensation. As the engine warms up and the condensation dissipates the white exhaust smoke (steam) is no longer seen.


The combination of the coolant and engine oil will create a milky appearance in the smoke. All it takes is for just a little bit of coolant to get into the combustion chamber for white smoke to be produced. The hydraulic oil that keeps the pressure in your brake system smokes a lot when it comes into contact with something hot (such as your exhaust system or the hot brake discs). But it is always a good idea to keep an eye on your oil and coolant levels on any car, smoke or no smoke. Even in a hot and humid climate, there will be some condensation in the exhaust system overnight.


The car seems to produce white smoke from the exhaust at random (as in not every time I drive). Now i know sometimes this is cause by your valve stem seals are leaking but should i be worried. What should i do about this? On cold winter days, it is common to see white smoke from exhaust pipe as soon as you start the car.


The cause could be a rupture in the breathing tube, which channels air from the combustion chamber to the exhaust port. I have occasional white smoke in my exhaust. I checked the coolant temp and fan functionality and it looks like the fan turns on at about 1degrees I think that is about correct. Bit of bluish white smoke on initial start up, which abated. Shut the car down then helped pack up then played cards with the group for a few hours.


As I left large volumes of bluish white smoke billowed from the exhaust for minutes. Stopping at the park entrance bluish white smoke puffed out of the hoop scoop, turbo side. An engine burning coolant can be easily determined.


First question, do you have to regularly add coolant? The cooler for the EGR valve can leak coolant internally, which causes white smoke to come from the tail pipe. Hot exhaust gases are cooled by the EGR cooler before being circled back into the engine.


Smoke from engine or exhaust Inspection Service You can learn a lot about the health and well being of your car from the color of its exhaust. If it’s operating in tip-top shape, tailpipe emissions should be nearly undetectable.
