The car was fine for about a week after that then the smoke started again, to the point where cars were holding right back away from me when pulling off as it was letting off so much. I took it to a garage they said the guy who fitted my DPF filter obviously didn’t know what he was doing as I had a split vacuum line which he would have noticed when fitting the new filter.
#Remove whitesmoke full
The filter full continue driving warning light kept coming on a few days after having a new one fitted, weird right?! Then I started seeing white smoke coming out from my exhaust on starting the car and then every time I accelerated plus coolant level low warning light even though the tank was full. I have had non stop problems ever since I had an injector seal replaced, a new water hose and a new DPF filter fitted. When the timing is not what it’s supposed to be, your engine will essentially be running rich which will cause fuel to not completely burn and instead exit out of the exhaust as white or gray smoke. #5 – Incorrect Injector Pump Timing (Diesel Engines)Ī diesel engine requires precision timing and fuel pressure of the injector pump. The hard part is figuring out which fuel injector is bad so depending on vehicle mileage, many mechanics will recommend replacing all the injectors since they’re not very expensive in most cases.
Replacing the bad injector (or its o-ring) is the solution. This excess fuel cannot properly burn in the engine and instead comes out as white or gray smoke out of your tailpipe. #4 – Bad Fuel InjectorĪ faulty fuel injector, usually one that is stuck open or is leaking from the o-ring, will deliver too much fuel to the combustion chamber. If the coolant appears to be at the normal level, then you’ll need to have a cooling system pressure checked performed so you can pinpoint where the coolant leaks are coming from. Once the car has had a chance to cool down, check the reservoir and see what the coolant level is at. But if you are trying to fix this yourself, never try to remove the coolant reservoir cap with the car still running because the engine will be too hot and it will cause you serious injury. If you want to fix this white smoke problem, the easy solution is to take your vehicle to the nearest auto body shop as soon as you notice it. The result is a white or light bluish smoke that comes out from exhaust manifold. In this case, bad seals or piston rings cause oil to leak into combustion chamber which then mixes with fuel and burns. Leaking valve seals or piston rings are another possibility when it comes to smoke. This will cause your head gasket to fail because they won’t be able to seal properly when they’re overheated.Īs a result, your engine will get worn out much faster and its internal components will get damaged. Once you have a low coolant level and a cooling system that isn’t being maintained properly, your engine will begin to overheat. All it takes is for just a little bit of coolant to get into the combustion chamber for white smoke to be produced.
The combination of the coolant and engine oil will create a milky appearance in the smoke.
This is how the exhaust smoke ends up turning white.
#Remove whitesmoke crack
Even if the crack is small, the internal coolant can easily leak out and contaminate the oil of your engine. The reason why coolant usually leaks is because there could be a crack in the cylinder head or even engine block. If you the white smoke consistently comes out and the sweet odor smell is present, then it is definitely a problem with your coolant leaking. The most noticeable symptom of internal coolant leakage is when the white smoke is billowing out of the exhaust pipe and leaves a sweet odor in the air.
If you continue to see white smoke coming out of the pipe after the engine has had a chance to warm up or while accelerating, then your coolant might be leaking internally.
#Remove whitesmoke drivers
It’s common for drivers who have lived in a warm climate like California and then move to colder region to worry about this but it’s harmless and perfectly normal. After a short amount of driving, the white smoke should lessen. When the warm or hot exhaust gases meet cold outside air, condensation and steam is a result. When it’s cold outside and you notice white smoke at startup, then you probably have nothing to worry about. This is a common occurrence, especially in colder climates.
