Do you ever see any white smoke passing out from your exhaust pipe? Someone has likely warned you that this is scary, but you should wait a minute or two to see whether it goes away before you freak out. It might just be unharmful condensation if it does. The white smoke results from warm, hot engine air interacting with the cold, outside air. But what if white smoke is coming out all the time? That is a signal towards a severe problem, from bad to worst. Let’s look at the leading causes of bad fuel injector white smoke passing out from your exhaust.
Types of Bad Fuel Injectors White Smoke
Signs of a bad fuel indicator of your vehicle. The symptoms are as follows:
Damaged Cylinder Head
The worst possible cause of white smoke is that it almost always needs the head replacement. Coolant can start leaking internally if your cylinder’s head gets damaged or cracked. Even a minor crack can cause leakage in coolant and merge with engine oil, contaminating it. Dirty engine oil is causing the white smoke to come out from your vehicle’s pipe. Moreover, the characteristic of engine oil is coming out as a sweet odour.
Malfunctioning Engine Control Unit
The engine control unit is your engine’s brain, which controls your vehicle’s functions. If you face any issue, the combustion timing will become entirely off. A skilled specialist will have to reset your ECU if it encounters any problems. Well, this is the root of your white smoke issue. However, the good news is that you won’t have to pay for part replacement unless the ECU itself requires replacement.
Valve Seal or Worn Piston Ring
The seals around the valve and piston ring help to keep the engine oil safe from the combustion chamber. If these go wrong, the oil will start mixing with the fuel and start burning, leading to white smoke. Also, replacing these seals with a top overhaul is intensive work and consequently makes it expensive.
Broken Fuel Injector
The work of a fuel indicator is to pass the fuel into the internal combustion chamber.
Precisely it needs to do at the right time, or else the engine becomes out of time. Moreover, if the fuel does not enter in an improper amount inside the chamber during the combustion, it will cause white smoke. Mainly this problem occurs in diesel engines.
Moreover, used smart car engine fuel injectors which is affordable and easy to replace.
How To Avoid The Causes of Bad Fuel Injector White Smoke?
- You can avoid the symptoms of these lousy fuel injectors by regularly cleaning and maintaining them on your own. At the time of the vehicle’s age, most of the time, carbon occurs in engines and fuel injectors, burns more gas, and gets worse gas mileage.
- Also, the fuel injectors will block and takes more gas than they usually do. There is one tool called ‘Run Right,’ which is used to clean the injectors. Just loosen the top of the device and then pour the cleanser into it completely.
- Therefore, hang the tool on a hood and screw the other end into the fuel rail of a vehicle. Just screws the proper fuel injection rail onto it and at the test port.
- Now, go to the fuse box to take out the fuel pump to turn it off the fuel pump, so that the tool cannot pass the fuel through the engine.
- Moreover, hook the air supply up to strengthen the tool. Then turn on the pressure gauge into the system of about five-pound or lesser than the normal pressure.
- You could see the fuel injector cleaner is going right inside the system. It is done when the cleaner is going out. Now cleaner has done its job. Refer to the below video.
What Are The Types of White Smoke?
The vehicle’s exhaust system ensures that harmful gases pass out safely from the engine. It is your “vehicle’s lungs.”
Typically, white smoke passing out from a vehicle’s exhaust is classified into two types:
Thick White Smoke
Thick white smoke indicates some dead function that needs immediate replacement or repairs of faulty parts. If you continue driving the vehicle in that state, you will risk severe damage to your engine.
Also, the thick white smoke might indicate that water or coolant has unintentionally entered in the combustion chamber (enclosed space inside the vehicle where burning fuel and air mixture). When coolant or water has burned in the block engine (part of an internal combustion engine), it will produce thick white smoke through the exhaust.
Thin White Smoke
Suppose you experienced heavy white smoke from exhaust, especially during winter. Don’t panic because it is entirely normal during cold weather.
However, if you ever notice thick bursts of white smoke coming out from the exhaust, it could indicate that something is happening wrong with the engine components. It is worth checking out, especially when you notice the thick white smoke when you start your vehicle or step towards the accelerator.
Frequently Asked Questions
The worst possible cause of white smoke is that it almost always needs the head replacement. If the fuel injector leaks into cylinder internally, the head will get damaged or cracked. Even a minor crack can cause leakage in coolant and merge with engine oil, contaminating it. However, dirty engine oil is causing white smoke to come out from your vehicle’s pipe.
You can avoid the symptoms of these lousy fuel injectors by regularly cleaning and maintaining them on your own. At the time of the vehicle’s age, most of the time, carbon occurs in engines and fuel injectors, burns more gas, and gets worse gas mileage.
The primary reason for white or black smoke is a fuel pump malfunctioning, making your vehicle’s engine get a rich fuel mixture. In most cases, a bad fuel pump gives a lean variety, which is rare.
