what do different colored exhaust smokes coming out of exhaust pipe mean?? Diagnose this problem at PartsAvatar.

Learn how toquickly check your car’s health from the color of the smoke emitted by your car exhaust – Tips from Partsavatar Aftermarket Parts.

You can easily determine an auto malfunction from the smoke emissions. It is definitely time to pay attention to your car if you notice smoke of different colors emitting from exhaust tailpipe.

Not all type of smokes determine auto malfunction. In some cases, if you notice a large amount of smoke coming out of car exhaust pipe, you would more or less consider that something is wrong with your car’s engine. But it is to be noted that it is not always the same case. Not all automotive problems can be detected from smoke types. But still, how do you know that the smoke is ruining your engine? When do you think is the time to visit the mechanic once you notice smoke?

Parts Avatar gives you the answer. In this article, we shall differentiate between different colored auto smokes that you must be familiar with along with their causes.

What are the Causes of Smoke?

First and foremost let us know why the smoke is produced before analyzing different colors of smoke. If there is some problem with the engine that produces smoke, that smoke makes its exit through the exhaust.

Sometimes, fire under the hood produces engine smoke and in the worst case flames may start coming out which could lead to a disaster. Do yourself a favor and get far away from your car if you notice something like this. It is foolish decision to keep on driving as it will eventually become risky for your safety.

Oil dripping from leaking valve cover gasket into the hot manifold may also produce smoke. You will also notice oil pooling under the car or the driveway if the leak is large.You can replace car valve cover gasket under aftermarket prices which are quite cheap.

So, not always there is issue with engine. But to begin with, smoke is not a good sign. Hand over your car to a certified technician and let him figure out what to do. Now let us discuss causes of different colored smoke emitted out of exhaust.

White Exhaust Smoke

Sometimes small amount of condensed vapors come out of exhaust in the form of white smoke. It is not that dangerous though. Vapors quickly dissipate in the atmosphere after exiting car exhaust tailpipe. But if your car is producing frequent thick white smoke, then it might be alarming.There is possibility that coolant might be burning inside the internal combustion chamber. There are various causes behind this as follows.

Cylinder Head

As the combustion chamber is located in the cylinder head, most explosive processes take place in here.Engine misfires are always caused due to cracks in cylinder head.

The crack in the cylinder head causes the coolant to enter the combustion chamber.

Due to too much heat inside the chamber, overheating can be caused. Due to immense heat, a lot of stress is put on cylinder head. As the cooling system has already failed and pressure has been built, this whole scenario causes the head gasket to malfunction and the cylinder head starts to crack. When the mixture of coolant and fuel is burnt for combustion process, it produces white smoke.

Auto Cylinder heads are one of the car’s costly repairs. Your car may need complete replacement of cylinder head. If the cylinder heads are ignored, by time the damage is so big that you might need to consider buying a new car.

Blown Head Gasket

The basic purpose of head gasket is to seal the block and the cylinder head. Often a damaged head gasket or cracks in the engine block makes passage for the coolant to enter the combustion chamber and get mixed with the fuel. Thus white smoke is produced. car's engine Head gaskets are cheap to purchase but at the same time costly when it comes to the labor.

Cracked engine block

A crack in the deck of engine block near the coolant jacket will cause the coolant to enter the combustion chamber.Cracked engine block can become a grave problem for your car’s engine. It is virtually impossible to repair a cracked engine block. Engine block supports almost all the components of the engine.

A crack in the block will cause huge leakages making your car emit white smoke. It is better to get an engine replacement as a whole.

It is to be noted that emission of white smoke is the first sign of engine overheating problem.Overheating of engine can lead to massive auto component damage under the hood. So call your mechanic immediately.

Gray/Blue Exhaust Smoke

A malfunctioning turbocharger or burning of oil in the combustion chamber can cause the exhaust to emit blue smoke.You might need to replace turbocharger of your car if it is faulty.These are possible symptoms.

Transmission fluid leakage

The transmission fluid used by your vehicle’s transmission might be leaking and getting mixed with the oil or fuel and getting burnt. A malfunctioning transmission vacuum modulator may be the culprit here which is causing the leakage and burning.

Leaking Valve stem seal

The valve stems regulate the oil to lubricate the guides in the chamber. Grey emissions might be produced due to faulty stem seals as they make the way for the oil to enter the combustion chamber. The best way is to either replace Auto Valve stem seal set or just replace the engine if the damage is quite big. Worn or damaged piston rings, damaged valve guides also cause grey smoke to be emitted out of the exhaust.Replace car's piston rings in combustion chamber too.

Stuck PCV Valve

Blue or gray smoke could also be produced due to immense crankcase pressure caused by the stuck PCV Valve. Stuck valve may cause oil leakage into the chamber thus producing grey fumes. If they are loose, tighten PCV Valve of car and check whether the smoke persists. Otherwise call your mechanic for better advice.

Black Exhaust Smoke

Burning of excessive fuel in the engine often causes the black exhaust smoke to emit. This means that too much gas is entering the chamber but only small amount of fuel is being burnt. In this case fill your gas tank with relevant amount of fuel. Let us take a look at some other causes.

Dirty Air filter

The air filter allows the oxygen to enter the combustion chamber and blocks other substances from entering the chamber. But if it is clogged, less air is allowed in the chamber resulting in your car burning too much fuel with small amount of oxygen which results in black smoke. It is better to replace the car air filter if you notice any symptom of malfunction.

Faulty Fuel Pressure Regulator

Our car’s fuel system is designed to work in different range of pressures.The fuel pressure regulator controls the pressure with which your car runs. A faulty regulator may cause the pressure to fluctuate and if it falls too low then there may not be enough fuel reaching the engine to start it. Replace the fuel pressure regulator if necessary.

Clogged Fuel injectors

Fuel injectors are the devices that are used to spray small amount of atomized gasoline into the vehicle’s Engine intake manifold which is meant to mix with the oxygen to start your car’s engine. A faulty fuel injector will cause too much fuel to leak inside the chamber which in turn produces black smoke. The remedy is to repair the auto fuel injectors.

Fuel Return

A restricted fuel return line allows too much fuel to be dissipated for combustion purposes. If the amount of fuel for combustion is higher than normal, more fuel will be burnt and the rate of burnt gases leaving the combustion chamber will also increase resulting in black smoke.

Burning excessive fuel will affect your car’s fuel economy. So pay attention to what it needs to ensure more miles for your car.

Bottom line

If your vehicle is running on too much oil, engine is burning too much oil or if you notice oil or coolant leakage, then there is a possibility that your engine is malfunctioning.

Smoke depicts that the car is in distress. Always diagnose what needs to be repaired and beware of the fake auto repair shops. Take advice from a professional or even take second opinion. Don’t wait for the engine light to flash.

Keep an eye on the smoke emitter by your car’s exhaust and keep proper level of Auto transmission fluid and coolant of car in your car.

Intake manifold's perfect tuning and choice- key to car’s performance

Intake manifolds are often overlooked but they play a very crucial role in the ability of the engine to produce power. Selecting right kind of intake manifold is the first step to maximum performance of engine.

Intake manifold is also known as car's Inlet manifold. It is the part of an engine that supplies fuel-air mixture to the cylinders. The simplest change can drastically alter engine’s performance.

Its main function is to distribute the combustion mixture to each intake port in the cylinder head. Even distribution is important for increasing performance and efficiency of the engine. It may also serve as the mount for throttle body, car's carburetor and other engine components.

This auto part takes single air inlet and distributes it to each of the individual cylinders. As the piston moves down the cylinder during the intake stroke, it is actually pulling an air – fuel mixture through intake valve. The fuel, right before entering the cylinder, is injected with a fuel injector into the intake manifold runner.

It is advised to not to ignore intake manifold as it is fully responsible for car’s internal combustion. Without it, your engine is just useless.

Engine is just like human body. It needs to breathe more efficiently to get more power out of the car. Intake manifolds distribute air to cylinders evenly. In old vehicles, each cylinder has a runner that delivers the air to them through intake valves. If your intake runner has a large diameter then you will probably experience high horsepower. But for small diameters they will provide with less power. In the old cars, carburetor sits on the top of intake manifold and sends both the air and fuel to the cylinder head. For multi point injected engines it holds fuel injector. Long runners are good for low end powers while short one are good when you need power in upper registers of your power band.

For the engine to work efficiently it is very important to check whether the engine is having right amount of air- fuel mixture. To check correct air to fuel mixture ratio some engines are already deployed with a number of systems that help in converting the fuel into motion. Intake manifold plays the main role of managing the air necessary for engine cylinders to operate.

In some engines with no fuel injection, the intake manifold evenly distributes air- fuel mixture through engine’s combustion chambers.

For smooth operation of an engine intake manifold design is very important. The fuel charge distributed should be of same quality and strength for better results. There are different types of manifolds so not every manifold perform the task in same way. So it is quite necessary to choose right kind of intake manifold that could further enhance your engine and combustion system.

WHEN TO REPLACE YOUR INTAKE MANIFOLD

Today’s cars generally have intake manifolds made of plastic material. In old cars it was made of aluminum or cast iron. Symptoms of a bad intake manifold are:

Plastic may crack, warp or even have bad gasket overtime.

Hard starting, stumbling during acceleration are some of the symptoms of bad intake manifold. Engine light will start beaming if it detects the engine running too lean or getting too much air. This situation can be caused by leak in intake manifold.

A premature detonation in the cylinder will lead to major damage of the engine.

Thus it is necessary for the drivers to check the condition of intake manifold timely. By detecting these symptoms you can get your intake manifold checked or replaced before it could further damage your engine. It will save your money and time.

MODIFICATION FOR FINE TUNING OF INTAKE MANIFOLDS

Various adjustments can be applied to intake manifolds to fine tune them for specific performance requirements.

1. Re-jet the carburetor of car and notice the timing reduction based on improvement to air- fuel mixture quality.

2. Re texture the runner and plenum surface areas if they are grounded or polished.

3. It is necessary for the high speed power to match intake manifold to the cylinder head. Not doing so will result in bad runner velocity.

4. You can also use single plane intakes to improve fuel distribution in problem runners. They can also use modified brotix turtles that can be shaped according to flow requirements.

5. The proper alignment of the runner must be ensured by all means possible.

6. Check gasket fit to ensure that it does not overhang port openings. Water passages should also be examined for any leakage.

7. As every manifold provides different function so for throttle response improvement, a different manifold may be needed. So make sure you do not opt for single plane manifold.

8. On engines that have been run, examine the plenums and runners for the signs of reversion or fuel suspension. Colored stain indicates separation and darker stain indicates reversion.

For the good performance of the engine, it is very important for the drivers to examine their intake manifolds and get them replaced before things go out of your hands.
