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 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.
