What Is An EVAP Smoke Machine For Cars

The EVAP system is installed in a car’s engine to prevent fuel vapors from leaking from the fuel system and seeping out of your car. If there is any leak, it will not be easy to find since there are many possibilities.

The leak can occur anywhere inside the EVAP system, including the purge valve, hose, fuel tank, and canister. That is when an EVAP smoke machine comes in handy.

An EVAP smoke machine is a machine that blows smoke inside the car. With the help of that smoke, you can identify where the leak is. The smoke will show you exactly which components to check. So, you will not have to do a complete checkup of the car.

How Does A Car Smoke Machine Work

When you think about a leak in the car, it is not just the fuel you should be worried about. Vacuum leaks are also worrying when checked properly. A vacuum leak is one of the many reasons for a check engine light to flash.

A smoke test is one of the most effective techniques to specify whether a car has too much pressure in the EVAP system. It can also help detect if any components inside the vehicle are leaking. A car smoke test is performed by technicians to detect any leaks in the automobile’s hollow sections. It can be the intake manifold, the EVAP system, or the exhaust system.

Using a car smoke machine is very easy. All you need to do is simply blow smoke into the different components of the system to check whether they are leaking.

What do you do when you are trying to find a leak in a big bucket? You fill it with water and see where the water is leaking from. A car smoke test is just the same. Instead of water, you use smoke to check for leaks in the car’s components.

EVAP smoke testing efficiently pinpoints the problem when there is a leak in the vacuum system of your car. The process might seem simple, but it can cost a lot if you get a smoke test done by a professional mechanic. So, having your smoke machine at home is better than rushing to the mechanic.

What Are the Symptoms Of An EVAP Leak

1. Check Engine Light

The first sign of any problem with a car is the flashing of the check engine light. The check engine light is not the most reliable way to detect an issue. There are way too many possibilities for a check engine light to flash.

But an EVAP leak is one of these reasons. So, look out for the check engine light. Get a diagnostic tool scanner to read the trouble code. Then you can figure out whether there is a vacuum leak or not.

2. Fuel Odor

A glaring symptom of an EVAP leak can be the unwanted smell of fuel. If you can smell the fuel when you turn the car ignition, there is a high possibility of EVAP leakage. The energy in your car may be liquid, but it does transform into a gas form.

When there is a leak inside your car, it is common for that evaporated gas to leak. The smell of unmistakable fuel is enough to indicate that there is a leak in the EVAP system. If you can smell the fuel, it is better to get your vehicle checked right away.

3. Increased Fuel Consumption

If your EVAP system has gaps, fuel vapors will slowly leak out of your car’s fuel system. For the most part, the fuel vapor leaks are minuscule at a time, as it’s mostly leaking molecules. But over time, these vapors and molecules will add up to become significant enough to impact your car’s MPG.

As a result, you will notice higher fuel consumption. That will lead to a more frequent visit to the fuel pump and spending more money on gas than usual.

4. Issue With Ignition

Air can seep into the fuel system when there is any leak inside the engine. So, that can cause a delay or problem with starting the car. But an ignition issue does not always indicate a vacuum leak. Other components might be responsible for that. So, it is better to get a diagnosis of your car.

Why Do You Need A Smoke Machine For Cars

The check engine light on your car dashboard might tell you something is wrong with the car. But it will not tell you what is wrong. Without proper diagnostics, it is impossible to pinpoint the issue causing the check engine light to flash.

A vacuum leak inside the car is a common problem. If it is a small leak, you might not even notice it. But letting it fester can result in something disastrous. Car owners often neglect minor signs at times. They do not want to deal with the hassle of going to the workshop and finding out it is nothing.

That is why self-diagnosis is essential. And for a proper vacuum leak check, you need an excellent car smoke machine. A vacuum leak check by professional costs you more than some of the affordable smoke machines on the market. So, it is clear that buying a smoke machine is worth it.

Is It Safe To Drive A Car With An EVAP Leak

An EVAP leak will not seem dangerous at first. It does not affect the drivability of a car right away. With an EVAP leak, you can still drive around in your vehicle. But it is not what we would recommend.

A vacuum leak in the car may seem like a minor problem. But it can also lead to significant engine problems if left unchecked. If you don’t find out the root of the leaks, there’s no way of knowing the severity of the situation.

Smoke Machine For Cars

It is not wise to ignore a check engine light no matter how trivial the issue seems. Just take some time out of your schedule and make a quick diagnosis of the car. You can run some initial tests with the proper tools at home. For example, you can do a smoke test on your vehicle if you have a smoke machine.

Otherwise, you have to get your car looked over by a professional. With a self-diagnosis, you can understand the gravity of the problem. It will save you a lot of time and money if you know the issues in your car before visiting a mechanic.

Buying Guide

1. Smoke Fluid In Machine

Any good smoke machine can have exclusive smoke fluid included in the package. The bottle you get may last you multiple times, but you will run out eventually. If it is some premium-level smoke fluid, it will cost you a lot to buy a new bottle.

So, using a machine compatible with normal fluids like baby oil or mineral oil is better.

2. Weight And Durability

The weight of a smoke machine is rather essential. The device needs to be handled by hand. You have to carry it over to your car every time you want to do a smoke test. So, if the machine is too heavy or bulky, it will be hard to move around.

So, you need a smoke machine that is lightweight and portable. As for durability, most car smoke machines from well-known brands have excellent build quality. They are made to last for several years.

Still, looking at the materials before buying a smoke machine is better. Take a look at the warranty provided by the manufacturer as well.

3. Ease Of Use

A smoke machine is pretty simple to operate. You might require extra tools to make the machine work. You can always look for tutorial videos or guidelines online.

Consider that certain manufacturers can void the warranty if an untrained user handles and destroys the machine.

4. Hose Diameter And Attachments

Not all smoke machines come with additional attachments or adapters. Check the diameter of your malfunctioning pipeline to that of the smoke machine you wish to buy. See that it is at least as significant, if not more expansive than the pipe you want to inspect.

5. Smoke Output

Smoke output is an essential factor when it comes to buying a smoke machine. EVAP smoke machines come with nozzles from where the smoke is discharged. The released smoke tells you where the leak is inside the car components.

But it is vital to have some control over the smoke output. Some machines do not have an adjustment for the smoke output. In that case, you will always be stuck with heavy and thick smoke output. It might not be the most effective in some instances.

So, looking for a smoke machine with a smoke output adjustment is better. Then you can adjust the thickness of the smoke release to detect the leaks with utmost accuracy.

6. Pricing

A smoke machine for cars can cost anywhere between $50 and 1500. It all depends on the brand and features of the smoke machine. But no matter which product you go for, a smoke machine is a worthy investment.

With smoke machines, it is easy to keep an eye on the car’s vacuum system. If the EVAP system in your car malfunctions, the repair cost might be much higher than a smoke machine. An EVAP system repair will cost around $250-400, not to mention the labor cost.

So, it is better to stop contemplating whether to invest your money in buying a car smoke machine or not. Pick one according to your preferences and stay within your budget.

Bottom Line

A car smoke machine allows you to assess any EVAP leak from the comfort of your home. Also, the next time you notice a problem with your car’s engine, you have your car smoke machine diagnose it.

After much research, we compiled this list of the best smoke machines for cars. We hope you can make an informed decision on the most delicate car smoke machine. As mentioned above, see that all the features meet your requirements when purchasing a smoke machine.
