What Is A Spark Plug Non Fouler

A spark plug non fouler is also known as a spark plug anti fouler is a metallic vehicle component that helps to prevent spark plug damage and also aid in fixing spark plug fouling.

The spark plug non fouler usually helps to boost the engine performance, like when the engine runs too rich or when it has oil issues. The spark plug non fouler usually screws onto a spark plug and acts as a sleeve for the plug.

It’s a little hole enough for the gas vapor to ignite and power the engine while keeping the oil or other substances out so it doesn’t foul the plug. Burning oil causes spark plug fouling. The non fouler could function as a short-lived fix for the engine problem.

They stop the spark plugs from getting damaged and repair spark plug fouling if the engine has run too rich or if there are some oil issues. The defouler is formed from top-quality steel that is corrosion-resistant, making it effective for his or her role.

What Is A Spark Plug?

The engine turns energy source (gasoline) into actual movement through a process known as combustion. The engine cycle makes this process happen. In your engine cycle, your valves fill your cylinder with a mixture of air and fuel, which are highly explosive when combined.

As the piston in your engine moves upward, it compresses this mixture until it’s in a tiny space, creating even more potential energy. At the peak of this compression, your engine ignites this mixture with a small spark, creating an explosion that forces the piston back downward, turning the crankshaft in your engine and creating the power which makes your car move forward.

Your spark plugs supply the spark that ignites the air or fuel mixture, creating the explosion which makes your engine produce power.

These small but simple plugs create an arc of electricity across two leads that are not touching, but close enough together that electricity can jump the gap between them.

Your spark plugs, along with the electrical and timing equipment which powers them, are part of what’s known as your ignition system.

Your spark plugs are made from extremely durable material and can withstand millions and millions of explosions before wearing out or needing to be replaced.

But it’s true that over time, the explosions and corrosion lead to smaller or weaker sparks, which leads to reduced efficiency in your engine, and could lead to other issues including misfiring, or failure to fire.

Symptoms Of A Fouled Spark Plug

Understanding the importance of spark plugs, drivers also need to know the symptoms of bad or failing spark plugs. Here are the 4 most common signs:

Poor Fuel Economy

The spark plug provides great help for burning fuel efficiently in the combustion cycle, which can save fuel. However, a bad spark plug will do the opposite.

This is usually because the gap between the spark plug electrodes is too far or too close. So if your car has poor fuel economy, you have a bad spark plug.

Hard To Start The Automobile

It is normal to have some troubles starting your car, but it becomes a common issue, your spark plug might be worn out. Even though the ignition system of the car’s engine is a combination of many components, a spark plug is a place to look.

Misfiring Engine

The ignition system is the part that handles the automobile’s start. So if the engine misfires, car owners know where to look. Two cases might happen problem with either sensor malfunction or spark plug.

This is a serious issue since it will raise exhaust emissions, drop engine power along with fuel economy. It is recommended to contact the mechanics immediately.

Slow Acceleration

Last but not least, slow or poor acceleration is another “victim” of ignition system problems. Even though most of the time, it is the sensor’s fault. However, a bad spark plug sometimes can cause this issue because of the worn-out materials composition.

With this problem, car owners can just replace spark plugs. If acceleration is still slow, there might be other factors that need to be checked by a car mechanic like dirty fuel injector, oxygen sensor issues, terrible fuel filters.

How To Read A Fouled Spark Plug Color

Your car will show many warning signs when there’s a problem with the spark plug. A light tan or gray is the normal spark plug color, but if you see a different color, there may be a problem.

It does the job of igniting the air and fuel mixture in the cylinders by providing sparks. Because of the constant ignition, your vehicle keeps moving. So, you may well understand the importance of this device in keeping the engine running.

A healthy spark plug will have a bit of electrode erosion but no abnormal deposits. While the color would be a light tan, gray, or brownish, it shows the optimal operating condition. What will be the spark plug color when it’s undergoing some problems? Here are the key characteristics to look at.

No Colour

If one or more of these devices do not have a dark brown color or are not colored at all, it suggests that the plugs are not firing at all. A working component must collect some deposits and have a different tone than the original shade. If it happens, check the fuel or ignition.

Ashy Coating

When the center or ground of the spark electrodes is covered with a layer of ash-like substances, check for an oil leak or the quality of the fuel.

The build-up will grow over time and fill in the blank space between two electrodes eventually, causing a misfire. So, if you face this issue, check for leakage or change the oil to the higher grade one.

Black Deposits

If your engine shows poor starting and misfires, check the spark plug color immediately. You can call a blackish build-up at the top as dry or carbon fouling and an oily appearance at the bottom wet fouling.

A clogged cleaner or carburetor, a leak in the vacuum, or the plug’s improper heat range is the probable reason for the first problem while the second one may result from a compromised head gasket or an issue in the valve train.

Glazed White Appearance

If you frequently face power loss at high speeds or when the engine load is high, look at the insulator to see if it turns silvery white.

You may also find a worn-out electrode and minor black deposits. It’s the result of spark plug overheating that may arise from a thin mixture of air and fuel, a vacuum leak, or a poor cooling system.

A Green Shade

It’s a sign of heavy oxidation and leads to poor engine performance because of the gap in creating sparks. We know that there’s lead in the gasoline.

This material creates some chemical reactions with the components in the electrodes and causes corrosion and erosion in the plugs.

Yellowish Brown Deposits

When your engine misfires under hard acceleration or at high RPM, look for a build-up of this color on the insulator nose. The name of this condition is lead fouling, and it appears when the fuel contains too much lead.

How To Fix Oil On Spark Plug Threads In 5 Easy Steps

Don’t freak, if you find oil on spark plug threads because it doesn’t mean that the engine would blow up. It is just a sign that the vehicle’s spark plug tubes are leaking, which needs to be fixed immediately.

So, to follow the repair and maintenance tips of spark plug threads, let’s quickly go through the steps mentioned here.

Systematic Procedure To Remove Oil On Spark Plug Threads

The spark plug drenched in oil will cause the engine to misfire. However, it is important to note that the major culprit here is not the spark plug but the gasket (highly possible), which led to this problem. So, before fixing the oil on a spark plug, make sure you are equipped with the following tools:

Now, once you have all these mechanical components, start straightway with the fixation of oil on spark plug threads.

1. Analyze The Gasket Position And Status

Being a tiny part of the engine, there are the gasket seals. It is an elastic band, which is attached to a specific part of the engine.

The size and shape of the gasket differ according to the component in the vehicle. For instance, there is a head gasket, cylinder gasket, and valve gasket for the components in which they are sealed.

A damaged gasket would let the engine fluids and oil enter the spark plug freely. Hence, it becomes a potent reason for engine misfire in the vehicle.

2. Remove The Spark Plugs And The Valve Cover

Spark plugs are built into the valve cover. Therefore, to change them, the valve cover is to be removed first. So, before this, take out the spark plug tubes and put them on the side.

Once it is done, next take the clamps off the hoses that go to the valve cover using pliers that can easily unlock them. Next, you can use your hands to take the hose out.

After this, remove the wiring harness from the top of the valve cover. Once accomplished, now you can get a big socket and power handle to take the nuts out of the valve cover.

(For this, remove the nuts one by one with the tool, unless it gets easy to remove the one with the fingers.)

Then, get the screwdriver and pry under the valve cover, as it is often stuck on. With the little wiggling and prying, one can easily get it off.

3. Seal Removal

Now, after the valve cover is removed, the seals in each of the spark plugs can be noticed. These seals are the major cause of oil on spark plug threads, which allowed the oil to seep into the spark plug. Remember that before you remove the old seals and valve gasket, you have the new ones in hand.

4. Install The New Valve Cover Gasket

Getting the gasket as per the shape of the component is essential. One must also check the material and the quality of the gasket before purchasing it for the vehicle.

Normally, high-quality silicone material is excellent for the durability of the car and the valve cover gasket. These don’t need changing often, so this not only reduces the work but expenditure, too.

So, once you have it, first add a liquid called sealer at the edges so the new gasket doesn’t slip over. In addition, the gasket placed over the liquid sealer will truss its place thus, preventing the entrance of oil on the spark plug.

5. Installation Of Spark Plug Gasket

Lastly, one needs to place the spark plug gasket on the rim of the spark plug well. These are circular, which are placed in the same manner using the liquid sealant as the valve cover gasket. Once finished with it, now bolt the nuts in the order 2-3-1-4 that were removed earlier, to avoid any damage to the valve cover.

Reliability Of Spark Plugs

Most vehicles nowadays come packaged with extended-life spark plugs produced from factory. These spark plugs are much more expensive than conventional ones. This is because they have an extended lifespan of up to 100,000 miles.

As the spark plug approaches closer to the end of its lifespan, the gap in between the two leads widens, resulting in reduced efficacy and higher chances of a misfire. A corroded and broken spark plug can significantly damage the engine cylinder’s interior, leading to a costly repair.

Installation Of Spark Plug Non Fouler

Installing the spark plug anti-fouler might be a typical thing to do, but not when it’s cleaned out the proper way. But, before you begin the whole installation procedure, don’t forget to possess all tools near you. So, let’s get started!

Fit The Sensor

Your car can have room for either of two spark plug non-fouler. If you would like to put it into one spark plug, it’s preferable to possess an electrical drill machine by your side. Once you are bent by the spark plug, choose a minimum of 18mm in size.

To start the installation, reset your ECU (Engine Control Unit) by disconnecting the negative terminal on the battery. Drill down the middle of 1 non-fouler to the half by taking it out. Doing this can make enough space for the sensor to suit inside it easily.

Reinstall & Reconnect

Get the sensor and reinstall it by implementing amazing anti-grab on the thread. Now, it’s time to reconnect the whole ECU system to the battery. You’ve got just installed the whole spark plug non-fouler system by yourself.

In case you would like to make the installation fail-proof, use these upkeep tips as well. If you’ve got too tight a non-fouler, this complete method is the thing to undertake.

Screw Spark Plug & Unscrew Sensor

After successfully locating the sensor inside the spark plug non-fouler, screw it to the tight on the crest of the first. To make the entire setup easy to remove, it’s useful to use or apply an anti-grab product on the strand.

Presently, separate it from the stock sensor, place the cell stick in, and repeatedly use some anti-grab. Take a towel or any cleaning product to dirt-free the completed cell. Confirm that you simply don’t leave one spot uncleaned because it might end in further issues.

Can Engine Run Without Spark Plug?

The answer is No. A spark plug connects with the engine for petrol or gasoline to create the smooth performance of the engine, as well as the whole car. Without a working spark plug, the combustion cycle of your vehicle cannot run and function normally, which could lead to various issues.

Spark Plug Non Fouler For Oxygen Sensors

The engine comprises a fuel injection computer that regulates fuel transfer to the engine through the oxygen sensors. The sensors are next to the catalytic converter and there are usually 2 to 4 in modern cars. Those vehicles older than 20 years have one or no O2 sensors.

The right amount of fuel ensures effective combustion, optimum performance, and controlled emissions. Other O2 sensors can be screwed onto the exhaust pipe past the catalytic converter to check on the catalytic converter. It ensures last traces of pollution from the exhaust are scrubbed.

These O2 sensors form part of this entire system and have a P0420 error code doesn’t mean the O2 sensors or catalytic converter are faulty.

Spark Plug Non Fouler using an OBDII scanner diagnostics tool to find a trouble code P0420

The spark plug non fouler has been used as a cheap and temporary fix for the P0420/catalytic efficacy code instead of replacing the catalytic converter or other expensive repairs. This can be an illegal fix in some states where emission test is used to pass.

Usage of 2 spark plug non fouler has been perceived as ineffective since you still end up with MIL Light on as the ECM detects an inactive O2 sensor. It compared to having the O2 sensor plugged while leaving it attached to the harness.

Error codes P0420, P0135, and P0141 that point to the oxygen sensor should just be the diagnosing the problem. A quick replacement should be done to and putting in a spark plug no fouler doesn’t guarantee efficacy.

Steps In Using The Spark Plug Non Fouler For O2 Sensors

Some have done the trick successfully by using a drill, ½ drill bit of steel, a wrench, hammer, or mallet, and 18 mm spark plug non-fouler No. 42009 that comes in part from AutoZone.

The first step is to remove the rear cat O2 sensors or the second O2 sensor, which is not a straightforward task. The sensor is usually found right after the catalytic converter. You may also use an oxygen sensor socket and a used 2-foot metal pipe as an extender over the ratchet wrench to give you the torque to get the thing off when a hammer and wrench wouldn’t work.

The next step is to put the spark plug non-fouler against something steady and drill the non-fouler enough for the Oxygen sensor to slide inside at approximately ½ inch. Take it nice and slow, as with drilling other metals, and put some lubricant to the metal a few times during the drill so your drill will not dull quickly.

Next, is to finally screw the spark non-fouler onto the sensor. Go with the one that was drilled out first. Screw it onto the O2 sensor where it screws into the catalytic converter/exhaust pipe. And then take the second non-fouler and screw it on the top of the other one. Last, all you need to do is put things back up onto the catalytic converter.

Spark Plug Non Fouler FAQs

Here are some of the most commonly asked questions regarding the spark plug non fouler.

What Size Socket Do I Need For A Spark Plug?

There are two sizes for spark plug sockets: 13/16 inches and â…ť inches. Remember to check the rubber insert since it helps to hold the plug in place. To perform the installation, drivers might need a socket wrench, a universal joint, and finally, a spark plug socket.

Can I Drive With A Bad Spark Plug?

You can, but you should not. Drivers can still be able to start your car, yet damaged or worn-out spark plugs can damage the engine, which might lead to heavy costs later.

What Happens If You Don’t Change Your Spark Plugs?

Since spark plugs will deteriorate over time, various problems will arise if car owners forget to replace them. Since the spark plug goes off, the mixture between air and fuel will be incomplete, which leads to engine power loss.

Can A Spark Plug Kill You?

A spark plug, even though small, has a lot of voltage. However, car owners can only get a shock from it if the engine is still running, so always be careful with the engine before installing or replacing spark plugs.

Spark Plug Non Fouler – Conclusion

Spark plug non-fouler is an invention made in heaven. They’re an inexpensive fix, saving you plenty of money, but bear in mind that they’re only a fast and temporary fix for your spark plug or your O2 sensors.
