How To Clean Pistons Without Removing Them?

Yes. You can clean Pistons without removing them.

Numerous specialists and supervisors are aware that extreme combustion chamber carbon build-up can cause critical driveability issues with the engines. 

You’d have probably seen the hardened carbon chunk on the spark plug of engines or atop piston and valves in the combustion chamber. These deposits are undesirable and, over a certain period, can become unavoidable.

This gunk is likely to accumulate from the oil that leaks into the combustion chamber, which partially burns as the engine runs. As a result, carbon residue accumulates on the surface that reduces space in the compartment and can increase the engine’s compression ratio.

It might come as increased oil utilization, decreased gas mileage, and now and again, inevitable engine failures.

This article will show you how to clean pistons against carbon build-up to increase your engine’s efficiency and life.

Read on to discover the step-by-step guide. But before jumping into that section, let’s know the function of the piston and why cleaning it is crucial.

Function of Piston

The piston is the fundamental part of internal combustion chambers. It converts heat energy into mechanical energy and has a reciprocating function.

It moves up and down inside the cylinder when the motor produces power. The motivation behind the piston is to stand the development of gases and send it to the driving rod. 

It moves the power of the blast to the driving rod and, thus, rotates it. The piston accompanies rings that act as a seal among it and the cylinder divider.

Steps to Clean Your Pistons

The following steps elaborate briefly on the process of cleaning pistons without removing any internal parts.

Step 1: Switching Off the Engine.

Ensure the ignition is off and the parking of the vehicle is in a ventilated area. Stopping in an empty, spacious place will allow you to take advantage of light and movement.

Detach the air intake duct from the throttle body. That can help remove carbon efficiently. You can utilize this by spraying through it, and this will remove carbon residues formed on the throttle body.

Step 2: Cleaning the Fuel Rail

After you disengage the air intake, you need to clean the fuel rail. Do this by separating the fuel rail that associates the gas tank to the infusion rail. Use infusion pressure injection to clean the fuel rails.

To explain it further, follow these steps:

  • Disconnect fuel rail from fuel injectors. Reach to the fuel pump onto the side of the engine and pull-out fuel injectors.
  • Disengage the pressure regulator vacuum if there is one.
  • Remove fuel tank cap to prevent the build-up of pressure. That is because the cleaner will clean by bursting the cleaners into fuel injectors. Removing the cap will prevent excessive pressure build-up that can lead to combustion.
  • Turn on the vehicle to let the cleaners into fuel injectors. Let it run until it stops running by itself when the cleaning fluid gets consumed.
  • Remove the cleaning kit and attach back the injectors and fuel pumps.
  • You can turn on the ignition to check whether you re-attached the parts correctly.

Step 3: Use Fuel Enhancer

Add the fuel enhancer and let it dilute. It will move through the fuel stream and clear out whatever build-up is left.

However, you need to take care of the fuel enhancer quality. Inconsistent fuel quality leads to carbon residues building up.

Fuel enhancers also prevent dirty injector deposits, which reduce the flow and combustion of fuel.

Step 4: Use Engine Oil

A small amount of carbon residue will leave out during a complete internal-combustion cycle while the engine runs. The left-over fuel gets heated up, polymerizes, and reacts with air to form carbon deposits.

One of the best ways to prevent carbon accumulation is to flush them out whenever possible.  You can do this using additives such as Marvel Mystery Oil and Seafoam Oil.

These products soften and flush the stubborn carbon gunk.

Add to the engine oil in the vehicle and allow it to run for an hour or so. After this, you will replace the oil with a new one, and you are good to go.

Step 5: Increase Engine Oil

Increasing engine oil refrains the carbon residue formation. You can use Oil enhancer products. They usually contain antioxidants in their formula. 

Besides, there are many high-mileage oils that are designed to remove sludge from engines. Some recommended high-mileage oils to reduce the carbon build-up are: Valvoline high-mileage oil, Pennzoil high-mileage motor oil and Quaker state motor oil.

Add the oil enhance products right after changing oil.

How to Know if Your Pistons are Foul?

There are sure signs that will show up when you have a dirty piston.

The critical among which are:

  • Excessive Emission of Smoke 

When the pistons are bad, oil starts to leak and burns. The oil that has spread will cause the engine to emit grey and white smoke fumes. The smell of burning fat often accompanies this.

  • Increased Oil Consumption

If you have too often pay for oil than usual, it can be a sign of a bad piston.

Since oil leaks, there may be less or no oil left for burning.

  • Acceleration

Another sign that your cylinders are terrible is the point at which you begin to see a lessening in your vehicle’s force. You may not realize the seriousness of the situation not until the car refuses to move. That occurs because of the decrease in the pressure occurring in your motor. Thus, the vehicle takes quite a long to accelerate at whatever point you hit the gas pedal.

This slow performance, however, can also be a result of worn-out shocks. To counter this, you should use high-quality shock absorbers such as Monroe and KYB shocks.

What are the Causes of Carbon Build-up?

The carbon build-up is the result of low-quality fuel mixed with leaking oil. The leaking oil is mainly caused due to hole in the radiator that can be stopped using leak sealants such as Bar’s Leaks Block Seal Liquid Copper Intake and Radiator Stop Leak and K-Seal Multi-Purpose Permanent Coolant Leak Repair.

 Some of the prime reasons of build-up are:

  • You utilize excessive added substances and inferior quality substances both in oil and fuel.
  • You utilize low-quality fuel 
  • Oil change lines get harmed
  • The vehicle runs with an expanded motor warmth system;
  • You drive brief distances

These deposits may pose dangers to the engine. Carbon deposits can ingest fuel, bringing about an inappropriate fuel-air separation and engine explosion. 

Soot on the piston’s surface and compression rings can also lead to the wearing of the cylinder. These will firstly deprive the rings of their mobility. That can cause compression and lead to oil consumption.

With time, pressure on cylinders can increase.

Apart from carbon build-up there are another major issue that you should pay attention to such as corrosion of metal parts of your vehicle and overheating of engine. While corrosion can be prevented by using rust converters., overheating can be reduced by using suitable radiator fans.

How Can Carbon Build-up be Prevented?

There are specific methods that you can use to prevent carbon accumulation. The essential way is getting regular oil changes and using quality oils.

The present petroleum and engine oils are planned with added substances to help hold carbon build-up under control. Ensure that you utilize quality fuels and replace your oil as per the manufacturer’s suggestion. 

Decent engine oil is defined with a level of detergency to tidy up these build-ups. At that point, the carbon deposits will be pulled away from the metal parts and caught in the oil channel. 

That highlights the significance of replacing your oil and channel consistently.

How to Clean Carbon Off the Engine Parts?

You clean carbon from engine parts by utilizing an intake system cleaner. 

The cleaner is splashed into the throttle body while the motor is running. Some different cleaners may expect you to spray into intake straightforwardly. For this situation, empty the cleaner gradually into the hose while the engine is running. 

Turn on the engine at 1,000 to 1,500 RPM while showering the cleaner into the complex of the intake. The interaction may take 10 to 20 minutes. 

This interaction may depend upon how filthy the valves are and the adequacy of the cleaning substance to eliminate the carbon deposits. 

If the cycle fails, attempt a more straightforward cleaning approach. You need to have sufficient experience to go through this cycle. 

That is because you will have to remove the intake manifold for you to apply the cleaner directly to the valves. You might need expert advice to do so.

You can also clean up the carbon by removing the cylinder heads and performing a valve job. 

Another method used to eliminate carbon is carburetor cleaners.

Many advanced vehicles use injectors to control fuel streams, yet more older models use carburetors. At the point when it gets dirty, the fuel control system will fail. 

For this situation, you can utilize carburetor cleaners that contain solid Aerosols. These are the best solvents for eliminating carbon out of the carburetors and keeping them in excellent condition.

When the carbon gets eliminated from the valves, you will promptly see a difference in the way your engine performs.

Final Words

The article, it is very clearly discussed the cleaning of pistons without removing them. There are prevention methods also described preventing any carbon build-up in the future using various methods. 

Following these simple steps can save your engine parts from damage. It will help you remove the black gunk that can otherwise make your engine sick. Moreover, it will keep you from wrecking your wallet.

However, if you are not aware of the process, seek expert advice. Using wrong products and substances may lead to much more damage to your engine.
