How to Fix Carbon Build Up in Engine? – The Ultimate Guide

While hanging out with friends, there is a higher chance that you might have heard about clearing the carbon. You might have just gone with the flow in the conversation but do you exactly know what carbon build-up is? If so, do you know how to fix carbon build up in engine?

Because if you do not have proper knowledge about that, you might end up with a non-functional engine relatively soon. And no one wants to go through the expense of fixing up the entire engine for something that they could have avoided, right? Well, that is why we are here.

We are going to describe everything that you need to know regarding carbon deposits and describe the process of fixing the build-up. So, continue reading.

What Exactly Is a Carbon Deposit or Build Up?

Think of a fireplace or a BBQ pit that is constantly going through the combustion process. Throughout the time, the by-product of wood is going to coat the sides, right? Well, the same thing is applicable to the engine. But instead of the wood, the oil is going to leave carbon deposits on the essential parts of the engine.

And by essential, we are referring to the intake, exhaust, and cylinders of the engine. If they get clogged up, the performance will degrade significantly throughout the time.

How to Check If Your Engine Is Getting Choked with Carbon Deposits?

The symptoms will not come up during the early stage. It will show up once the condition gets worse. The first sign that you will notice that the engine is a bit rough while idling. Also, the acceleration will start to get poor throughout time.

Other than that, if the engine starts pinging and knocking while running, there is a high chance that carbon has started to build up or might have already deposited on the inside.

What to Do to Lower the Chances of Carbon Getting Deposited Inside the Engine?

You might have heard the phrase that prevention is always better than cure. Well, there is a thing that you can do to prevent the carbon from getting deposited inside the engine. And that would save you from going through the process of fixing the engine.

Most of the engine and petrol oils are now formulated with some sort of additive. This additive is going to go a long way in terms of keeping the carbon build-up in check. So, to prevent the build-ups from happening or to clear them out in some cases, you need to use quality engine oil.

Now, if you are wondering what the formulation is going to be, it is basically a degree of detergency that will clear out the deposits or prevent the carbon from getting deposited.

Steps to Follow to Fix a Carbon Build Up Inside the Engine

Once you are sure that there is a carbon deposit inside the engine, you need to work on getting the inside fixed and clear of the deposits. And there are two different ways. They are as stated:

For Minimal Build Up

If the build-up is not at the extreme level yet, it would be possible to clear them out using fuel additives. You will find plenty of these in the market. And each of them will have a different formulation. Opt for the ones that are tested and have a higher-quality rating. Those are going to work the best in clearing the deposits.

On that note, to ensure that the oil is doing a proper job in terms of preventing further build-ups, you need to redline the engine every two or three hundred km. Revving or redlining the engine until the tachometer hits the very limit will help burn off the carbon build-up.

Nevertheless, you should only follow the redlining process while the engine is in optimal condition and is performing adequately. Do not rev the engine to the max when it is too hot or too cold.

For Extreme Build Up

Now, if the build-up has reached a very extreme level, you need to get it fixed by a trusted mechanic. Do not attempt to clean the build-up by yourself if you do not have that much experience because that will only make the place a mess.

For cleaning the engine by yourself, remove the spark plug, muffler, guard, and other components. Lift the cylinder head and start scraping the carbon deposits off using a plastic or a wooden scraper. Once most of the carbons are cleared out, clear the rest out using a solvent.

Do make sure that each of the valve seats and the valve is clear before placing the cylinder head back into the position. Then put the rest of the components back into place.

Final Words

Now that you know how to fix carbon build up in engine, you can keep the inside clean and ensure that the engine offers optimal performance throughout its lifespan. In fact, you can enhance its lifespan significantly by clearing out the carbons following the process we described above.
