Bad Timing Chain Tensioner Symptoms and Replacement Cost?

Bad timing chain tensioner symptoms and everything related to the repair are covered in the guide sections below to help you learn how to identify the issues with your timing chain. Moreover, you need to know precisely what the problem with the component is so that you can take the necessary precautions and solve the proper process to fix it accordingly.

The functionality of your vehicle heavily depends on your timing chain, as it keeps the internal components working and ensures a good performance of the car overall, and it could be hazardous if something is wrong with it. In the guide below, we will take an in-depth look at how you can learn to identify the signs of a bad timing chain and the techniques to fix and replace it!

How Can You Fix a Bad Timing Chain via Replacement?

You can fix a bad timing chain via replacement by having the vehicle thoroughly evaluated by a professional. When you decide to replace it, you will need to know the expenses you will incur, which will vary depending on the quality and complexity of the component.

– Getting a Professional Evaluation

To fix a bad timing chain by replacing it, you can use the help of a professional evaluation. All of the timing chain systems have been made to tolerate the vehicle’s life. You do not need to replace your chain until after a certain period of time.

On the other hand, if any of the noise symptoms or issues related to the engine occur, then it is crucial to do something to solve this. The best thing that you can do is go over to a skilled service technician and share your issue with them so that they can find a solution.

– Replacing the Chain

The second method to try to fix a bad timing chain is to replace the old chain with a newer one. However, it will cost some money to purchase a new timing chain for your vehicle. Nevertheless, it is better only to replace your chain since if you do not replace it in time, you might even have to rebuild or replace your entire engine. If the chain fails, it is even possible that you will have to get a new car.

The cost of replacement can differ accordingly, and there is no specific price. The disparity is based on the labor cost. Regarding the replacement, the cost depends on how easily the engine can access it.

It is also essential to know how complex the timing chain is. Once you get the answer to both of these, you can figure out the amount you will be paying. The average price that you will have to pay for the labor cost will be around $400 to $1,000.

For the parts, the cost will be almost 200 to 600 dollars. The overall price you will have to pay will be around 1,000 to 1,600 dollars. If you get the work done from your local dealer, you will find it much more expensive.

In that case, it is best to go to a local repair shop where you will be charged a lesser amount. The mentioned costs will cover the replacement of the timing chain. However, it will not cover the cost of the damage that will be caused to your vehicle’s engine, so you will have to see that for yourself.

– Replacing It Yourself

When it comes to fixing a timing chain via replacement, you can replace it yourself. However, if you are not a skilled or professional mechanic, you should not try to replace it. You need a lot of experience to do this and all of the required tools if you want to replace it on your own.

It is best to get this work done by someone who works at a shop. This is because they are doing these types of things all day and have experience doing this job.

How Can You Know the Symptoms of a Bad Timing Chain?

You can know the symptoms of a bad timing chain when stretching causes problems. Other symptoms could be worn-out tensioners or sprockets, noisy chain guides, or if you are having issues with the engine light. You should also check for direct damage or the chain slipping from a sprocket.

– Issues Due To Stretching

When the timing chain begins to wear out, it will stretch itself. It will only extend when you have kept it with you for a long time. The correct valve timing will degrade as well.

Once this happens, it will increase the vehicle’s fuel intake. The power will also reduce itself to much lower engine speeds, and the roughness will increase simultaneously. It is imperative to remember that once the chain stretches, it will make a weird noise.

The sound will be like a rattling or a jangling sound. You will be able to hear this sound when the hood is open, and as the engine speed changes, the sound will change simultaneously. The sound will be connected to the movement of the engine.

– Sprockets and Tensioners That Are Worn

This issue will show the same indications as when the chain is stretched. In addition, tensioner bearings and idlers can get worn out easily. They can make buzzing sounds out of nowhere when they get worn out. The sounds will only come when the engine is being operated.

It is important to remember that as the engine’s speed increases, the sound will get louder as well. This is one of the signs that you have a bad timing chain with you. In this case, replacing your chain with a newer one will be best.

– Old and Noisy Chain Guides

During the chain operation, you might have to bear with the noise from the old chain. The chain may rattle when the speed of the engine is slower. If it does not rattle, it will most likely clatter. This will show that the chain is old and cannot be used anymore.

– Chain Slipping From a Designated Sprocket

When you have a bad timing chain, you can get to know it if it seems to be slipping from its designated sprocket. You will notice that as soon as a timing chain hops out of any of its sprockets, the engine will automatically stop running. The vehicle will not move any longer.

As soon as this happens, you might hear a loud clattering sound right before the engine stops. If there is no clattering sound, you will hear a brash grinding sound instead. These sounds will indicate that the engine is about to stop.

– Being Visibly Broken

If the chain is broken, then it can be harmful. This will have the same problems as when the chain comes out of its sprockets. When the chain is broken, it can cause the engine to fail badly, just as written before. It is possible that the machine only manages to work again if it has been set up appropriately again.

– Issues With Engine Light

You could have a broken timing chain when there are issues related to your vehicle’s engine light. When the valve timing exceeds a specific limit you have set, it can cause the Check Engine Light, also known as CEL, to turn on at once. On the other hand, if the exhaust radiations somehow go out of the ordinary, it may result in the same thing happening.

Once you notice a CEL warning, you must quickly act before the problem increases. It is best to go to a technician with experience to solve this. You can expect your problem to end in no time, and your engine will work properly.

On the other hand, ignoring the warning of the CEL can cause a lot of damage to your engine. Furthermore, it will also severely damage the other systems related to your vehicle’s engine. It is important to remember that this warning will only appear for some of the automobiles when their timing chain fails and not for all issues.

How Can You Know the Causes of Your Broken Timing Chain?

You can know the causes of your broken timing chain if a tensioner has been tightened or if the engine is worn out. Your timing chain could also fail when there is no consistency in keeping the engine oil clean and well-maintained.

– Tight Adjustment of a Tensioner

The timing chain could have broken due to the tightness adjustment of a tensioner. When the timing chain has its tensioner that can be adjusted, it could have been set to quite tightly. If the chain has been tightened more than necessary, it will ruin the structure of the chain and damage it in many more ways.

It would wear out the guides and the sprockets of the timing chain. Once the chain wears in this way, it will cause the entire chain to break at last.

– Worn Out Engine

It could be because the engine is worn out. When a vehicle gets older, all the components of the car get weaker, and this causes the chain to break eventually. At this point, the sprockets and the guides also get worn out. It is also important to remember not to drive your vehicle at its max speed daily.

When you do this, it causes the timing chain to get extremely hot at once. It causes the chain, guides, and sprockets to wear out while they receive the intense heat. This can cause the chain to break very quickly and effortlessly. It is best to drive your vehicle at an average speed, as it will also prevent you from being injured or getting in an accident.

– Failure To Maintain and Filter Engine Oil

Your chain could be broken when there is a failure to maintain and filter engine oil. These two things can affect the lifespan of your timing chain highly. When there is polluted engine oil, it can cause damage to the chain faster than usual. It also damages the sprockets and the guides.

This damage could make the entire timing chain break altogether. To keep your chain lasting long, you must provide your vehicle with regular care. To take care of it appropriately, you will have to ask for help from your vehicle’s manufacturer.

It is important to remember that this will also give your entire engine a long life. In this case, there will only be two things that will provide you with great benefits. These two things will be the periodic oil changes and the filter changes that will take place.

Conclusion

It is imperative to remember that you will need some mechanical experience and expertise to replace a faulty timing chain on your own and that you should go to a professional immediately if that is not the case.
