Therefore, understanding what options you have available to you is the first step to determining what exactly you need to do if your car’s engine block gets cracked.

This article will highlight the main causes of a cracked engine block and provide you with some solutions and diagnostics. We also provide a final resort if there are better solutions than repair options.

What is a cracked engine block?

Before we dig into the details to help you answer the question of what to do if your car's engine block gets cracked, you need to understand what it means when it gets cracked.


As you might already know, your engine is one of the most critical components in your vehicle that you have to maintain all the time. This engine has a block that sits inside it. The engine housing contains several components, like the crankshaft, the cylinders, and other minor and major components.

The engine housing or block is typically made from a durable material that resists extreme conditions like very hot temperatures and others. While the engine block is typically made from strong material like aluminum, it's not expected to last forever, and there will be a point when it might fail because of external reasons.

That's why one of the common questions we receive from our readers is what to do if your car's engine block gets cracked.

What are the main causes of a cracked engine?

While you might expect that your engine block could get cracked over time because of age, some external reasons could fasten the process and make it happen prematurely. According to automotive experts, these are the most common reasons for a premature cracked engine block:

  1. Overheating issues

One of the most common reasons for a cracked engine block is when you have consistent overheating. Therefore, we always recommend our readers keep an eye on the engine temperature and keep up with where the engine temperature is at most the maximum threshold. If the temperature exceeds that threshold, you can easily deal with vehicle self-destruction, not only engine block cracks.

Think about it this way; the engine block serves as the housing of the internal components. Suppose the internal components making up the engine are getting very hot all the time. In that case, the external housing cannot withstand this temperature, and it might get weaker over time, and therefore it could easily get cracked.

  1. Reduction in the coolant

There is another thing relevant to the engine overheating problem that has to do with the cooling system. The cooling system drops the engine temperature when it exceeds the maximum threshold. The cooling system contains an important fluid which is referred to as the coolant. This fluid must maintain at a specific quantity and quality.

There are many reasons why your vehicle might lose coolant, and if this happens, you can easily get engine overheating, which could eventually result in engine block cracking.

In other words, if the engine continues to get hot and doesn’t receive the required cooling from the cooling system due to insufficient coolant level, you can easily get to a point where you wonder what to do if your car's engine block gets cracked.

  1. Reduction in oil pressure

Your combustion system in the engine relies on the cooling system to cool down. There's another system responsible for maintaining the temperature and preventing overheating over time. This system is referred to as the lubrication system.

No specific components make up the lubrication system, and the oil runs around the engine. Every motor should receive a specific level of lubrication through the oil, depending on the oil quality and performance.

You must not drive a vehicle that consumes much oil to the point that your vehicle complains. In other words, if you see a warning light on the dashboard saying that your engine doesn't have enough oil pressure, you could easily lead to a situation where your engine block might get cracked because of overheating issues.

  1. Troubles due to engine misfiring

Finally, if your engine suffers from continuous misfiring, it's not a one-time thing; you can easily deal with a cracked engine block that causes your vehicle to lose its value. Therefore, whenever you notice any signs of misfiring, you have to discuss them with your mechanic and understand what needs to be done.

How To Tell If Your Car Has a Bad Engine

What to do if your car's engine block gets cracked?

If you get to a point where you feel that your engine block is cracked and you confirm that the previous symptoms are continuous, you have to discuss with your mechanic and determine what's the best solution for you.

The good news is that automotive experts were able to put together a list of options for those looking for what to do if their car's engine block gets cracked. Here's what needs to be done in order:

  1. Fix the cracked engine block

The first and most obvious solution for you to deal with a cracked engine block is to fix the problem. However, there are many situations where the crack could be minor where your mechanic could resolve the issue without needing to install major components and without spending so much effort.

However, this does not guarantee that your vehicle’s crack might not evolve. Typically, if the engine block starts to deal with cracks, these cracks can build up easily and might get to the point where you can't fix your engine block.

What's more important is to understand the problem causing the engine block to get cracked. In other words, if what you're dealing with has to do with faulty issues in the cooling system, you need to fix them before you deal with the engine block and do any repairs.

  1. Change the engine block

Unfortunately, there will be a situation where someone might suffer from a major engine block crack that needs a full replacement. In that case, repair costs can climb significantly and might get to the point where people cannot afford to fix the problem.

In most scenarios, automotive experts typically recommend evaluating repair costs. First, you need to do the math and determine the total repair cost needed to fix your problem, including any other problems your vehicle suffers.

The total repair cost should not only include the problem repairs, but also it might need to include the typical regular maintenance. So, for example, if your vehicle is due for an oil change, you should consider that, and if it's also due for a tire rotation, that could be included.

Once you have the final number, you must compare it to your vehicle's value. If you realize that the repair costs are approaching 75% of the value of the vehicle, that's when you have to sell your vehicle instead of wasting your time and money trying to get it to work.

  1. Rebuild the engine

Some people might feel that there is still a chance to fix the vehicle without needing to install a major new component. What they're referring to is the engine rebuild process. During this process, the mechanic takes all the parts out of the engine and fixes what needs to be fixed before resembling the engine again.

While there is some money saving out of rebuilding your engine, you need to be aware of a couple of drawbacks. For example, rebuilding the engine does not guarantee that you're not going to see face the same problem very soon. Also, it's small money saving for overall maintenance costs.

Therefore, before moving forward with the route to build and rebuild your engine, you must evaluate repair costs and compare them to the value of your vehicle.

  1. Sell your vehicle

Finally, if you get to the point where you feel that much repair needs to be done and you can't afford it, consider selling your car. While a limited number of people might accept your car with major engine problems, many companies specialize in buying such vehicles.

Can a cracked engine block be fixed?

Of course, it can. As we indicated in this article, you might have options of fixing the problem, rebuilding the engine, which is still considered a fix, or installing a new engine.

The more important question is whether it's worth fixing the cracked engine block. As we mentioned earlier, sometimes repair costs can be very expensive. Before you go this route, you must evaluate to ensure you're making the right decision.

How much does it cost to fix a cracked engine block?

It's hard as hell. But, as we mentioned, if we crack the block problem is unique and depends heavily on the vehicle’s type and condition. For example, some vehicles might be relatively new, and the correct engine block is minor. In that case, repair costs are going to be relatively inexpensive.

But fixing a cracked engine block should typically cost around $1500. To get accurate estimates, you need to consult your mechanic and have them take a closer look at the vehicle to confirm that there are no other issues associated with the cracked engine block.

How do I prevent my engine block from cracking?

One of the first things that you should focus on is to prevent dealing with such a problem in the first place. Therefore, automotive experts provide you with the following recommendations on what you need to do to avoid dealing with a cracked engine block:

  • The first and most critical thing is to keep up with that car maintenance. Whether this maintenance has to do with the cooling system or the vehicle overall. The more you keep up with this maintenance, the less it is to deal with major car problems at the early stages.
  • Consider using a higher-quality oil. The engine oil is one of the critical components that have to do with the temperature, and if it's not of good quality, you might deal with the correct engine block easily.
  • Never run your car on low oil. As we highlighted before, running a vehicle at low oil can kill your car and might result in sudden engine self-destruction.
  • Finally, it's important never to ignore minor problems like those associated with a minor league or reduction in the coolant level. The more you ignore these problems, the easier it is to get involved and cause severe damage to your vehicle, including cracking your engine block.

Final thoughts

Dealing with a cracked engine block is never fun, and one of the very common questions we continuously receive is what to do if your car's engine block gets cracked. The short answer to this question is that it depends. It depends on your vehicle’s situation and the total repair costs.

If you realize that repair costs are getting too much and beyond what you can afford, consider selling this vehicle. Otherwise, engine block problems are still repairable, and you can check with your mechanic to determine the best option for you.
