Engine problems are very complex, and when your engine comes to a point where you need to rebuild, you have to think twice before underestimating what's going on. You must try catching the problem before it gets to the point where you must rebuild the engine. Otherwise, the repair costs can pile up significantly.

The good news is that automotive experts were able to put together a list of 15 signs that you need a car engine rebuild. If you notice any of these signs, it's important to capture them as early as possible because there might be a chance that you can fix the engine without needing to rebuild it.

This article summarizes the science that you need a car engine rebuild. We encourage you to watch for any of these signs and never underestimate them. Whenever you notice any of them, consult your mechanic immediately and have him inspect the engine and fix it if needed.

15 signs you need a car engine rebuild

The common signs that you need a car engine rebuild might come together, but you might see one or more simultaneously. Let's take a closer look at the 15 signs you need a car engine rebuild:


1.    Decrease engine performance

The first and most critical sign you have to keep an eye on is when you notice that the engine performance is reduced. But, of course, it's not going to happen in one day, and this engine reduction in performance will gradually increase, and you will start noticing it more seriously.

2.    Increase fuel consumption

When your engine is overstressed and close to the point where it needs a rebuild, you'll notice that the vehicle is consuming more fuel than it should. In other words, if you realize that you're going to the gas station more frequently than before, you have to address a serious problem facing your engine.

3.    Increased emissions

Another thing you might notice is that your vehicle is producing more emissions than it should. In other words, different components in your vehicle work together to eliminate any potential emissions that could harm the environment and reduce it as much as possible.

A weak engine might not be able to do the job, and it might produce more emissions that could impact the results of your emission test. Have you ever been to an emission test knowing that your vehicle is in good condition but realizing that the vehicle failed? Check out the engine and see if it needs a rebuild.

4.    Knocking or ticking noises

When the engine suffers from internal problems, it will start showing strange symptoms. The most common one is engine knocking or ticking noises. These noises could be minor, and not everybody might notice them, but they could lead to severe troubles if ignored.

That's why automotive experts always recommend that whenever your vehicle makes any strange noises, especially those related to the engine ticking, do not ignore them and talk to the mechanic as soon as possible.

5.    White smoke

If you're driving your car, you'll notice that it shouldn't produce smoke that has a color. But, of course, if you're driving an old vehicle or starting your car in the early cold morning, you might notice this color, but typically, the color should be obscure.

However, if you feel that your vehicle starts to make white smoke color coming out of the tailpipe, it might indicate a serious problem in your engine. That's why we always say that whatever our behavior vehicles make should be taken seriously and communicated with your mechanic to avoid further complications.

6.    Burning smell

The same principle applies to any smell coming out of your vehicle. So, for example, if you just got into your car and noticed that the vehicle is making some weird burning smell, this could indicate that your vehicle is ready for an engine rebuild.

Remember that the burning smell might be associated with other problems related to the braking system or any other system. Therefore, despite the source of this smell, you should talk to the mechanic and explain to him when exactly you notice this smell happening.

7.    Oil leak

An oil leak is a very serious problem; it can easily damage your engine if it's a major leak. That's why you must keep an eye out for any fluid dripping underneath your vehicle because this could indicate a serious risk facing your vehicle.

An oil leak could happen for various reasons, including those related to a weak engine or weak seals. The seals get weaker as the engine ages, and thus where you might need to perform an engine rebuild.

8.    Low oil pressure

If you have a continuous oil leak or if this oil leak is major, you will immediately notice that the dashboard is complaining, showing a low oil pressure. We always mention to our readers that low oil pressure is a very critical serious problem that could easily lead to engine self-destruction. Therefore, you should always pay attention to a low oil pressure warning light on the dashboard.

9.    Check the engine light

Another important light you have to keep an eye on is the check engine light. Although this general warning light could indicate various problems, it's most likely connected to the engine. In many instances, it could indicate that your vehicle is ready for an engine rebuild.

That's why we always mention that check engine light illuminating is one of the most critical signs you need a car engine rebuild immediately.

10.  Reduced compression

When the engine has a problem or is ready for a rebuild, it will not have the right compression. The weak seals might allow gases to escape or impact the overall pressure on your engine. The engine must operate within a certain range of pressure; when this is not maintained, you could easily deal with significant troubles that might require replacing the engine.

11.  Reduced horsepower

Unsurprisingly, if the engine is weak or if it's toward getting towards the end of its lifetime, it will not provide you with the horsepower you were expecting the time you drove it when you first purchased it.

12.  Increased engine temperature

Another important symptom to watch for is increased engine temperature. Automotive experts always like to warn all drivers of any increase in engine temperature because it could kill your engine. You'll see that the warning sign on the dashboard says that the engine temperature exceeds the maximum threshold.

If you feel that the engine temperature is increasing significantly, stop your car and pull over whenever you can to check on the problem and see if it's something related to the overall engine or something more severe, like trouble in the cooling system.

13.  Lack of engine oil completely

in some instances, many inexperienced drivers might underestimate the complaint that the vehicle needs more oil pressure. In that case, they can easily deal with the situation where the engine doesn't have any oil at all! This horrible situation could damage the engine in a matter of minutes.

14.  Other weird noises

Although most noises that you will face include knocking and ticking noises when the engine needs a rebuild, sometimes you might notice some other noises like rattling or potentially noises that are not normal. If that's the case, talk to the mechanic as soon as possible and have him inspect the engine or any other relevant components that could trigger these noises.

15.  Difficulty starting

Finally, a weak engine beyond repair might cause your vehicle not to start. You could start the car, replace the battery, or perform a jumpstart but still realize that the engine doesn't crank or work. In that case, you might be approaching the time for an engine rebuild.

Final thoughts

Engines are not designed to last forever, and will be a point when you have to replace them or rebuild them if needed. Therefore, you must keep up with your engine maintenance and repair any minor problems as early as possible before you get to points where you're dealing with major engine problems.

However, you might get to a point where your engine might require an engine rebuild, where you have to invest a decent amount of money in performing the repairs and having your vehicle run again. This article summarized the 15 science you need a car engine rebuild, and whenever you notice any of these signs, you have to consult your mechanic and resolve the issue.

If you feel that your vehicle has other problems or if repair costs get to the point where they exceed 75% or more of your vehicle's value, it could be perfect timing for selling this car rather than wasting your time and money.
