8 Warning Signs Your Car Engine May Be Damaged and Needs Replacement

A car engine is the most critical component of a vehicle. When it’s running smoothly, it helps the car owner get where they need to go without any problems. But when something goes wrong with the engine, the car can break down instantly and become a major hassle. Unfortunately, one of the most expensive auto repairs in Longmont is replacing the engine. This repair can cost hundreds to thousands of dollars, depending on the make and model of the car. Thankfully, car owners can recognize the warning signs that indicate the car engine needs replacement. Once the warning signs are noted, car owners can take action before it’s too late. Some common warning signs that indicate a car needs a new engine include the following.

The ‘Check Engine’ Light Is On 

Whenever the check engine light comes on, it’s a sign that something isn’t right with a car’s performance. That doesn’t necessarily mean the car owner needs to replace the entire engine, but it could be indicative of a problem big enough that replacing the old engine is the best option. If a car owner notices that this light is on, they should take their vehicle to a mechanic as soon as possible. The mechanic will help diagnose and fix the issue before it becomes more serious. 

Excessive Oil Consumption 

Every car owner must ensure they perform regular oil changes in Longmont, CO. However, if they constantly have to change or add oil to keep up with what their car consumes, then there could be an issue with its piston rings or valves. These two parts are integral components of an engine, and this type of damage requires a complete replacement of both parts, since repairs aren’t feasible in this situation. So, if there is excessive oil consumption in your vehicle, consider getting a new engine sooner than later.    

High Exhaust Emissions Levels                     

A vehicle’s exhaust emissions levels should remain within certain limits as government regulations define them. If they exceed them significantly, there could be an issue with its catalytic converter or oxygen sensor. These parts of an engine system could require an entire replacement, depending on their condition. Ensure that these are tested regularly so that any issues can be caught early and addressed appropriately before they lead to more significant problems, such as needing an entire engine replacement which can be cumbersome and costly. 

Strange Sounds Coming From the Engine                

Strange noises from under the hood of a car when driving could indicate something isn’t quite right with its powertrain system. This includes all the components related to the internal combustion process (e.g., pistons). Interestingly, an oil change in Longmont could be all that is needed. However, if the oil has been changed and the issues persist, it is more serious. Such issues usually require more than simple repairs. Depending on how severe the issue is, car owners may need to get a new engine to return their vehicle to its optimal performance level. So if a car owner hears any unusual sounds coming from under their hood, it’s best to have a mechanic look into it immediately.

Your Car Has Low Oil Pressure 

Low oil pressure is an indicator of engine failure and needs to be addressed immediately. If a car owner doesn’t address the issue, it can lead to further damage and more costly repairs down the road. Low oil pressure could mean an internal leak, or the oil filter needs to be replaced. Either way, it’s important to get it checked out immediately so you can avoid any major damages in the future. The car owner must ensure that only reliable car services in Longmont work on the vehicle.

Your Engine Is Overheating 

If a car’s temperature gauge reads higher than usual while running, this could indicate serious engine trouble and should not be ignored or taken lightly. An overheated engine means that too much heat has built up in the cylinders, which causes them to expand and possibly even crack over time due to extreme temperatures and pressure levels within the cylinder walls. It’s best to get this checked out sooner rather than later because if left untreated. An overheated engine could cause catastrophic damage to other parts of the vehicle and require an extensive system replacement, which could be costly and time consuming.

Loss of Engine Power

If a car owner notices that their car feels different to drive or there’s a slight delay after they press the accelerator, there could be a problem with the car engine. Also, if the car sounds rough when idling or it isn’t revving as it used to, this could be a sign of a serious engine problem.

Oil or Fluid Under the Car

If a patch of oil or fluid is spotted beneath the car when it is parked, it could indicate an underlying engine problem, such as an antifreeze,  oil, or coolant leak. Car owners should report any leaks to  a mechanic who can diagnose and fix the problem immediately.


A well-maintained car should run smoothly and efficiently without any major issues. Little things such as regularly putting water in the car’s radiator, oil changes, and alignment in Longmont can help sustain the car’s engine. Unfortunately, things don’t always go as planned, especially when it comes to automobiles. There are times when the engine might develop some complex fault that requires repair. If the car owner recognizes that the car is faulty early enough, they can prevent serious damage to the engine. To ensure that a car stays reliable and roadworthy for years, car owners should always pay close attention to the warning signs listed above.
