Is Rebuilding An Engine Worth It

Updated: Sep 10


Are you wondering if it’s time to rebuild your car’s engine? Luckily, engine rebuilding is not something most vehicle owners will need to deal with while they have their vehicle. That being said, there are a few instances where it may be necessary.


While engines are designed to be strong and hold up against day-to-day driving, they aren’t 100% fail-proof. Let’s explore some of the times when engine rebuilding would be worth it along with what an engine replacement estimate in Elgin, IL would likely cost you.


When is an Engine Rebuild Necessary


Rebuilding a car engine is no small task, but there are a few instances when it’s necessary.


Overheated engine: Overheated engines are a common problem among cars, but when left unresolved for too long, they can cause a major issue. If the cooling system can’t regulate the operating temperature of the motor, the metal block can crack. Depending on the size of the crack, the engine may need to be rebuilt.


Running the engine with no oil: This causes friction and heat that can damage the engine. Once the damage reaches a certain point, the engine will need to completely rebuilt to remedy the issue.


Any kind of mechanical malfunction, whether it’s caused by these issues or something other than gas being put in the engine, can ultimately require a complete engine replacement.


Other Sign An Engine Rebuild is Worth It


There may also be other signs that an engine rebuild is necessary, such as:


  • Banging sounds can be a sign the bearings may be failing, which could cause the engine to seize.


  • Metal flakes in the engine oil mean there is metal-on-metal friction happening in the engine. You or your mechanic should inspect it during every oil change.


  • White exhaust could be the result of a worn piston ring allowing oil to drip and be burned with gas. This is a sign that the engine isn’t being properly lubricated and can cause it to seize.


These are just some of the most common signs that your engine may need to be rebuilt, but always consult your mechanic for a definite answer.


Engine Replacement Labor Time & Estimate


An engine rebuild service in Elgin, IL is one of the more costly and time-consuming repairs. While there’s no exact cost regarding engine parts and labor (every mechanic and vehicle is different), you should expect to pay anywhere between $2,500 to $4,500 for a complete rebuild. The final engine replacement estimate ultimately depends on the labor and the parts needed for the rebuild - the more parts needed the more costly it will be.


Similarly, engine replacement labor time is never a set number. Depending on the amount of work and extent of the rebuild, it can take anywhere from a few days to several weeks (possibly months in some extreme cases). An engine rebuild requires a high level of expertise, so it’s important not to rush the process or the accuracy could be compromised.
