When repairs alone can no longer save a failing engine, drivers are faced with a tough decision about how to proceed: should they go for an engine rebuild, or an engine replacement?
What Is An Engine Rebuild?
An engine rebuild is the process of having your engine broken down into its many parts, and replacing any damaged or worn components with new ones. Once reassembled, the “rebuilt engine” is often like-new.
What Is An Engine Replacement?
Engine replacement is when an engine is so damaged that it cannot be rebuilt, and must instead be completely replaced. This process results in a completely new engine replacing your old one.
Signs That Your Engine Needs To Be Rebuilt or Replaced
If you’ve noticed any of the following symptoms, they may be signs that your engine has suffered significant damage and could be in need of a rebuild or replacement:
- The Check Engine Light is On – although the “check engine” light has become something of a running joke over the years, it’s important to remember that it actually serves an important purpose, and can be your first indication that something is amiss with your engine.
- Loud and Unusual Noises – if you hear loud knocking or rattling sounds coming from your vehicle, it is very likely that it’s being caused by damage to the engine or its components, such as worn-out bearings and broken piston rings.
- Loss of Power – failing to start or reliably maintain power are major indications that your engine is in a state of disrepair and in critical need of replacement.
- Increased Fuel Consumption – if your vehicle is consuming fuel at an unusually high rate, it may be a sign that your engine is getting old and needs to be replaced. The older an engine gets, the less efficiency it has, so be sure to take note of any gas mileage discrepancies.
- Abnormally Smoky or Colorful Exhaust – if you notice a significant increase in the amount of smoke coming from your exhaust, or a change in its coloration, it could be an indication of an aging engine in need of replacement.
- Metal Shavings – if you find metal shavings in your vehicle’s oil, it strongly suggests that your engine’s parts are so severely worn down that failure is practically inevitable.
- Notable Oil Consumption – if your vehicle is consuming oil at an abnormal rate, it may be a sign that your engine needs a rebuild, as worn piston rings could be to blame.
- Low Engine Compression – misfires, low gas mileage and general loss of power are all signs of low engine compression, which itself is a sign of considerable engine wear.
Be aware that, while these symptoms do not necessarily confirm the need for an engine rebuild or replacement, their presence does indicate that a mechanical issue of some kind is brewing.
Engine Replacement vs. Engine Rebuild
The choice between getting an engine rebuild or an engine replacement mainly comes down to the scope and severity of your current engine’s damage level, and the costs associated with each service.
What Are The Benefits of An Engine Rebuild?
- It’s Usually Cheaper Than An Engine Replacement – although mileage may vary depending on the situation or necessary parts, it’s usually cheaper to rebuild an engine than replace it. Be aware that this is not a guarantee, however.
- It’s Better For The Environment – a rebuilt engine requires far less resources to produce than a replacement engine or a new car, taking less of a toll on the earth.
- Better Fuel Economy and Performance – with new, freshly replaced parts, a rebuilt engine is bound to have far better fuel economy and performance than before.
What Are The Benefits of Engine Replacement?
- It Can Be Cheaper Than An Engine Rebuild or Repair – sometimes the cost for repairs or rebuilds can be just as expensive as an engine replacement, if not more so. Replacements can save money in the long run, too, as they usually won’t need expensive maintenance or repairs for quite a while, letting you hold onto money that would have otherwise been spent on replacement parts.
- It’s Much Cheaper Than A New Car – when compared to buying a new car, engine replacement is a vastly cheaper option. Better yet, the engine replacement service might be covered by insurance or your vehicle’s warranty!
- It’s Just as Reliable as a New or Rebuilt Engine – a replaced engine is a new engine. With proper maintenance and care, it has a long life ahead of it. If your vehicle’s major issues are mostly limited to its engine, why buy a whole new car when an engine replacement will be just as effective?
