Your vehicle’s engine works hard for you, and over time, all that hard work can wear it down. Eventually, your engine might degrade to where it needs a rebuild, especially if it has not kept up with regular maintenance or oil changes.
If you suspect your engine is damaged or in need of a rebuild, make it a priority to have it evaluated by our professionals before it’s too late. Our mechanics will quickly and accurately assess any suspected issues with your engine, and come up with a game plan to help it get back to its former self, including our engine rebuilding service.
Signs That You Might Need To Rebuild The Engine
If you are experiencing any of the following issues, it may be evidence that your engine has suffered serious wear and needs a rebuild:
- Loud Knocking Sounds – loud knocking sounds show worn bearings, which can lead to the damage or destruction of your engine if not dealt with promptly.
- 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.
- Smoky Exhaust – a significant presence of (typically white) smoke in the exhaust is another sign of worn piston rings. Smoky exhaust, when coupled with increased oil consumption, is one of the most common indicators that your engine needs a rebuild.
- Metal Shavings – if you find what appear to be metal shavings in your vehicle’s oil, it likely means that your engine’s bearings seriously need replacement.
- 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.
Why Do I Need An Engine Rebuild?
The need (and underlying reason) for an engine rebuild is usually tied to two specific causes:
- Worn Engine Bearings – your engine’s rods, pistons, and other moving parts are all mounted on lubricated bearings. These bearings wear down over time and will eventually need to be replaced, or you risk the total loss of your engine.
- Worn or Improperly Seated Piston Rings – Piston rings are used to create a seal between a piston and cylinder, locking in the gas generated by burning gasoline, and they also have a part in regulating oil consumption. As they wear down, you may experience “blow-by,” which is when oil leaks from the rings and burns up with the fuel in the cylinder, generating the excess smoke that is emblematic of the issue.
Engine Rebuild vs. Engine Replacement
The choice between getting an engine rebuild or an engine replacement can depend on several factors, such as cost, but in terms of necessity, it mainly comes down to the scope and severity of the engine’s damage. If the damage is minor or relatively contained, a rebuild could very well be your best option. However, if your engine has severe damage, such as cracks or openings, it’s unlikely a rebuild will be sufficient, and a replacement might be your only choice.
How Expensive is an Engine Rebuild?
Rebuilding an engine is a considerable investment that can range widely in cost, depending on several variables. Factors like the type of engine, the extent of the damage, and more all play a role in the final cost. As of 2023, a basic rebuild where the engine is simply refurbished can cost, on average, between $2,500 to $4,500. However, a more complex rebuild involving extensive damage or high-performance enhancements may escalate costs up to $6,000 to $10,000 or more.
What About an Engine Repair?
Although engine repairs are often the cheapest option, this only applies to situations where the required repairs are relatively minor. This includes replacing certain parts or components, but the cost itself will vary on what actually needs to be done.
What Causes Engine Damage?
Engine damage can significantly impact your vehicle’s performance and may require comprehensive services like engine rebuilding. Recognizing the common causes of engine damage is crucial for timely interventions and maintenance. Here are the primary factors:
- Inadequate Lubrication: Failure to maintain oil levels and regular oil changes can lead to increased friction and wear in the engine components.
- Cooling System Failures: Overheating due to coolant leaks, malfunctioning water pumps, or blocked radiators can cause severe engine damage.
- Fuel System Issues: Using substandard fuel, or issues with fuel injectors and pumps, can lead to improper combustion and engine harm.
- Ignored Maintenance Signals: Overlooking maintenance alerts or warning lights on your dashboard can escalate minor issues into major engine damage.
- Worn Out Timing Belts or Chains: These critical components, if not replaced as recommended, can fail and cause significant internal engine damage.
- Engine Detonation or Knocking: This can occur from improper ignition timing or using lower octane fuel than recommended, leading to damage.
- Faulty Spark Plugs: Worn or dirty spark plugs can cause misfires, poor fuel economy, and increased emissions, potentially damaging the engine.
Being vigilant about these factors can help keep your engine’s health in check, hopefully preventing the need for extensive services like engine rebuilding.
Does an Engine Rebuild Affect My Car’s Resale Value?
An engine rebuild can affect your car’s resale value, but its impact depends on several factors. Generally, if the rebuild is done professionally and the rest of the car is in good condition, it can maintain or potentially increase the car’s value. This is because a rebuilt engine can extend the vehicle’s lifespan and reassure potential buyers that major mechanical issues have been addressed. However, not all buyers view rebuilt engines positively; some may question the quality of the work and prefer a car with its original, unmolested engine. Therefore, while an engine rebuild can help preserve your car’s value, it might not necessarily increase it significantly in all cases.
Consider Bringing Your Car in For Engine Maintenance
Even if you don’t see any obvious signs of engine problems, having a professional mechanic perform a routine inspection is a good habit. Some people have their vehicles checked once or twice a year like clockwork, whereas others will schedule to have service done after a few thousand miles. Either way, getting into a regular maintenance routine is one of the best ways to ensure the longevity of your engine.
