- Final Conclusion
- Frequently Asked Questions (FAQs)
If your mechanic told you that you need an engine rebuild or replacement, you probably already have an estimate. Now you’re looking to verify whether the cost is worth it, or your mechanic is trying to scam you. You’re probably looking for other options as well.
An engine replacement or rebuild is necessary when certain internal parts in your engine have failed. Whether it’s the head gasket, the pistons, or one of the bearings within your engine. In any case, when you see certain symptoms, you will need a new engine. We’ll discuss more about the symptoms later on.
For now, you’re probably wondering how much does an engine replacement cost? Well, when it comes to an engine replacement, you typically have three options: rebuild, used replacement, or remanufactured replacement. They are all costly options but one may be better than the other for you. Here’s the difference:
Engine Rebuild Cost
An engine rebuild is a process that involves removing the engine, taking it apart, and replacing all the necessary parts so that it will function like new. Your mechanic will then reassemble the engine and put it back in the car. The process requires machining and finishing repairs, if necessary. Your mechanic will keep the original engine block but will replace a lot of your engine parts.
This process will typically cost around $2,500 to $4,500, and it will vary depending on your car’s make and model. Needless to say, cars with bigger engines such as sports cars and luxury cars will likely cost more.
A much cheaper option would be to buy used engines instead of rebuilding them. You can find used engines on eBay or your local junkyards. These used engines can come from either a user who no longer needs the original engine because they replaced it with a new one, often for performance gains.
Or from junkyards that were scrapping a car but took the engine out to resell (just like the Honda catalytic converter scrap prices and the free catalytic converter scrap price guide, as well as the Mini Cooper catalytic converter scrap value and the Chevy Equinox catalytic converter scrap price).
The prices will vary depending on where you find them and the engine’s age, mileage, and condition. Used engines are also often sold as either a short block or a long block. A long block engine means it’s a complete engine that you’re likely able to simply fit in your car.
A short block engine means only the lower section of the engine is included, this includes the engine block, crankshaft, connecting rods, pistons, bearings, and oil pan. A short-block engine is likely cheaper, but you will still need to find and pay for parts you don’t get, such as the head gasket, valves, and a few others.
A used engine can be as cheap as $600, but keep in mind an engine this cheap might not be in good condition. Additionally, you will still need to pay for the labor cost of installing the engine. All in all, a decent used engine will cost you around $1,500 to $3,000. If a Northstar engine fits your car, consider one of those.
As the name suggests, a remanufactured engine means that the engine has been pulled out from a vehicle and returned to factory conditions. Or at least, as close as possible to factory conditions and specifications. Simply put, a remanufactured engine has been restored to perform as if it had just come out of the factory.
The process involves machining the engine’s cylinders along with all other parts and replacing the necessary parts with OEM products. This restores them to their original specifications. A remanufactured engine is probably your best bet for an engine replacement.
The engine will perform like brand new, and remanufactured engines often come with a warranty for peace of mind. However, they can cost anywhere between $2,500 to $5,000 depending on your vehicle’s make and model. So, while it is a quality option and a safe bet, it will put a significant dent in your bank account.
The remanufacturing job is usually done by an auto shop or auto repair company that has gotten its hands on the original blueprint of an engine. One such company is JASPER Engines & Transmissions.
All three options are going to cost a significant amount of money, and they all have their upsides and downsides. We’ll give you a guide on which one to go for when replacing an engine. For now, let’s discuss the signs you need an engine replacement:
Signs You Need An Engine Replacement
So, do you really need an engine replacement? Or is your mechanic just playing tricks on you? A total engine failure is a major incident, so even if your car didn’t break down, you’re going to notice some symptoms. We’ll list down the symptoms below. If you see any of these symptoms, then you’re likely going to need an engine replacement or rebuild.
Engine Replacement Cost Symptoms #1: Knocking Noise
A knocking noise from the engine usually sounds like two pieces of metal banging against each other. There’s a variety of things that can cause a knocking noise and it may not be a major issue. These causes include incorrect spark plug gap (if so, take some time to learn how to gap spark plugs), bad ignition timing, too lean fuel-air mixture, and low octane fuel amongst other things.
However, a knocking noise may also come from worn-out rod bearings. The rod connects the pistons to the crankshaft, and the bearings will wear out over time. When it wears out, you will need to replace it and do an engine rebuild. If you hear a knocking noise from the engine, try to rule out the other possibilities. If the knocking noise is still there, you will likely need to replace the rod bearings and do an engine rebuild.
Keep in mind that some knocking noise is harmless. If you hear a knocking noise in the first 15 minutes as the engine warms up, then it’s likely just a piston slap and you don’t really need to worry about it. Some engines make knocking noises when they’re cold due to their design. We wrote a great article about piston slap and knocking noises, you can read about it here.
Causes and Reasons for the Knocking Noise
A knocking noise in the engine compartment can arise from a plethora of reasons:
- Incorrect Spark Plug Gap: A misgapped spark plug can cause pre-ignition or misfires, leading to a knocking sound.
- Bad Ignition Timing: If your ignition timing is off, your engine can combust prematurely, producing the knock.
- Lean Fuel-Air Mixture: An imbalance in the fuel-air mix may lead to improper combustion.
- Low-Octane Fuel: Using fuel of lower octane than recommended can cause the air-fuel mixture in the cylinders to ignite too early.
- Worn-out Rod Bearings: Over time, the bearings connecting the pistons to the crankshaft may wear out, causing a distinctive knock.
Diagnosis and Troubleshooting the Knocking Noise
To determine the cause of the knocking noise:
- Check the Spark Plugs: Inspect them for wear, carbon deposits, or an incorrect gap.
- Ignition Timing: A timing light tool can help determine if ignition timing is the culprit.
- Fuel Quality: Ensure you’re using the correct octane for your vehicle.
- Inspect Bearings: If other diagnoses fail, it might be worth checking the rod bearings. Remember, this requires opening up the engine.
DIY Repairs/Fixes for the Knocking Noise
- Regap Spark Plugs: Use a gapping tool to adjust the gap to specifications.
- Change Fuel Type: If using a low octane, consider switching to a higher one.
- Adjust Timing: With the use of a timing light, one can adjust ignition timing to the recommended setting.
Remember, while these fixes may work temporarily, the underlying issue may need professional attention.
Repair/Replacement Costs for the Knocking Noise
Costs can vary depending on the cause:
- Spark Plugs: $4-$15 per plug (labor can range from $40-$150).
- Adjusting Ignition Timing: Typically, between $40-$60.
- Fuel: Costs vary by region, but using the correct octane can save you more in the long run.
- Rod Bearings and Engine Rebuild: This is more extensive and can run anywhere from $1,500 to $4,000 depending on the vehicle and labor costs.
Always include diagnostic fees which can range from $50-$120. These fees might be waived if you proceed with the repair at the same shop.
Conclusion: While some engine knocks are benign, others can signal a significant issue. Always diagnose the problem early and seek professional advice if unsure. Proper maintenance can prevent such issues, ensuring a longer life for your vehicle.
Engine Replacement Cost Symptoms #2: Excessive Smoke
A gas-powered car will emit colorless smoke that’s usually odorless. As for diesel engines, they will usually emit black smoke with a stronger smell, although modern diesel engines are much cleaner now and the smoke is often colorless most of the time. So when you see excessive smoke coming out of your tailpipe, that’s when you know there’s something wrong with your engine.
If you see thick white smoke coming out of your tailpipe, that means your coolant is leaking into the engine’s cylinder. The coolant is then burnt along with the fuel during the combustion process, resulting in white smoke. If you see blue smoke coming out of your exhaust, that means your engine’s oil is leaking into the cylinders. When oil is burnt along with the fuel and air mixture, your vehicle’s smoke turns blue.
Coolant and oil leak is often caused by a blown head gasket, which is a thin piece of metal that sits between your engine block and cylinder head. The head gasket prevents coolant and oil from leaking into the cylinders, so they can flow through a designated area and keeps the engine cool and lubricated. If the head gasket is blown or cracked, you will need to replace it.
Causes and Reasons for Excessive Smoke
The type of smoke emitted from the tailpipe can be a telltale sign of underlying issues:
- White Smoke: Generally, thick white smoke indicates coolant intrusion into the combustion chamber.
- Blue Smoke: This is a sign that engine oil has made its way into the combustion chamber and is burning off.
- Blown Head Gasket: A pivotal component, the head gasket ensures coolant and oil stay separated from combustion processes. If this gasket fails, it can lead to both coolant and oil leaks inside the engine.
Diagnosis and Troubleshooting Excessive Smoke
Identifying the cause of smoke involves:
- Checking Coolant Levels: A decrease in coolant levels without visible external leaks could indicate an internal leak.
- Oil Level and Quality: Examine the oil dipstick. Milkiness or a creamy brown texture can signal coolant mixing with oil, a sign of a blown head gasket.
- Compression Test: A cylinder compression test can confirm if the head gasket is compromised.
DIY Repairs/Fixes for Excessive Smoke
- Topping Up Fluids: Refill the coolant and oil to their respective levels.
- Sealants: As a temporary measure, there are head gasket sealants available in the market that can plug small leaks. However, this is not a long-term solution.
- Replacing the Head Gasket: This is a challenging task and requires careful disassembly and reassembly of parts of the engine.
Repair/Replacement Costs for Excessive Smoke
Expenses hinge on the root cause:
- Coolant or Oil Top-Up: Typically, coolant costs between $10-$30 per gallon, while engine oil prices range from $20-$50 per 5-quart container.
- Head Gasket Sealants: Temporary sealants can cost around $20-$60.
- Head Gasket Replacement: Depending on the vehicle, a head gasket part may be priced between $40-$250. However, due to the intensive labor involved, costs can surge from $1,000 to $2,500 or more. This price includes labor, parts, and other supplementary charges.
Diagnostic fees might be additional, ranging from $50-$120, but these could be omitted if repairs are conducted at the diagnosing facility.
Conclusion: Recognizing the type and cause of excessive smoke can prevent severe engine damage. Early intervention is paramount to ensure minimal repair expenses and extend engine longevity. Always consult a professional if uncertain about the origin of the problem or how to address it.

Engine Replacement Cost Symptoms #3: Your Car Is Burning Oil Quickly
Most cars will use around 1 quart of oil for every 800 to 1,000 miles. If you notice your engine using more than that, it’s a sign that your engine is burning more oil than it should. This is usually because there’s a leak in your head gasket, and the oil is escaping into the engine’s cylinder. The leak may be small and that’s why you’re not noticing any blue smoke, but there’s still enough leak that your engine is using more oil than it typically would.
Check your oil level once a month, if it drops below the minimum level on the dipstick, refill your oil as necessary. If it quickly drops below the minimum again before the next oil change, then you likely have a head gasket leak. In which case, you will need an engine rebuild.
Causes and Reasons for Burning Oil Quickly
Excessive oil consumption can stem from multiple factors:
- Worn Piston Rings: These seal the cylinder to prevent oil from leaking into it. When worn, they allow oil to seep into the combustion chamber.
- Damaged Valve Seals: Over time, valve seals can degrade, enabling oil to leak into the combustion chamber.
- Leaky Head Gasket: As previously mentioned, a compromised head gasket can allow oil to seep into the engine’s cylinder.
- Poor Quality Oil: Using a lesser quality or incorrect oil grade can lead to increased consumption.
Diagnosis and Troubleshooting Oil Consumption
To pinpoint the issue:
- Regular Oil Checks: Monitor your oil levels consistently. A drastic dip in levels over short intervals is alarming.
- Spark Plug Examination: Oil-soaked spark plugs might signify oil leakage into the combustion chamber.
- Compression Test: A differential compression test can shed light on whether the piston rings or valve seals are compromised.
DIY Repairs/Fixes for Oil Consumption
- Oil Level Maintenance: Ensure you consistently top up your oil to the required level.
- Oil Additives: Certain additives can temporarily reduce oil consumption by rejuvenating seals.
- Switch Oil Grade: Sometimes, a thicker oil can reduce consumption. Ensure it’s compatible with your vehicle.
However, if the issue originates from damaged components like piston rings or valve seals, professional intervention is needed.
Repair/Replacement Costs for Burning Oil Quickly
Prices diverge based on the underlying issue:
- Oil Top-Up: A quart of oil typically ranges from $5-$15, depending on the brand and type.
- Oil Additives: These can cost around $10-$30 per bottle.
- Piston Rings Replacement: The cost of piston rings themselves varies from $40-$200 for a set. But with labor, you’re looking at $1,000 to $3,000.
- Valve Seal Replacement: Parts might be as cheap as $20-$100, but labor can catapult costs to $1,000-$2,500.
- Head Gasket Replacement: As mentioned earlier, the comprehensive cost, including labor, can range from $1,000 to $2,500.
Diagnostic charges apply, averaging $50-$120. Some repair shops might renounce these fees if they conduct the repairs.
Conclusion: While a slight increase in oil consumption over time is anticipated, abrupt or excessive use is a red flag. Maintaining vigilance and conducting regular checks can preempt extensive damage and high repair costs. If there’s any ambiguity, always resort to a trusted mechanic or auto technician for a professional diagnosis and solution.
Engine Replacement Cost Symptoms #4: Engine Misfire And Compression Loss
An engine misfire happens when one more cylinder isn’t firing or igniting at the right time, hence called a misfire. When an engine misfires, you will notice a popping sound and sometimes excessive vibration. You will also experience a lack of power and if it’s severe enough, your vehicle will struggle to accelerate.
Engine misfires are often not serious. If you drive a gasoline vehicle, the problem often stems from a faulty ignition coil, bad spark plugs (which you can diagnose by learning how to test spark plug), and bad ignition timing amongst other causes. If this is the case, you will either need to replace or tune the parts to fix the issue.
Once resolved, your engine should run smoothly. We wrote a great article about engine misfires and how to diagnose them, it should help you resolve the problem and you can read it here (as well as our guide on the Dodge P0300 code).

If you spot signs of overheating, it’s paramount to diagnose the root cause promptly. Doing so can save you from the hefty cost of an engine replacement down the road. Always ensure your cooling system is in tip-top shape; it’s the frontline defense against overheating.
Engine Replacement Cost Symptoms #10: Metallic Particles in Engine Oil
During your regular oil change or inspection, if you notice tiny metallic particles or shavings in the oil, this is an alarming sign. These particles are evidence of internal components wearing against each other. Such friction can cause extensive damage and dramatically reduce the engine’s lifespan.
Conducting regular oil changes and using high-quality engine oil can help minimize wear and tear. However, if you already notice these metallic shavings, consult a mechanic for an in-depth engine analysis.
Understanding the Implication
The presence of metallic particles in engine oil is a significant cause for concern. Essentially, these particles indicate that there’s metal-on-metal contact occurring somewhere within the engine. When engine components start wearing down, these tiny fragments shed and end up circulating with the oil.
Why It’s a Problem
- Accelerated Wear: The metallic particles increase the abrasiveness of the engine oil, leading to even faster wear of engine components.
- Clogging: These particles can block oil passages, leading to reduced lubrication in vital engine parts.
- Engine Failure: Continuous metal-on-metal contact can lead to significant engine failures, as parts degrade without adequate lubrication.
- Bearing Wear: Bearings, designed to reduce friction between moving parts, can shed metal if they start wearing out.
- Cylinder Wall Wear: Over time, the piston’s movement against the cylinder walls can wear them down.
- Valvetrain Wear: The constant opening and closing of valves can lead to wear if not adequately lubricated.
- Transmission Contamination: In some vehicles, especially motorcycles, the transmission and engine share the same oil. Wear in the transmission can introduce metallic shavings into the engine oil.
What to Do Next
- Oil Analysis: Consider getting your oil professionally analyzed. This can give insights into which engine components might be wearing out.
- Magnetic Drain Plug: Use a magnetic oil drain plug. It will attract and hold onto many of the metallic particles, preventing them from circulating.
- Upgrade Your Oil: High-quality engine oils with proper additives can better protect the engine and reduce wear.
- Routine Check: Check oil regularly and look for signs of metal shavings. If found, consult with a mechanic immediately.
- Thorough Engine Inspection: Have a mechanic inspect the engine components, especially if metallic particles are consistently present during oil changes.
Costs and Implications
- Oil Analysis: Typically ranges from $20 to $100.
- Engine Inspection: Depending on the depth of the inspection and your location, this can range from $100 to $400.
- Engine Repairs/Replacement: If significant wear is detected, repair costs can range from a few hundred dollars for minor fixes to several thousand for major overhauls or engine replacements.
Conclusion: The presence of metallic shavings in your engine oil isn’t just a minor inconvenience; it’s a potential warning sign of impending engine troubles. The sooner you address the issue, the more likely you are to prevent severe damage, saving you considerable money and extending the lifespan of your engine. Always opt for regular maintenance to detect and rectify such issues early on.
In conclusion, while engines are built to last, they’re not invincible. Regular maintenance, timely repairs, and being attuned to these signs can prevent the need for an engine replacement. However, if multiple symptoms appear simultaneously or persist, it’s wise to prepare for a potential engine overhaul or replacement.
New Engine Cost
An engine rebuild or replacement costs so much money simply because of how labor-intensive the process is. Even if you decide to replace the engine rather than build it, you will still need to pay for the labor cost of installing the engine into your car. This process will take at least a couple of days to finish, as your mechanic needs to connect the engine to the fuel line, the transmission, and various other components.
If you choose to rebuild it, it’s also expensive because of the labor. Engine parts are often not very expensive, with a few exceptions of course. For example, a new head gasket will cost you no more than $500, and often as little as $200. It’s the process of disassembling your engine and rebuilding it that costs a lot of money. Just to replace the head gasket, here’s what your mechanic will need to do:
- Drain all oil and coolant from your engine.
- Remove a significant portion of your engine, including the camshafts, cylinder heads, and the broken head gasket itself.
- Clean the surface of the engine block and bolt holes.
- Fit in the new head gaskets, the cylinder heads, and everything else that was taken apart before.
- Set the camshafts and timing gears back to your car’s exact orientation, making sure it runs as smoothly as it should.
The steps above are an oversimplification of the real process, and that’s just to replace the head gasket. If you need to replace the pistons, con-rods, bearings, and other internal parts, it’s even more complicated.

How To Rebuild An Engine
Whenever we make replacement or repair articles, we will often recommend our readers to do the job themselves to save some money. We recommend this when it’s a simpler job like changing your oil, replacing old spark plugs, or even cleaning catalytic converters. They’re relatively simple, don’t require specialized tools, and will take a few hours at most.
However, rebuilding or replacing an entire engine is a much more complicated job and we will never recommend anyone to do it themself unless they’re a trained mechanic with access to the necessary tools. Not to mention, an engine rebuild or replacement can take anywhere between 15 to 25 hours to finish. We’re sure your time is much too valuable to spend on rebuilding an engine.
Additionally, rebuilding or replacing an engine requires precision. One wrong step during assembly and your car may not even start, let alone run properly. Bottom line: It’s not worth rebuilding an engine on your own even if you save a lot of money.
How Much Does It Cost To Replace An Engine
So, you need an engine replacement and it’s very costly, is it worth it? Before you give your mechanic the go-ahead in replacing or rebuilding your engine, take a look at your vehicle’s market value.
If the vehicle’s resell value is significantly higher than the engine replacement cost, then we would recommend going ahead with the replacement job. But if it’s not that much more valuable, you might be better off selling the car as-is. Even if it means selling it at a lower price.
For example, if an engine replacement for your vehicle costs $4,000 and your vehicle can be sold for $10,000, then we would recommend that you go ahead with the replacement job. However, if your car is only worth $5,000 on the secondhand market, then maybe it’s best to sell it as-is.
Afterward, use the money to buy a new car instead. As mentioned, you will need to sell it at a lower price, but this will at least put cash on your hands, rather than having to put out cash for an engine replacement.
Selling Your Car As-Is
If you’re selling your car as-is, then you have two options: sell it under market value or scrap it. The first option will still tend to give you more money, but it might be hard to find a buyer who’s willing to buy a broken car even if it’s under market value. This is because they will still need to deal with the process of fixing the problem and paying for it.
The second best option is to scrap the car. There are two ways to do this, either you take the car to a junkyard and they will give you the car’s scrap metal value (just like the Scion TC catalytic converter scrap price). Or, the more complicated option but will likely put more money in your hand, is to take your car apart on your own and sell the parts and accessories.
The second option will require you to take apart and salvage parts like the interior trim, suspension, engine parts, and maybe even body panels. And then selling them to people who drive the same vehicle as you do. This will take some time and skill to do, but the individual parts will be worth more and you might be able to earn more cash. Of course, if taking apart a car and salvaging parts doesn’t sound like a fun activity to you, then we recommend just selling it to a junkyard instead.
Of course, for some people, a car is more than just a mode of transport, cars often have sentimental values. Maybe you got married in your current car, or maybe it’s been in the family for generations, or maybe you just have tons of memories with it. In this case, we understand if you want to keep it and go ahead with the engine replacement. In which case, here’s our advice:
Engine Replacement Cost: Rebuild, Used, Or Remanufactured
So, rebuild, used, or remanufactured? We generally won’t recommend buying used engines, since they’re often of lower quality and don’t come with a warranty. Unless you’re sure that the engine is in good condition, or you don’t have any other options financially, and you’re adamant about replacing the engine in your car instead of selling it, then you shouldn’t buy used engines.
How about rebuild vs remanufactured? Well, this comes down to two things: how much do you trust the auto shop that’s doing the replacement or rebuild? And what fits your budget better? An engine rebuild might not be advisable if you don’t fully trust the auto shop.
They might do a shoddy job and you might still be left with a troublesome engine even after the rebuild. Remanufactured is often more recommended. They are more expensive, but the engine has been restored to factory specifications and should work smoothly. If you can find one that fits your budget, then remanufactured engines are the way to go.
Either way, we’d like to remind you that you should go to an auto shop that offers a warranty. If anything goes wrong, you can have it repaired for little to no money at all. Also, ask if they have a courtesy car. An engine replacement job can take up to a week. It would be nice if they could provide you with a courtesy car.
If not, you’d know in advance so you can make arrangements for your daily commute. And finally, remind your mechanic to keep you updated with the repair process. This way, you won’t be surprised by unexpected repair jobs that you didn’t see and approve in the initial estimate.
How Much Is a New Engine for a Car? Facts You Need to Know
Here are the 10 need-to-know knowledge from the article:
- Engine failure can be caused by wear and tear or technical breakdown, and when it happens, the engine should be replaced as soon as possible.
- When deciding whether to replace an old car’s engine, you need to consider the severity of the problem, the cost of repair, and the car’s value to you.
- Swapping out an engine is a challenging task that requires a distinct strategy for replacement, and having a service handbook tailored to your car is crucial.
- Signs of engine trouble include decreased performance, grinding, increased exhaust, leaking fluid, weird noises, low oil levels, engine misfire, and compression loss.
- To determine if your car is worth repairing, check its age, total miles run, current mileage, physical condition, history of repairs, and compare the stats.
- Minor repairs that can be done to increase a car’s performance include changing clogged oil filters and checking for low fluid levels.
- The cost of replacing or repairing an engine may vary depending on the engine type and the type of repair it requires. The average price of engine repairs can vary from $3000 to $4500.
- The price for new engines starts at approximately $4,000 for a 4-cylinder, $6000 for a V6, and $7,000 for a V8, and prices may increase based on the engine’s complexity and the car’s brand.
- Hybrid car engine repair cost depends on whether the electric motor or gasoline engine needs to be replaced, and it can cost between $2,000 and $3,000 to replace the gasoline engine and $6,000 to $9,000 to replace the electric motor.
- Options for engine replacement include engine rebuild, used replacement, or remanufactured replacement. Engine rebuild costs between $2500 to $5000, used engines can be bought for as cheap as $600, and remanufactured engines cost anywhere between $2500 to $5000.
Engine Replacement Cost: In Conclusion…
An engine rebuild or replacement is an expensive repair job. But like it or not, you will eventually need to do it if you drive a high-mileage car. Replacing your engine with a used engine from a scrapyard is a much cheaper option. But you need to make sure that the engine is in good condition before buying it. Otherwise, you’re going to be stuck with a troublesome engine anyway.
An engine rebuild is generally the better option. You’re replacing just the necessary parts in your current engine, but it will still make your engine run smoothly and almost like new. We recommend doing this as long as you trust the repair shop will do a good job and won’t charge you for any unnecessary repairs.
Lastly, remanufactured engines are often the best choice. These engines have been restored to factory specifications and will run just like when they rolled off the assembly line. It’s usually much more expensive, but it’s like getting a new engine. They also often come with a warranty so you won’t have to worry about expensive repairs anytime soon.
If all of the options above are too expensive and don’t make sense financially, your last option would be to sell your car as-is. As mentioned, you will have to sell it at a lower price, but it will at least put some cash in your hands. Maybe it’s time you finally put a down payment on that dream car of yours.
Frequently Asked Questions
If you’re still curious to know more about an engine replacement cost, our FAQs here might have the answers…
How Much Does It Cost To Rebuild An Engine
If your existing engine, with whatever issues it may have, isn’t able to be repaired, then you typically have several options. You’d either replace the entire engine or have it rebuilt, instead. Rebuilding an engine is the middle ground between replacing your engine with a used motor, which tends to be far cheaper, albeit with some questionable build quality. Or, having your engine replaced with a remanufactured motor, which guarantees much better quality than used engines, but elevates an engine replacement cost even higher, as well. Meanwhile, with an engine rebuild, you’re simply taking your existing engine. Then, keeping all the good parts, and swapping out all the bad ones. With some simple reconditioning work added on top, you’d usually spend between $2,500 to $4,500 on an engine rebuild.
How Much Does A New Engine Cost
Should you need to buy a brand new engine for your car, the engine replacement cost will vary depending on the condition of the engine. On the bottom end of the scale, there are plenty of used engines that have been scrapped from junkyards or auctioned off by folks online which you can pick and choose from. You can sometimes find used engines for as little as just $600. Albeit used engines this cheap will be of questionable quality. If you want the guarantee of a higher-end product that’ll work reliably from the get-go, you could instead buy remanufactured engines. These are basically used engines but have been carefully reconditioned to meet (or sometimes exceed) the original OEM standards. Remanufactured engines can even come with a warranty, which is what you get when you pay $2,500 to $5,000 for a new motor.
What Engines Are Compatible With My Car
If you’d rather undertake something more interesting with your engine replacement cost budget, you might even consider an engine swap. This is where you essentially replace the original engine of your car with an engine from another vehicle. It’s a fun passion project for many, although it’s no doubt more complicated and best-reserved for enthusiasts. For example, fitting a muscle car engine into an economy car isn’t at all easy. The key stumbling block for engine swaps is figuring out whether the to-be swapped engine could even fit inside your existing engine bay. This is where you’ll have to dive deep into forums or Google for engine compatibility charts to figure out whether an engine is or isn’t suitable. It’s best to look at forums and online chatter to learn from the experiences of those who’ve tried something similar before.
How Much Does An Engine Swap Cost
Speaking of engine swaps, there’s also the matter of the engine replacement cost. The actual cost of swapping an engine into your car will vary wildly depending on what engine it is. Or, if there are any other modifications that you have to make. As well as, the engine’s condition and specifications, among others. Ordinarily, the budget for an engine swap can vary between $2,000 to upwards of $8,000. If you’re swapping in a more commonly-used engine that’s in okay-ish condition, you’ll tread closer to the $2,000 mark. However, if you intend on swapping in a rare, high-spec engine that’s in perfect condition, you’ll likely have to spend close to five digits. Astoundingly, it’s pretty common to see folks spending $20,000 or higher on an engine swap if serious modifications and tuning are needed.
How Much Does A Mechanic Charge Per Hour
The average hourly rate of mechanics here in the US differs by quite a bit. It’s a large country with diverse socio-economics, so certain regions might see you pay more than others in labor charges. For example, a workshop in an urban setting would no doubt cost more than a workshop in rural areas. Other factors include the type of workshop that you’re visiting. Is it a small mom-and-pop shop or is it part of a big-name dealership? Plus, the make and model of your vehicle may also determine the labor costs. If your car is tough to work on that requires more effort and time, you can bet that it’ll raise the labor rates, too. On average, the hourly labor charge for across all mechanics in the US ranges from $75 per hour to $130 per hour.
