Subaru Engine Rebuild Cost [Full and Partial]
Subaru engines have been known to require frequent replacements in the past. While these problems have been caused by irregular maintenance and expected wear over time, you may want to save money on buying new Subaru engines.
In this case, you may be interested in knowing the costs involved in rebuilding them.
On average, the cost to rebuild a Subaru engine is between $2500 and $4000. The actual block would cost around $1500–$2000, while the labor would run about $2000 based on 20 labor hours at $100 per hour.
If you’re considering rebuilding a Subaru engine instead of buying a new one, read on to learn more about the potential costs involved in this process.
The Cost of Rebuilt Subaru Engines
Depending on your situation, the cost of a rebuilt Subaru engine will be different. If you do the work yourself, you will only have to pay for the parts and maybe to have the cylinder heads fixed.
Taking it to a specialist will also require money spent on installation, but it will usually take less time than a DIY process.
| Process | DIY | Mechanic |
|---|---|---|
| Partial rebuild | $1300 - $2000 | $2300 - $4000 |
| Full rebuild | $2500 - $3000 | $3500 - $6000 |
A partial (usually top-end) rebuild will be easier and cheaper than a full rebuild. If you’re experiencing bottom-end issues, doing a full rebuild would usually be more efficient.
The costs will also pile up depending on the number of elements you will be rebuilding. For your peace of mind, you may choose to go for more than necessary.
The cheapest options for rebuilding Subaru engines are DIY or going to a mechanic.
If you would have to go to a dealership, you should be prepared to spend upwards of $6000 or more. Most of that sum will go into labor costs.
The Process of Rebuilding a Subaru Engine
Once a rebuild is considered necessary, the real work begins. There are numerous parts to the process of rebuilding an engine, and these will be tailored to your vehicle’s specific needs.
Let’s break down some of the essential parts involved in the engine rebuild.
The Removal
The old engine will be removed from the vehicle. Each component will be disassembled and then thoroughly cleaned.
There will then be an inspection of each element to establish how worn they are and whether they can be efficiently reused during the rebuild.
The Machining
During this stage, each part that will go on the engine will be primed to work perfectly with the rest. They will be smoothened, micro-polished, straightened and resurfaced as necessary. Each component will have to be in perfect condition before it goes on the engine.
The Reassembly
At this stage, each component will be installed on the engine. This can include old parts, but new parts will also become part of the process.
Gaskets and seals will usually be new, as will gears, bearings, and the timing belt.
The engine will be fully rebuilt from individual components. This is usually the most time-consuming stage because every part must work in harmony with the others.
Plenty of care must be taken during the reassembly to make sure every aspect can properly carry out its role.
Once the reassembly is finished, the engine testing can begin. This is done before the reinstallation of the engine on the vehicle to make sure that any adjustments can be performed before the final stage.
The checks in this stage will include making sure that the compression is working properly and that each element is doing its job. If there are any issues, corrections will be made.
The Reinstallation
During this last stage, the rebuilt engine will be installed in the vehicle, and all connections will be reimplemented.
Once that is finished, the car will be turned on and usually taken for a test drive to ensure that everything is working optimally and that the rebuilt engine is responding as it should input from the driver.
Can You Rebuild a Subaru Engine by Yourself?
A Subaru engine rebuild should, in most cases, be performed by a specialist. It is a complex process that requires plenty of expertise.
Every part of the engine will have to work perfectly, and specialists will be able to perform this job with the highest level of quality.
If you feel confident that you have enough knowledge to do an engine rebuild by yourself, you can save plenty of money on labor costs. The bulk of the work will therefore fall to you.
The old engine will need to be removed and disassembled, and parts will have to be properly inspected to ensure which are still viable for the rebuild.
You will need to order all other necessary parts, usually from a Subaru dealer.
Other Parts of the DIY Process
You will need to take any parts that require machining over to a shop that offers this service, which may require additional costs.
You will usually have to take at least the engine cylinder heads to a machine shop. There may also be a waiting time for them to be finished.
Once you have your machined parts, you will be able to proceed to the engine reassembly. You should test it before reinstalling it in the vehicle, just like a mechanic would do.
Your experience with this process will differ depending on how big the rebuild job will have to be.
If you only have to change a few components, you’ll be able to do a partial rebuild. Top-end rebuilds are particularly common, but you may still want to go the extra mile and add engine mounts or clutches.
A full engine rebuild will usually be the recommended process if you are experiencing bottom-end engine issues. This will include replacing or rebuilding every part, from the seals to the blocks.
When You Should Consider Rebuilding a Subaru Engine
If you’re not sure whether or not you need to rebuild your Subaru engine, check for the following signs that would indicate it might be necessary:
- You have a cracked engine block because of extreme heat or issues like coolant leaks.
- You’re hearing unusual knock-like noises coming from the engine.
- You’re noticing frequent coolant or oil leaks pooling under your vehicle.
- The smoke coming from your exhaust has a different color than usual.
While other elements in your vehicle can cause these issues, you should get your car checked out by a specialist as soon as you notice them.
The specialist will be able to determine whether your engine needs to be rebuilt or replaced.
How Long Does It Take to Rebuild a Subaru Engine?
The time it takes to rebuild a Subaru engine will depend on various factors. The type of installation will have the biggest impact on the length of the rebuilding process.
If you do it yourself, you will usually take longer than a specialist would in the same situation.
On average, an engine rebuild takes between 30 and 40 hours. This requires having all the necessary parts on hand and no unexpected last-minute problems with some of them.
If you are doing this by yourself, you won’t be able to spend long stints of time on the rebuild. You also won’t be able to deal with unexpected issues as quickly as specialists would.
If you’re rebuilding the engine on your own, expect to invest time as well as money in the process. If you leave the vehicle with specialists, you’ll usually have it back in a few days at most.
Is It Better to Rebuild or Replace?
In terms of costs, rebuilding is always the more beneficial option. Replacing the engine will be quicker, but it will cost much more.
If you have the means to do so, rebuild your Subaru engine when you are advised to get a new one. If you’d like to get some assistance with the DIY rebuild process, you can opt for buying Subaru engine rebuild kits.
Depending on the Subaru model you have and the number of parts you need, you will usually spend between $140 – $600. Another practical option would be to purchase a rebuilt Subaru long block.
A long block engine is an assembled engine that includes cylinder heads. You would only have to install the engine in your vehicle without having to go through the effort of taking it apart and putting it back together.
Depending on your Subaru model, you’ll be able to get a rebuilt Subaru long block for an average price between $5000 – $6000.
What Are the Benefits of a Rebuilt Subaru Engine?
There are many benefits to getting your Subaru engine rebuilt. Here are some of the most popular ones:
- You will get to extend the life of your original engine past what might have seemed like its end. This is a more cost-effective option than a replacement with a new one.
- Your rebuilt Subaru engine will get more mileage out of the vehicle and pollute the environment less.
- The engine will have more life, and more components will be replaced.
- Your vehicle will immediately perform better with the original engine than with a new one. Rebuilding the engine skips over that adjustment period.
FAQs On Subaru Engine Rebuild Cost
Can you Rebuild a Subaru Engine?
Yes, a Subaru engine can be rebuilt. Rebuild refers to the process of disassembling, cleaning, inspecting, and repairing or replacing worn or damaged parts in an engine to restore it to its original specifications and performance.
Rebuilding an engine requires mechanical knowledge, special tools, and a clean workspace.
