Are Engine Rebuilds Worth It

Have you wondered: are engine rebuilds worth it? We look at the benefits of a rebuilt engine and if rebuilt engines are as good as new. 

This article covers the benefits of rebuilding your engine and whether it's cheaper than buying a new one.

Is an Engine Rebuild Worth it?

One of the most essential parts of the car is the engine. The car's engine is able to take burning gas and use it as energy to move the wheels, which helps to propel the car. Without that engine, we would be completely unable to drive to all the essential places we need to go. In order to ensure that our engines function the way that they are designed, regular maintenance is required to be performed.

Even though the engine is very important and we need to ensure that they are in fantastic condition, auto maintenance is something we forget to do regularly. Whenever maintenance is forgotten about and put on the backburner, the car engine will begin to suffer and develop issues. Are Engine Rebuilds Worth It?

Usually, a simple repair can fix the issue at hand, but in other situations, a full engine rebuild may be needed. A lot of people wonder what an engine rebuild means. The engine rebuild process is when a mechanic takes out the entirety of a vehicle's engine and takes it apart.

Inspecting and cleaning each part along the way. At the end of the process, any damaged or malfunctioning parts are replaced with new or refurbished engine parts. A lot of people also wonder whether rebuilt engines are exactly like brand new engines. 

The answer is, in essence, yes. The engine will perform like it is an entirely new engine. Rebuilds are a very onerous form of engine repair, but they are worth it as they are a lot cheaper than engine replacements. 

What Are The Benefits Of A Rebuilt Engine

There are a lot of benefits to purchasing a rebuilt motor rather than paying out for a brand new engine. Firstly, you can guarantee that the engine will meet the Original Equipment Manufacturer (OEM) specifications. Rebuilt engines also cost a huge amount less than brand new engines or buying a brand new vehicle.

In fact, you will find that some newer models are far more expensive than the vehicle that needs its motor replaced in the first place. If you are looking at an older vehicle, then a refurbished or rebuilt engine is the best choice to make.

Honda, Toyota, and Ford are the most recommended options, and their rebuilt and used engines are the most in-demand and popular. Routine maintenance is important for all vehicles and engines, no matter what the make and model may be. What Are The Benefits Of A Rebuilt Engine

Regular maintenance increases the lifespan of an engine, as well as boosting the vehicle's performance values and reliability.

The repair costs will decrease too. Routine factory scheduled maintenance includes fluid changes, oil changes, tire pressure, inspections, brake inspections, tire rotations and balancing, air filter cleaning or replacement, battery maintenance, transmission service, wiper blades, fuel systems, coolant flushes, bulbs, and more. 

What Happens When an Engine is Rebuilt

Rebuilding an engine first involves the removal of the engine from the vehicle so that it can be completely disassembled from what is regularly referred to as 'carb to pan'. This is a description that comes from when engines had carburettors rather than fuel injection systems.

These days the phrase would be 'injector to pan', with the pan being the engine's oil pan. Once the whole engine has been disassembled, inspected and cleaned, all the damaged or malfunctioning parts will be replaced with new or refurbished replacement components.

Any new gaskets, seals, and lubricants that are used in the reassembly process of the rebuilt engine should meet OEM standards. The most common component to be replaced with vehicle engines are the following. O rings, gaskets, seals, bearings, valve springs, timing belt or chain, and the oil pump.

What Happens When an Engine is Rebuilt

Major parts will only ever be replaced if it is completely necessary; this is usually for parts such as pistons, camshafts, and crankshafts. If your engine has suffered severe damage, then the engine block may have to be widened and tapered in order to align the crankshaft main bores.

The cylinders can also need to be bored so they can fit the new pistons. This work is immense and takes time, but eventually, it will allow the engine to work as it should once again. Under common circumstances, there are only two scenarios when the choice is not an option.

  • The engine block has been damaged internally due to a faulty crankshaft or connecting rod.
  • The outside of the engine block has been cracked or "windowed". This happens when an internal component punches a hole in the engine block.

Are Rebuilt Engines Good as New?

This can depend massively on the quality of the mechanic. This is a major factor in the quality of the engine rebuild.

A poor-quality engine rebuild can considerably shorten the lifespan of your engine, so it is important to ensure that you can trust the mechanic who is going to be taking apart your engine.

A rebuilt engine with a trusted and proficient mechanic who uses high-quality parts can add hundreds and hundreds of miles to the lifespan of your engine.

Is Rebuilding an Engine Cheaper than Buying an Engine?

Without a doubt, rebuilding an engine is cheaper than buying a brand new engine. Scheduled overhauls are almost always less expensive too. In some cases, you can save up to half of the cost of a new engine simply by rebuilding instead.

Although, there are some cases where rebuilding is not a worthwhile option. In situations where rebuilding will cost just as much as buying and installing a new engine, your mechanic should be upfront with these costs and let you know which option would be more sensible.

With the information that the mechanic supplies you with, you can make a decision on whether to rebuild, buy a new engine, or buy a whole new vehicle.
