Why Rebuilding Your Engine is Better than Replacing It?


Ever faced confusion figuring out what the issue with your car is - is it the ignition, brakes or engine?

Anyone who owns a car has been there, done that!

In fact, it might get tough at times, especially when it comes to engine issues.

However, what’s more difficult is taking the right measures to have it fixed.

Basically, you have two options - rebuilding your engine or replacing it.

But before we dive into the facts, here’s what one of AG Customs’ satisfied customers had to say about engine rebuilding, “Rebuilding my damaged engine saved me more money and enhanced my engine’s efficiency. I couldn’t be more grateful to AG Customs for recommending this alternative to replacing the engine of my 4-year old SUV, which I must say gives better mileage now.

Why Not to Consider Replacing Your Vehicle’s Engine?

When you opt for an engine replacement, everything from gaskets, bearings, to seals are replaced.

This means that you will have to pay for each of these components and the complete engine, apart from the installation and labor costs.

If you’ve ever been confused about repairing or buying a new car, then you should know that investing in rebuilding your engine is probably better than investing in a new car. 

Repowering your engine with a rebuild costs as less as 10% to 20% the cost of a new vehicle. 

Moreover, you can also save significantly on annual insurance costs on an old vehicle than a new one.

When is the Right Time to Rebuild Your Vehicle’s Engine?

Most major automotive issues such as engine failures can be avoided by timely service and maintenance.

Reasons to Rebuild the Engine

  1. Engine is overheating quickly. 
  2. Your engine’s oil pump is broken.
  3. Your car starts to consume excessive amount of oil.
  4. Your engine experiences loss of compression and excessive oil clearances.

These are some of the major reasons for a non-functional vehicle, thus bringing about the need for an engine replacement or rebuild.

How to Identify These Issues?

1. Loss of Compression

Loss of compression can be identified by an engine that fails to start, lacks power and misfires. 

However, other symptoms do exist, which can be identified only by having your engine diagnosed.

2. Excess Consumption of Oil

Excess consumption of oil can be identified by first checking to see if there are any leakages through pipes. 

If no leaks, check your engine and see if it’s consuming excess motor oil.

The cause could be worn out valve guides, dried out seals of those valve guides, stuck oil control rings, or excessive cylinder to piston clearance.

There’s also another reason for excessive oil consumption, which is caused by usage of cheap Positive Crankcase Ventilation (PCV) valves.

Thus, getting your vehicle diagnosed, helps determine the cause.

If Positive Crankcase Ventilation (PCV) is the issue, replace this component instead of declaring your engine a lost case.

When your vehicle is experiencing all these issues, it might seem easy to replace your engine, but think about it. 

Your car will give better mileage and emit fewer pollutants if you replace your engine. 

And after all, if you maintain your rebuilt engine well, it has the potential of lasting as long as a new car engine, yet cost you way lesser than that.

What Should an Expert be able to Track While Rebuilding Your Engine?

If you’re having your engine rebuilt by a professional, here are a few issues that the expert should be able to track down, get to the root of it and then fix it.

8 Most Common Causes of Engine Failure

  1. There could be an issue with your heating and cooling systems.
  2. Your engine could overheat. Here are some solutions for your overheated engine.
  3. Your engine could be lacking oil pressure or oil in the first place due to which there is excess friction.
  4. Your car’s water pump could be broken.
  5. Thermostat could be broken.
  6. The engine’s oil pump could be damaged.
  7. Oil levels in the vehicle could be extremely low.
  8. Your engine oil has not been replaced, thus the old oil could get thick and may lose its lubricity.

Determining these issues is the first step you take in deciding whether or not your engine should be rebuilt or replaced.

What to Expect from an Engine Rebuild?

When you opt for engine rebuilding, you should expect that your engine be removed from the vehicle and dismantled. This is commonly called Injector to Pan (pan here refers to oil pan).

After thorough inspection of the engine and its cause of failure, it will be replaced with furnished components such as gaskets, seals, and lubricants.

The most common components that are replaced include O rings, bearings, gaskets, seals, timing belt or chain, valve springs, and the oil pump.

While major components include camshafts, crankshafts, and pistons, which are not changed unless damaged.

4 Benefits of Rebuilding Your Engine

When everything has been furnished as per the inspection in your vehicle, the engine works like it’s new. 

  1. Lifespan of each of the engine parts is extended.
  2. Helps reduce scrap in the environment as it makes use of recycled engine parts.
  3. Connectivity and compatibility with your car’s electrical system is enhanced.
  4. No need to reprogram the engine control unit (ECU) as is needed while replacing your engine.

Thus, rebuilding your engine is any day a more economical, environmentally friendly option over replacement.

So, the next time you’re troubled with your vehicle’s engine, remember to have it diagnosed and then rebuild based on the circumstances.
