Whenever the engine of a car is being disassembled, or cleaned, broken parts are replaced and then the entire unit is put back together by professionals, then this process is known as an engine rebuild.

What are the top 3 reasons to rebuild an engine?

The top three reasons behind an engine rebuild are as follows –

Reason# 1

After a detailed car inspection if it is found that its engine is –

• Consuming oil at an alarming rate
• Making unnatural noises
• Leaking fluids
• Overheating frequently even after repairs/parts replacements were made then an engine rebuild is recommended by car experts.

Reason# 2

When the car rating of a vehicle is high but the vehicle is a classic or vintage automobile, its engine is often rebuilt to retain its authenticity or ‘purity’ in a bid to satiate the needs of purists!

Reason# 3

In case a vehicle is being used solely for track days then the chances are high that the vehicle’s engine will be rebuilt after every racing event in a bid to keep costs down.

How much time is needed to rebuild an engine?

Here are the facts – rebuilding an engine is a time-consuming process, period!

You see, if you want to replace an engine, all you have to do is remove the old engine, from the engine bay and put in the new engine, mate it with the transmission, that’s it. Rebuilding an engine on the other hand first demands a thorough inspection of the engine.

In this way, the experts have a clear idea about the parts that need to be replaced within an engine.

Then there is the requirement of the project.

If the rebuild is being done to solely increase the operational life of the vehicle then the rebuilding process will not involve any customization of the OEM engine’s specifications.

On the other hand, if the engine is being rebuilt to increase the overall performance of the car in general so that the owner can have some fun on tracks or when they are on their way to work, then that is going to take additional time.

Why?

Well, after rebuilding the engine, the car has to be tested and the ECU of the vehicle has to be remapped as well in a bid to ensure the modified engine is neither running rich nor lean.

In a nutshell, rebuilding an engine will take a lot of time but the results will be satisfactory!

Rebuilding an engine is pretty costly!

Rebuilding an engine is labor-intensive when compared to engine replacement. Additionally, rebuilding an engine is pretty costly as well but the expenses don’t even come close to replacing an engine. This is why, car owners often choose to rebuild their car’s engine instead of replacing it.
