Apples and Oranges
This is a good question and here at remanns.com we get asked this a lot. When you are faced with having to make a decision between getting your engine rebuilt or buying a remanufactured engine from remanns.com, you need to know the difference in order to make the right choice for you.
The Remanufacturing of Engine Components
First let’s look at the definition of remanufacturing as it relates to engine components.
A Remanufactured engine means – to recondition a component to as close to the original state or better in some cases when a component from the original manufacturer has been identified as having a defect. If a part that is going through the remanufacturing has wearable components, these components will be replaced.
The core or engine block, cylinder walls are checked to make sure they have the correct tolerances and restored to OEM specs.
During the remanufacturing process the pistons, connecting rods, rings, bearings, camshafts, lifters, and oil pump are installed. All bearing surfaces are also restored.
Part on a rebuilt engine are inspected and cleaned, the parts that are replaced are only the ones that show visible wear. Most serviceable parts are reused as long as they fit within the OEM tolerance limits. Unlike a remanufactured engine, rebuilt engines may only come with a very limited warranty instead of a full 5 year no fault warranty like remanns.com.
A concern to you is that with a rebuild, there could be damage to the used engine that is not visible to the human eye, like cracks or heat stress.
In conclusion the safest and certainly the most reliable way to go is to purchase a remanufactured engine.
