Buying A Used Engine VS Buying A Remanufactured Engine
When considering a remanufactured engine vs a used engine, make sure you can answer the following situations to determine the quality of the engine you are getting.
- Is there hidden damage to the used engine, like microscopic cracks that may show up after the used engine warranty has expired? If the used engine was in a wrecked car, this is a big possibility. However, with our remanufactured block and new components, you can rest assured that the engine you order from us has been tested and is in great condition.
- Can you be 100% sure of the mileage on the used engine? On a remanufactured engine from Roadmaster, you can be assured that our engines have no in-vehicle miles put on them.
- Do you know how the used engine has been treated and in what condition it is in? With a remanufactured engine from Roadmaster, you know the utmost care has been given to build each engine to new engine specifications. All the internal parts are new, and the remanufactured engine you buy can be trusted to last you a long time.
Roadmaster’s remanufactured engines are built using the finest new or core blocks and are built with brand new components.
Remanufacturing and Testing
Remanufacturing is the process of reconditioning a “core” or worn out used engine to meet industry standard specifications.
Engines suffer from countless sources of wear and tear that can eventually destroy them. While a properly maintained engine might last hundreds of thousands of miles, a poorly maintained one can and will fail. When engine failure occurs, there are several choices, the most cost-effective solution is to choose a remanufactured long block engine.
Building a remanufactured, rebuilt replacement engine that meets original requirements is no small feat, but it’s the only way to provide the most reliable and respected remanufactured engines in the industry. Roadmaster Engine World does this by using quality parts with proven and constantly improving processes. These fully reconditioned engines are assembled with precision and impeccable quality control.
A rebuilt engine is one that has been remanufactured to prescribed standards and specifications by highly skilled machinists using state-of-the-art equipment and components. During this process many new components are installed that meet or exceed original equipment performance standards. Remanufacturing is done with precision and involves fully disassembling the entire engine, cleaning all the components and resurfacing or replacing parts that are not in good condition.
Frequently, rebuilt engines are better than the engines originally installed at the factory. They are dependable, reliable and backed by excellent warranty programs.
Engine Blocks, Rods, Crankshafts and Cams are thoroughly cleaned, tested for wear, straightness and cracks.
What is Sim Testing and How Does it Differ from Dyno Testing?
Dyno testing – is a test to an engine with it operating out of the vehicle under its own power. This means running and firing under fuel and with a load applied.
Sim tested (or simulation testing) – Is a test performed by all manufacturers of rebuilt engines but is often referred to incorrectly as Dyno testing. Sim testing is the process of using a machine to spin the engine at roughly 750 RPMs. This allows us to test for compression, proper oil pressure and any noises. It also allows the engine lifters to be pumped up thus aiding in eliminating any start up tapping. The engine is not under its own fire or running on fuel at this point.
The reasons it is done in this manner, as opposed to a true Dyno test, are as follows:
- The cost (it would increase the cost of each engine by $1000.00-$2000.00)
- The man hours involved (it would increase the end time for rebuilding by another 8 hours, due to having to dress, run, and undress each engine)
- Equipment (we would have to have in house every computer, harness, fuel management system etc for every engine we rebuild, which is roughly 3500)
So overall – it is not feasible to Dyno test because it would end up costing you twice as much for each engine. The Sim test provides an excellent baseline, and allows us to weed out any mistakes made in the re-manufacturing process.
