Roadmaster’s remanufactured engines are built using the finest new or core blocks and are built with brand new components.
Remanufacturing Engines 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.
Frequently, remanufactured engines are better than the engines originally installed at the factory. They are dependable, reliable and backed by excellent warranty programs.
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. Engine Blocks, Rods, Crankshafts and Cams are thoroughly cleaned, tested for wear, straightness and cracks.
Here at Roadmaster we have ASE builders who build our diesel engines and only diesel engines. For our gas engines we have the highest-technology equipment, the most intelligent engineering and the best practices in engine remanufacturing today. This commitment to manufacturing technology allows us to build the best remanufactured engines.

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 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. The SimTest machine flows preheated oil through the engine while spinning the rotating assembly. 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 SIMTEST is a simple engine test that standardizes quality and reduces any possible comebacks. The relative success or failure of a remanufactured engine is a matter of physics, plain and simple. This machine checks it all: compression, pressure maintenance, oiling, valve adjustment, turning torques and a host of other functions.
These are checked against rigid industry standards. With the SIMTEST machine, we systematically test all mechanical functions and procedures involved in engine remanufacturing. It’s accurate and dependable and helps assure our guarantee to you for the highest quality remanufactured engine possible. So, the next time you order a remanufactured engine from us, rest assured that it is the highest quality engine
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.
Short blocks are falling into disfavor because by the time you buy the short block and the mandatory lifters, gaskets, oil pump and such you end up spending more money than you would have spent buying a long block in the first place. Also if you buy the short block you may have to pay your mechanic more money to install it because it takes more time and then when it’s all finished the engine warranty only covers the bottom (short) half of the engine. See, you’ve got to buy gaskets just to put it together. It would be nuts to put an engine in without a new oil pump. The camshaft warranty is no good without new lifters and besides it’s just good policy, etc. You get the idea.
There’s only one way to achieve proper surface finishes and geometry on crankshafts: QPAC Micropolishing Equipment. Roadmaster Engine World is one of the only remanufactured engine companies in this area that has the QPAC micropolishing machine. This micropolishing procedure is done on every crankshaft we supply to our customers whether it’s in a crank kit, a long block or short block application. Roadmaster Engine World crankshafts are profilometer tested for finish quality and integrity. Strict quality control standards and the latest technological advances are combined to ensure and secure that all production expectations are met. In taking this extra step on each of our crankshafts, this improves the RPM and fuel efficiency in each of our remanufactured, rebuilt engine applications.
The Roadmaster Engine World remanufactured long block engine meets the high standards of Roadmaster’s remanufacturing process at an affordable price! Every engine is tested to eliminate problems prior to actual engine installation. The Roadmaster Engine World remanufactured long block engine offers a competitive warranty at a fair market price!
