Product Upgrades
Your remanufactured engine is tested in several specific ways after being assembled; Multiple Pressure tests. Each component is carefully checked after being cleaned to see if cracks or other defects exist in the casting. After being assembled, we pressurize the water jacket with 30lbs. of air pressure. As a result of these tests, you can be sure your unit will not have coolant leaks. SIM test, After pressure testing, our final check of engine performance is a spin test. We turn the engine at 400 RPM with oil pressure lines attached. The test measures compression on each cylinder, oil pressure, oil flow and allows an easy visual check that oil is reaching all critical areas. This test also allows the rear main seal to be checked for leaks. We produce most engines as long block assemblies that ship with a finishing gasket set and a new oil pump. We also produce many of the most popular engines as dressed alternatives. These engines save installer’s time and money as they come complete with oil pan and/or front cover and in some cases valve covers already installed.
