J-Force PRO Parts Engine RE64931
JupiterPro engines are tested to ensure quality. Each component is carefully diagnosed after being cleaned to check for any defects. 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 installers time and money as they come complete with oil pan and/or front cover and in some cases, valve covers already installed.
