About PROFessional Powertrain DO15 Oldsmobile 307

This engine is remanufactured using the most technically advanced methods - incorporating both CNC machining and DC torque equipment. All components are inspected to assure viability and then verified by Quality Control Personnel. All sub-assemblies and components are both pressure and vacuum tested prior to being installed. Once assembled, state of the art computer controlled pressure testing is performed as a final verification of casting integrity. Final testing is done with our proprietary “ProTester Max” at 600 RPM. If applicable both VVT (Variable Valve Timing) and DOD (Displacement on Demand) units are physically operated and 100% confirmed. Compression, oil pressure, oil flow and four, ninety degree stop and match readings are verified to assure your engine will meet or exceed your expectations. Fluorescent dye within the testing oil is used as a countermeasure to find any possible oil leaks, including the crankshaft rear seal. This state of the art testing far surpasses a “hot fire” engine. Engines come as long block assemblies that ship with a finishing gasket set and a new oil pump. We consider it a privilege to provide you with engine assemblies that we remanufacture with PRIDE!
