Following is a quick summary of the process; once motor arrives at DR facility it is transferred to the engine department, one logged in and paper work filled out the engine goes through a thorough examination. All components are checked, bearings, gears, crankshaft, rod, piston, valves etc. DR keeps extensive notes on disassembly process. Once disassembled certain components will undergo a preliminary wash for further examination. Once the dissemble process is complete, DR will compile a build estimate. Once DR is equipped with teardown notes and preliminary notes, DR will contact client and schedule a time to discuss their engine either in person or by phone. For clients unable to communicate in person or via telephone. DR will compile a comprehensive email outlining the issues with the engine and estimating the build costs. During the estimate phase DR will answer all questions and cover all options. The goal here is to educate our clients so they can make the best decisions for their situation. Once DR and Client have agreed on a course of action. DR will begin the build process. Performing necessary machine work, cleaning and prepping for reassembly.
