When your engine arrives at our facility, we perform a comprehensive inspection to assess the condition and identify hidden damage as outlined by the OEM documentation. Depending on condition, your engine then follows a rigorous process which entails, but is not limited to, disassembly, cleaning, module assembly, testing, and final inspection.
