Each block is magnafluxed for cracks and checked for any visible damage to the block or threaded holes before being repainted. Five CNC machining centers are programmed to precise specifications that meet or exceed those established by the OEM for each engine block. After the engine block is bored, decked, and chamfered, each cylinder is honed with the specified OEM cross-hatch pattern. All gauging of all cylinder bores for diameter and roundness after final honing operation. Quality audits are performed to ensure that the cylinder meets specifications. All new pistons, rings and bearings are installed in every engine. One block per engine family is laid out and checked for all critical and high impact characteristics as defined in our control plans. These measurements include surface finishes, surface flatness and cylindricity in the cylinder bores. Every head is resurfaced and completely inspected for any visible damage or cracks to the casting or threaded holes. Valve seats are machined, inspected and replaced if necessary. The cam bore is air gauge checked on overhead cam engines and machined if required. All new valves, seals and lifters are used in every head. All plugs and fittings are replaced with new. All head and valve assemblies are quantified for leakage. Each connecting rod is measured against OEM specifications. The piston pin bore and bearing bore are measured with air gauges for proper dimensions. New torque to yield rod bolts and nuts are installed. Crankshafts are machined on a fully automated Ju crank CNC crank grinder. All oil galley holes are chamfered and brushed after machining. Each crank is inspected for cracks, bow and all applicable run-out specs for rod and main journals. Sims Testing – All engines are cold motored and checked and measured for proper torque to turn, cylinder compression, oil flow, oil pressure and any unusual noises. All engine assemblies quantified for oil gallery, gasket, and casting leakage in the oil passageways
