100% visual inspection, sorting and grading of core during tear down.
100% magnaflux inspection of all blocks for cracks.
100% air gauging of all cylinder bores for diameter and roundness after final honing operation.
All crank main bearing bores and all cylinder bores measured for diameter and distortion.
Coolant passageways – All engine assemblies quantified for water jacket, head gasket, and casting leakage using pressure decay testing.
Oil passageways – All engine assemblies quantified for oil gallery, gasket, and casting leakage using pressure decay testing.
Sims Testing – All engines are cold motored and checked and measured for proper torque to turn, cylinder compression, oil flow, oil pressure as well as audibly monitored for any unusual noises. All sealed units are tested for oil and coolant leaks.
One block per engine family is laid out daily and checked for all critical and high impact characteristics as defined in our control plans. These measurements include surface finishes, surface flatness and cylindricity.
