Complete Engine Disassembly
Professional Cleaning
Visual Inspection
Dimensional Measurement
Cylinder Bore Inspection
Crankshaft Inspection
Connecting Rod Inspection
Piston Inspection
Main Bearing Inspection
Cylinder Head Inspection
Valve Inspection
Timing System Inspection
Replacement of Worn Components
Precision Machining Where Required
Professional Reassembly
Final Quality Inspection
The exact process and replacement components depend on the condition of the original engine core.
Depending on the specific configuration, the long block may include:
Engine Block
Crankshaft
Pistons
Connecting Rods
Main Bearings
Connecting Rod Bearings
Cylinder Heads
Camshafts
Valves
Valve Springs
Timing Components
Additional components may be included depending on the product configuration.
