Engine Block and Piston Inspection
  1. Calculate the difference between the cylinder bore diameter and the piston diameter. If the clearance is near or exceeds the service limit, inspect the piston and the cylinder bore for excessive wear.
    Piston-to-Cylinder Bore Clearance
    Standard (New):
    0.020−0.040 mm (0.0008−0.0016 in.)
    Service Limit:
    0.05 mm (0.002 in.)
