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 engine block for excessive wear.

    Piston-to-Cylinder Bore Clearance

    Standard (New):
    0.010−0.035 mm (0.0004−0.0014 in.)
    Service Limit:
    0.05 mm (0.002 in.)
