Engine Block and Piston Inspection
  1. Measure the wear and taper in direction X and Y at three levels in each cylinder as shown. If the measurements in any cylinder are beyond the Oversize Bore Service Limit, replace the block. If the block is being rebored, refer to Step 7 after reboring.
    Cylinder Bore Size
    Standard (New):
    A or I:
    86.010−86.020 mm (3.3862−3.3866 in.)
    B or II:
    86.000−86.010 mm (3.3858−3.3862 in.)
    Service Limit:
    86.070 mm (3.3886 in.)

    Oversize
    0.25:
    86.250−86.260 mm (3.3957−3.3961 in.)

    Reboring Limit:
    0.25 mm (0.01 in.) max.

    Bore Taper
    Limit:
    (Difference between first and third measurement) 0.05 mm (0.002 in.)

  1. Scored or scratched cylinder bores must be honed.
