Engine Block and Piston Inspection
  1. Measure the wear and taper in direction X and Y at three levels inside each cylinder as shown. If the measurements in any cylinder are beyond the Oversize Bore Service Limit, replace the engine block. If the engine block is being rebored, refer to Step 7 after reboring.
    Cylinder Bore Size
    Standard (New):
    A or I:
    87.010−87.020 mm (3.4256−3.4260 in.)
    B or II:
    87.000−87.010 mm (3.4252−3.4256 in.)
    Service Limit:
    87.070 mm (3.4279 in.)

    Oversize Bore
    0.25:
    87.250−87.260 mm (3.4350−3.4354 in.)

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

    Bore Taper
    Limit (Difference between first and third measurement):
    0.02 mm (0.0008 in.)

  1. Scored or scratched cylinder bores must be honed.
