If out of specification, replace piston ring. If gap exceeds maximum I When replacing the piston, check the cylinder block surface for CONNECTING ROD BEND AND TORSION NCEM0026S04 Bend: Limit 0.15 mm (0.0059 in) Torsion: Limit 0.3 mm (0.012 in) If it exceeds the limit, replace connecting rod assembly. CYLINDER BLOCK DISTORTION AND WEAR NCEM0026S05 Clean upper surface of cylinder block. Block surface flatness: Standard Less than 0.03 mm (0.0012 in) If out of specification, resurface it. Amount of cylinder head resurfacing is “A”. The maximum limit is as follows: A + B = 0.2 mm (0.008 in) Nominal cylinder block height 213.95 - 214.05 mm (8.4232 - 8.4271 in) If necessary, replace cylinder block.
