Connecting Rod Bend And Torsion
Bend:
Limit: 0.15 mm (0.0059 inch) per 100 mm (3.94 inch) length
Torsion:
Limit: 0.30 mm (0.0118 inch) per 100 mm (3.94 inch) length

Cylinder Block Distortion
1. Clean upper surface of cylinder block.
Use a reliable straightedge and feeler gauge to check the flatness of cylinder block surface.
Check along six positions shown in figure.
Block surface flatness:
Standard: Less than 0.03 mm (0.0012 inch)
Limit: 0.10 mm (0.0039 inch)
2. If out of specification, resurface it.
Resurfacing limit:
The limit for cylinder block resurfacing is determined by the cylinder head resurfacing.
Amount of cylinder head resurfacing is "A".
Amount of cylinder block resurfacing is "B".
The maximum limit is as follows: A + B = 0.2 mm (0.008 inch)
Nominal cylinder block height from crankshaft center: 246.95 - 247.05 mm (9.7224 - 9.7264 inch)
