Cylinder Bore Inner Diameter

WARNING: This page is about a different car, the 2007 Nissan Pathfinder. However, it is still accessible from the selected car via links, so may be relevant.

Using bore gauge, measure cylinder bore for wear, out-of-round and taper at six different points on each cylinder. ("X" and "Y" directions at "A", "B" and "C") ("X" is in longitudinal direction of engine)
Standard inner diameter:

95.500 - 95.530 mm (3.7598 - 3.7610 in)

Out-of-round (Difference between "X" and "Y"):

0.015 mm (0.0006 in)

Taper limit (Difference between "A" and "C"):

0.01 mm (0.0004 in)

If the measured value exceeds the limit, or if there are scratches and/or seizure on the cylinder inner wall, hone or re-bore the inner wall.
Oversize piston is provided. When using oversize piston, rebore cylinder so that the clearance of the piston-to-cylinder bore satisfies the standard.
CAUTION: When using oversize piston, use oversize pistons for all cylinders with oversize piston rings.

Oversize (OS) : 0.2 mm (0.008 in)
