Range Rover (LH) V8-3.5L (1987)
Measuring Cylinder Bore
3. Check the cylinder bore dimension at right angles to the piston pin 40-50 mm (1.5-2 inches) from top.
Measuring Piston Dimension
4. Check the piston dimension at right angles to the piston pin, at the bottom of the skirt.
5. The piston dimension must be 0.018-0.033 mm (0.0007-0.0013 in) smaller than the cylinder.
6. If new piston rings are to be fitted without reboring, deglaze the cylinder walls with a hone, without increasing the bore diameter, to provide a
cross-hatch finish. After honing, thoroughly clean the piston bores to remove all traces of foreign matter.
