Use a straight edge and a feeler gauge to check the six positions for flatness. Refer to Illustration 2.

Inspect the top of the cylinder block for cracks, damage, and warpage.

Inspect each cylinder bore. There should be no scoring, rust or corrosion. Use a 1P-3537 Dial Bore Gauge Group in order to measure each cylinder bore. Each cylinder bore should be measured at the top, middle and bottom.

If the cylinder bores exceed the service limit, the cylinder block must be renewed. Refer to Specifications, "Cylinder Block" for the bore diameters and tolerances.

Note: The flex-hone process must not be used on these engines.
