General Procedure

NOTE: For specifications refer to the appropriate engine mechanical article. For 2.0L GTDI, refer to the GENERAL SPECIFICATIONS , or for 3.5L Ti-VCT, refer to the GENERAL SPECIFICATIONS tables.

NOTE: Use a straightedge that is calibrated by the manufacturer to be flat within 0.005 mm (0.0002 in) per running foot of length, such as Snap-On® GA438A or equivalent. For example, if the straightedge is 61 cm (24 in) long, the machined edge must be flat within 0.01 mm (0.0004 in) from end-to-end.

Use a straightedge and a Feeler Gauge Set to inspect the cylinder block for flatness.
