Cylinder Block Distortion

CYLINDER BLOCK DISTORTION
^ Using a scraper, remove gasket on the cylinder block surface, and also remove engine oil, scale, carbon, or other contamination.

CAUTION: Be careful not to allow gasket flakes to enter engine oil or engine coolant passages.





^ Measure the distortion on the cylinder block upper face at some different points in six directions with a straightedge and a feeler gauge.
Limit : 0.1 mm (0.004 inch)
^ If it exceeds the limit, replace cylinder block.
