Engine and Cooling Systems Cylinder Honing
The cylinder bore must be de-glazed whenever new piston rings are installedA light honing with fine stones removes only very small amount of materialA proper crosshatch pattern is important to provide surface that will hold oil, and allow the rings to seat properlyIf the crosshatch is too steep, oil retention will be reducedA crosshatch angle which is too shallow will cause ring vibration, poor sealing, and overheating of the rings due to blow-by and reduced contact with the cylinder wallService life of the pistons and rings will be greatly reducedNOTE: Nicasil cylinder can be lightly honed with 320 grit stone hone but can not be oversized
