Caution: New piston rings may not seat in glazed
cylinder bores.
De-glazing makes the bore "rough" to help seat the
rings. The size of the bore is not changed by proper de-
glazing.
A correctly de-glazed surface will have a crosshatched
appearance with the lines at 15 to 25 degree angles with
the top of the cylinder block.
Use a drill, a medium grit Flexi-Hone and a mixture of
equal parts of diesel fuel and SAE 30W engine oil to de-
glaze the bores.
The crosshatch angle is a function of drill speed and
how fast the hone is moved vertically.
