Cylinder Block - De-Glazing (1-05)
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.
Improper de-glazing will change the size of the bore.
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.
