During each power stroke, the cylinder walls are subjected to very high temperatures, often 4000
degrees F or higher. This period is very brief but nevertheless, long enough to cause oxidation of
minute quantities of some of the lubricating oil on the cylinder walls. Some of this oxidation will
settle into the "valleys" of the honed cylinder wall "scratches." Eventually this situation will fill
the "valleys" of the cylinder walls creating a smooth, flat surface. This is also a normal situation;
however the ring break-in process practically ceases when these valleys become filled or "glazed"
If this "glazed over process occurs before break-in is complete, in modern day language, "you
have had it." Excessive oil consumption resulting from incomplete ring seating will present itself
and the only certain remedy is rehoning the cylinder walls.
