Bill....I'm talking about the glazing that can occur from a an engine that was
improperly run-in, and that certaimly does occur. Not a rare "point of contact
glaze" caused by oil break down....
glazing, and it is indeed as skiman762 says, caused by oil breakdown
from excess heat. But this heat can easily be local, confined to the point of
contact between the ring and cylinder wall. The rest of the engine can still
be relatively cold.
The glazing, as I stated earlier is caused by oil getting by the rings (blow-by)
and accumulating on the cylinder wall. Yes, of course the heat of combustion
bakes the oil to the cylinder wall.
How do the guys think it got stuck there ? Bubble gum ? This is the normal
heat of combustion, not an overheated senerio...in fact, we are talking about an
engine that is running sloopy rich...too cool as a mater of fact.
In the case I am refering to, the topic at hand....heat does not "cause" glazing.
The oil that is getting past the rings, due to the improper operation of the engine
and the failure of the rings to seat, getting baked onto the cylinder wall by normal
combustion temperatures....
....results in a glazed cylinder wall, and a poor performing engine. I don't know how
to state it any simpler than that.
Maybe someone can come up with some other type of glaze to throw into the mix.
How about a glazed donut ? Too much oil, or too much heat ?
FBD.
