Hello, everyone.
I'm almost embarrassed to ask this stupid question. All this talk about
compression testing on a wet or dry ring surface dredged up an old curiosity
I've had.
I swear, it seems to me sometimes that oil actually soaks into metal. Or
maybe it's just that there is a thin film of oil on cylinder walls that never
seems to go away. Every head I've pulled, if I run my finger on the cylinder
wall, it "feels" lightly oiled.
Are oil molecules too big to squeeze into metal pores? Isn't this how cast
iron frying pans are "seasoned" with oil?
Thank you, everyone.
Terry (hiding his head and not saying which Terry)
