Can you micropolish too finely?
When Porsche built these cars in the 1980's, cranks weren't micropolished...
Now, its common place...
I am sure that engine builders can polish journals to an absolute mirror finish, but, they don't.
Is that due to a cost or technique issue? Or, is it simply that a less than perfectly polished journal holds oil better?
There are high end engine builders on youtube that polish the journals to a mirror finish with buffing compounds.
Yet, most don't...
Why?
No benefit to doing it? Harm to doing it?
