The lightest contact (-.001") won't even leave witness marks. It may slightly collapse the normal .006" ring to groove vertical clearance and reduce ring seal. If it continues the land will fracture.

There are too many variables to have more than a range.
A 2" long skirt, .001" wall clearance, 2:1 rod ratio, and 3.50" bore with pin offset can run tighter than 1" long skirt, .005" wall clearance, 1.5:1 rod ratio, and 4.60" bore with centered pin.
