Honing marks are clearly visible all the way to the top on all but the end cylinders. On the two end cylinders, the honing marks are harder to see at the very top of travel. Ring gap at it's worst is 0.64mm (vs. 0.56 in unworn cylinder areas). Inside measurement came out equal as 87.00mm in all positions.
However, the gap between the top ring and the land is 0.254mm. The rings definitely feel loose.
From what you wrote, the lands are worn out and it is time for new pistons, correct?
