Can carbon score a cylinder and put fine scratches in bearing? I'm watching a guy rebuild an Alpina B7.

20.40 mark. He goes through a couple of cylinders and shows the scoring. He's German (Frankfurt) but his english is exceptional.Is there a point in the video where damage (or lack thereof) is shown?

Ultimately he was concerned that the engine would start burning oil after he'd sorted out everything (ex timing chain service). This is an Aluminum-Silicon block without iron sleeves. The walls are acid-etched to expose the hard silicon which gives the walls a dull color. There are only a couple of shops in Europe which have experience with this type of block and we'll know the results in his next episode.Thanks. And 22:16 showed the other bank.
Question: When describing the second bank & when tallying the overall damage, he used the word "destroyed" three times. What was the negative result of all that scoring? Unacceptable oil consumption? Or lead the engine to seize up? or....
