Scoring looks like deep scratches in the vertical plane and will absolutely result in loss of compression on these engines. I think jvictormp has good pictures of bore scoring. Or just look up bore scoring on Porsche aluSil engines. They’re subject to the same injector related bore scroring as we are. Also there are a lot of S85 examples if you google it.
