No idea how it got scored. 102k miles, all original engine components, never disassembled to my knowledge.
Thanks.

Interesting, thanks for the reply. Was oil changed on a regular basis? Track usage? Does it see VTEC often? I have read a lot of cycl 4 failures with early AP1. Just wondering if it can be prevented as i have a super early AP1 as well.
Thanks.
Thanks.
i think if i had the proper amount of oil or the updated banjo bolts, it would've been fine
now i check my oil every day and have the updated banjo bolts

Status update: I think Bill may be right about that scored wall... Can't really get any clear pictures of it, but it looks like there are streaks on both sides of #4 cylinder each about 2" wide.
Noises can be hard over the internet sometimes, but high compression in #4 was a dead giveaway.
did you do any high spped runs? was the car ever supercharged or turbo?
