Here's the video:
1998 Integra GS-R with 220,000 miles (all mine) on original engine. Owned her since new (I'm pretty attached and a bit emotional right now!) I was racing along the other night on an empty road with another GS-R, and right around 8000 RPM lost a lot of power, cylinder misfire codes came on (for 2,3,4, multiple, and p1399), and I had to limp home two miles in panic and shame.
I checked the timing and it was fine. I replaced the rotor, cap, and plugs because they looked really bad, and I checked/adjusted the valve clearance while I had the cover off. This video is from after that work, but it was making the same noise before. Something is obviously striking/colliding, and it sounds like the top end. You can also hear its frequency is about 8-9 times a second, half the rpm of 1,100 or 18 rotations a second, so it's probably cam/valve related.
Can you guys tell me what's up? I'm guessing I fried a valve.
