2.5k+ RPM KNOCK UPPER END

[Kev1990]

F22A1 engine ever since I've owned this car it's had this upper end knock when going in higher rpms for years it's been this way and hasn't seem to gotten worse but I'm not sure if it's normal or not a valve adjustment has already been done and it still sounds like this I have a video down below you can watch and try to listen tell me if my engine sounds healthy I was holding it right at the valve cover when recording BTW halfway through the video a motorcycle was flying by so ignore that. I also have pictures that I'm posting below of my spark plugs they look a little bit white like it's running lean or something anyone who can help me thank you in advanced. BTW that's the same spark plug pictures but just of different angles and it's cylinder 2 spark plug

Does anyone think this is a normal sounding high milage engine or can you hear the knocking in the video?

It's the knocking that you can hear while the rpms are going up can't hear it much at steady rpms

dude, I'm having the same exact issue. Still can't diagnose the problem. I've been a little hard on my car to see if I would cause any damage. I haven't seen any metal shavings and the knock hasn't gotten worst. I have no clue what it is. Here's my thread if you would like to read through, maybe it could help?

did you ever figure the problem out?

Nope it's not worrying me to much as it is not getting worse.
