I'm about to pay honda £100 to redo the valves because i can't find an answer anywhere on the interweb if my car sounds normal or not after me having a go at DIY valves, shes an 02 ap1 all 16 valves where very tight beforehand she sounded a bit like a diesel before but now more pronounced, maybe paranoid ears or i fecked it up. please chime in. https://youtu.be/gUvBK05f4v0

Sounds like timing chain. You replace the tensioner?

i haven't touched the timing chain tentioner yet, i only did the valves because i had idle shake which seems to be improved 75%

when you rev it it sounds like tct needs to be replaced. but at idle it does sound a little noisy.

Noisy valves arent tight. Tight valves burn, loose valves tick. If it sounds like a diesel, the valves are LOOSE. Check that you used the right size feeler gauge, and adjusted them to the right "feel." Its something that you will never know how to feel on your first few attempts. Just make sure the smallest feeler gauge ALWAYS fits in. Loose valves are only noisy, over tight ones can kill an engine. If you arent confident, let Honda do it. $100 is super cheap. The dealer I work at still wants to charge me $200, so I did it myself. Took me 4 tries to do it right, dont feel bad.

And after watching that video, you definately need to tighten those up a bit. Sound pretty loose but at least you adjusted them the safer way!

Thanks this gives some reassurance, I think ill go with the Honda redo and see how out i was

You work at a dealer and they want to charge you 200? That sucks. Don't you have a colleague who wants to do it for you after hours?

so i also asked a bunch of people on youtube (s2000 owners lol) what they thought and one guy was kind enough to make a short vid to compare to https://youtu.be/0swcKqloAlA he has upgraded intake but the "tappery" sound i have been stressing about seems to be the same i think, bearing in mind i used my iphone n stuck it really close, starting to wonder if mines ok (save the £100) ???

To me the second video has a healthier, more normal sounding F20C. There's so many factors that can cause noise, but timing chain could indeed be one of them, new spark plugs, valve adjustment can affect noise for better or worse, but what's important with that is that they are in a safe range within spec. Though the quality of the noise feed from the cell phone is also better on the second video. How many miles are on your car vs. your friend's?
