Rep Power: 0

Howdy,

Well, that's how I'm reading the table. Perhaps I mis-interpret it. But the manual for my 2000 Civic DX appears to indicate that valves need to
be inspected (perhaps adjusted too) ONLY at 30,000 miles. Otherwise, if they were to be inspected EVERY 30,000 miles, then the table would
indicate the "bullet point" appear at the same interval as the spark plug intervals just below it. Interesting. Thoughts?

if you start hearing the tic-tic-tic too loud when cold, it's time for sure

I would interpret it the same as you are.

No need to adjust until they make noise but maybe that 30k mile check is a wayo to make sure nothing slipped though when being made? A sort of quality check, idk.
