ok...i have a 2k1 ex coupe, automatic.....i drive it lightly, usually shifts itself at 3,000 or 3200. here and there i push it to 4500 when merging in the dallas highways or passing a semi who won't let me in.... so what i've heard is that high rpm can make the valves click after awhile. Is this true? does hitting high rpm do damage to my engine? I wanna keep everything in good shape, and im wondering if i'm hurting it. I never change oil later than 3000 miles, either.

well i prolly take mine to redline daily. i did that on my old s10 for 2.5 years and never had any ENGINE or TRANNY problems, not to say i didn't have other problems though but they weren't related to me taking it to high revs.
It doesn't matter anyway, fuel cutoff is 7200rpm so it would be hard to hurt ur engine anyway. Unless of course you miss 4th and put it in 2nd like i did once on the highway, my tach needle went all the way to like 8500 or 9k i can't remember, that WILL hurt ur engine but only after long periods of time.
Ur fine, specially in 4500 range, man thats when vtec engages!!!!
complacated answer is sort of, and the short answer is no. higher RPMs will always cause more wear on the engines internals, however unless were talking about running the car near redline for an extended ammount of time (and i mean a while) its not going to have any signifagant effect on engine life, given otherwise normal driving conditions and proper matainace.
I don't know about the new civics, but the Si's valves will click after 30,000 some miles and need a valve adjustment. However, I don't think that will happen with the new ones.
Joe - If you were talking to me, you should check your clearences. It's not me who decides when to do the valves, Honda does. Anyways if you were to do the 30,000 mile service it should have been done. I've got 60,000 on mine and it's going strong too, however the valves are still beyond factory spec and could mean an extra couple Hp when put in spec.
Seriously though, If you have 45K on you B16 and you haven't done a valve adjustment, please do!! You will thank me later, it does make a difference.
Honda's make their power at higher RPM's.....they were engineered to have a 7200 redline.....use it up....[IMG]i/expressions/face-icon-small-smile.gif[/IMG]
....but not while daily driving....
True, our engines are engineered for high rpm's. But the thing is, all engines have a life-span that fluctuates depending on how it's treated throughout its life.
In general terms:
If you have a guy who drives hard and redlines once a day, VS. a more relaxed driver who never redlines, chances are good that the more relaxed driver will get a longer than average life-span out of his engine in the long run, not to mention that he will also likely have lower maintenance costs....... Whereas the hard driver will get maybe average to below average engine life-span, and probably higher maintenance costs. Again, this is in general terms, and you will always get exceptions to this.
So the answer to your question is yes and no... depending on what you're expecting to get out of your engine in the long run.
every time i drive my 2k1 EX coupe i hit the 5000 rpm range, i usually shift around 5500 or so and i redline it every once and a while. honda made these engines to make their power at high rpms. thats why they are called "high-rev" engines. (at least the VTEC engines are) so dont worry, especially with your automatic....that will take care of your engine. but if youre still worried synthetic oil always helps
