I and some other people have this noise coming from the timing belt area (H22, 800-1000rpm): http://www.volny.cz/veitel/prelude/noise/noise.mp3

The noise started immediately after the timing belt change (plus water pump, auto to manual tensioner conversion).

I tried everything, the result is: when I loose the timing belt a bit (I can, I have the manual tensioner), the noise is gone. When I tighten it to spec (according to the Helms), the noise is there.

Can the timing belt itself be greased/oiled so it makes this noise itself? Can I try to degrease it with some alcohol? The degrease looks pretty easy, so I will try it if it is safe - just to remove the valve cover and rotate/degrease the belt + cam gears by some towel.

 

i wouldnt spray anything on that belt , im sure its hte pully or the tensioner squeeking...... timing belt shouldnt squeek....

 

Don't touch the belt with oil! I did a HG swap and the belt got saturated with oil.... and snapped a month later!

I wanted to remove the oil (that could be on the belt), not get the oil there.

 

mine did the same noise, belt could be too tight

 

I would say the noise is probably a bearing from the belt being too tight. If you think there is oil on the belt you need to find the oil leak. Try spraying brake cleaner on the blet while its moving after the leak is fixed.

 

brake cleaner will eat away at the rubber wont it...i dont think spraying brake cleaner on the belt is a good idea...

 

It is too much tension on the tensioner! Adjust it to where it just doesn't make that noise, and then check the deflection of the belt? I think it should still be it the limits! If you have it all torn apart, check the tensioner to see if it is still in okay condition! I had one go bad in 2 mos because of a t-belt too tight! The belt didn't break, But the bearings in the tensioner took a beating and didn't last very long? Is the tensioner a oem honda one?

Yes, the manual tensioner is from h23. But when I put ther the h22 autotensioner, the noise is also there (the autotensioner is ok). The tension seems to be the same as the right tension of the manual one (according to the helms).

If I loose the belt that the noise is gone, the belt seems to be too loosen. At some engine speed, the timing belt "vibrates" on it's longest way - between exhaust camshaft and the crank. Is this ok?

you have to find the optimal point in wich the timing belt long side dont vibrate as much(and make noise) and it dont make the noise that you posted.
It might take a couple of tries, but you'll get it.

I probably will, but I dunno what the right tension should be and how much vibrations is safe...
