Look here www.volny.cz/veitel/prelude/vtec.mp3 at the noise my engine is making. It is Prelude 1995 VTEC with H22 engine with 80000km (60000miles).

The strange sound is going somewhere from the timing belt location, looks that it is not from any power steering, alternator etc. It makes the sound only at 1000rpm, I can go there from idle or droping from higher RPMs, it doesn't matter. It does not make it anywhere else in the RPM band. Basically when the engine stays idle, the sound is normal (listen beginning of the MP3). When I just touch the gas pedal, so the RPMs goes to cca 1000, the strange sound starts. When I go higher (1100rpm or so), the sound disappears. What can it be??

The sound is since I have my engine rebuild, autotensioner removed, checked and installed back. It was fully functional so I think it is not because of it. The exact same sound (at 1000rpm and also at 1800-2000rpm) made my previous F22 Prelude (year 1994), but there is no autotensioner, there is a manual one. The sound was really the same, I remember it. On the F22, the sound stoped after I rebuilt the engine. Here with the H22 I rebuilt the engine and the strange sound starts!!!

Someone please help me.

 

hmm, odd. My f22 sounds the same way on colder days....

sounds like someone going PPBPBFPBTPBPBFPBPFPBTPFBTPBFPBTBPTFPBTBBTPFT with their lips

I just had my timing/a/c/power steering/water pump/seals all done, and it's less than it was... but sounds similar. I thought it was normal.



How about a nice mp3 of a slow rev to redline and back down? :thumbup:

 

It's definetly not the powersteering, alternator and A/C compressor. I disconnected them and nopthing changed. So its somewhere near the T-belt.

 

does yours have a counterbalance belt? cause i did the tbelt on mine (99' h22a4) and it had a counter belt and the tension was a little too tight and it made that noise.....

 

yea i just listened to it again with someone else here, it is definitely one of the two belts that is too tight, if yours has a counterbalance belt.... if not, even though it uses an auto tensioner it is still possible it is too tight, because when ytou re-use your auto-tensioner instead of replacing it you have to do a couple things (which I forgot since I replaced mine) otherwise that could cause the tension to be too much, definitely is a belt that is too tight though.....

 

Yes the engine is H22A2 and it has a balancer belt. And yes I reused the autotensioner - should I do something to loose it?

 

Problem solved. It was really T-belt that was too tight. The autotensioner was fully functional, but installed wrong way.

 

So the noise came back after 2 miles driving . But when i was idling with the timing belt not so tensioned, the sound was not there. Maybe when I started to drive, the big tension came back. Anyway, I'm going to make the auto to manual tensioner conversion. Today I bought an aftermarket pulley for about $11, which is a good price I think :thumbup: . It has "KOYO JAPAN" stamped on itself and I think the same is on the original one.

 

OMG, I have made auto to manual tensioner conversion on my H22, but the sound is still there. When I tight the belt according to the Helms, the belt doesn't vibrate while running, but my engine makes that strange noise. When I make the tension little loose, the noise dissapears, but the timing belt vibrates on its "longest way" - between exhaust camshaft and crankshaft. The vibrations are about +-0.5cm (+-0.2inch) and the belt doesn't jump over a teeth. Is this OK? What sound is that?
