I have a 95 civic cx with 173,XXX miles. I got it about a month ago. It would once and a while make a slight squealing noise when turning or accelerating, but I didn't think much of it. Today it started getting louder and more frequent, and it squeals also when I rev match downshifts, specifically when the motor is revving up freely with the clutch in. It seems to occur at more random times now so I'm not sure where to start. Also just for reference the car is bone stock. Any ideas?

Thanks Guys.

 

If it's doing it w/o load (clutch in) just have a buddy listen under the hood and try getting it to do it again. It's probably just a belt and does it around a certain rpm range.

 

It seems to occur at inconsistant rpm ranges. It does not occur when the car is stationary in neutral, even when you rev it. Could this be a clutch related problem?

 

Squealing noises are usually belts. Are you sure it's squealing and not a high pitched grinding noise?

 

Sounded more like a squealing noise, but I'll listen closer next time I'm in the car. If it were a high pitched grinding noice, what would your suggestion be?

Thanks

 

Tensioner pulley. But even then it should be constant and not intermittent.

 

If you hear the noise only when the clutch pedal is depressed, the clutch throw out/release bearing may be bad.

 

^^ This is what I wasthinking, but it also makes the noise when it is not depressed. It is louder and more frequent when it is depresseed though.

 

any more ideas guys? it is now squealing even after i let off the clutch when the cars in neutral, untill i rev it again. im starting to think its a belt now.

 

How old are the belts?

 

older that sh*t for all i know. they were on the car when i got it.

 

If it were the belts, it wouldn't be "at random rpm". It would be when it was cold, or once it warmed up. Either, or, rarely both. As for it being the throwout bearing, how is the pressure plate feeling. Does the engagement start at different depression levels ever? That is also indicative of a bad bearing.

 

well its usually at lower rpms. and it occurs more when its cold, but occasionally when its warm also. its weird. and no, it always engages at the same spot.
