i just bought a 02 civic coupe and as i was about to leave the parking lot from school i noticed that there was hissing sound when i pressed on the clutch pedal also i feel some vibrations on the pedal when i put my foot on top of it slightly pressing it, then the hissing gets a tad louder when depressed fully. anybody knows what that is?

 

also a bit later when i was on the road home cel turned on help

 

Sounds like your main shaft bearing is going bad. Does it happen in 4th gear?

 

it happens on neutral going to 1st>2nd>3rd, havent noticed it on other gears. i would also like to assume on every other gear *preparing for the worst*

 

i took it on a drive around the block a few minutes ago. it does make a hissing sound everytime i depressed the clutch pedal.

 

I've seen it many times with this model civic at my dealership. The main shaft bearing is going bad. If you could provide a audio or video clip I'll be able to confirm it. Is it almost like a growling type noise?

 

Its not a growing sound. It is most of the time consistent as to what i have observed. I will try and get a clip of it later. It can bately hear it when inget to higher gears though since theres more stress in the engine thus producing more sound. I also try to shift as fast as i can to avoid stressing the clutch too much. Ill get back as soon as i can
