clutch
 

whenever I start up my civic the car is so loud and the noise doesnt go away until i push the clutch in, a friend of mine said its probably the throw-out bearing or something like that. does this mean my clutch is on its way out?? Any input is appreciated

what is loud? Like loud exhaust? A rattling? Metal on metal? Grinding? Squeaking? Details are crucial

the noise is hard to describe, it sounds like a loud idle id have to say.

its definetely not the throwout bearing if it goes away when u push the clutch in the only time u hear the throwout bearing is while u are depressing the clutch

"4. Common Problems

Almost always I read this issue and it is true for just about ANY manual vehicle you will ever own. If you are hearing a dull grinding/sliding sound while in gear your mainshaft bearing is going (aka the ISB or Input Shaft Bearing). This bearing is located on the opposite end of the mainshaft and gets worn quickly because of the clutch pushing it in and out. This bearing also takes the brunt of the torque from your engine. When you replace this bearing it's best to just replace all of the bearings at once, and always use OEM Honda bearings. The install itself is not bad but if you've never pulled apart a transmission I'd suggest against doing it yourself unless you have someone who knows what they're doing to help."
