i started driving my h22 hatch and started to hear a whirring noise on 2nd gear and 3rd gear as i go but when i push the clutch in, it stops. can this be my throw-out bearing or my synchros. i've been busy this whole week with work that i didn't even got a chance to really look at my car, yet. so any info you guys out there might have, pls. feel free to reply. thanks in advance.
