    Unhappy EP3 engine whining noise! please HELP

    Hi everyone,
    Im new to this forum.
    My EP3 makes this whining noise when accelerating, very obvious from 2k rpm up til VTEC noise takes over.
    it is very annoying when cruising on highway.

    The drive belt seems old but spray belt dressing does not make ANY difference to the noise. The tranny fluid has also just been changed with honda MTF06, which made no difference either.

    what could be the cause?

    Heres youtube video.

    Thanks a lot!

    I think your car has this very uncommon problem that occurs in almost all cars, you know the previous owner must have installed a super charger. Not many people are that unlucky to get a supercharged ep3 :P

    could be a/c compressor clutch, honestly there are several possibilities I would recommend seeing if you can identify the source of the noise and go from there.

    It happens on all gears and neutral.

    Clutch does not change it either....

    well if is not effected buy th3 clutch then that rules out gear box follow the noise and find out where is coming from... it could be any number of things and just random guesses on the internet aint the best way to go...

    the reason i posted this is that i could not find where the noise is from and would like some guesses from other car owners or if someone whos had the same problem before could help me out. ive been to a couple of mechanics and they didnt find where the noise ifs coming from and thought it sounds NORMAL.. it is not obvious if you rev and listen near the engine bay, but when your sitting in the car with windows shut you can hear it like whats in my video. The car has an aftermarket exhaust which i do not know what brand it is, could it be the exhaust? i doubt it though.

    Well we are gonna have a hard time guessing. But if it follows engine rpm and isnt gearbox related then look at pullys and tensioners..if thats not it then look elcewhere
