new whine from engine

[rev-tech]

hey people,
the Prelude has recently had it's 100,000k service so had a new timing belt fitted.
The guy who did it is a honda specialist, and he said he "tuned it up a little"
Now it definately feels slightly more responsive in the lower rev's and it's got a whine now (like a gilmer/supercharger)
Just wondering what could have possibly been done to cause this?

[fusionprelude]

loose belts maybe

[vtek]

or even a over tightened belt.

[Brash22]

Check the adjuster pully. May be too tight or too loose.

Does this happen in all gears?

rev-tech ur gona get a million diferant ideas what it could be on here and even with all of them theres still a chance no1 could get newhere near what the problem is cause most ppl arent mechanics and even if every1 reply was a quallified mechanic that had do nothin but work on prelude of exaclt the same model and setup of urs their not there to see and hear it for them selves.......bottom line man jsut take it back to the guy ans ask him.....and if you dont trust him take it sumwhere else and see what they have to say

i was with a friend test driving a 4th gen vti-r which had its timing belt changed recently and it had a similar whine, i think its normal...hopefully :P

[mr_mojo02]

most common cause is an overtightened belt, but as said, take it back to the bloke and get him to have a look

hey mine whine tooo....i have trace the whinning sound out..its at somewhere around the manifold area where it whine the loudest...which part of ur engine whine???

[rev-tech]

hey guys, thanks for the replies.

mattsama, yeah it happens in all gears, it's related to rev's, the higher rev's the higher pitch the whine.
hurstyboy, the guy who worked on it lives next door to my mum and is a honda specialist. Will have to ask him next time i'm over there :)

[marcus]

gosh if u the higher u rev the higher it whines it could be the gasket

[hurstyboy]

good to ehar man......i just wish i ahd sum1 like that

[grnlude]

this is normal I think. I have it on mine as well when I had mine done at 80 000k...

[marcus]

hmm...i nt sure if mines normal..everytime i start the engine 20-30secs later the sound appear...when i turn off the engine abt 5sec later the sound gone...my prob is somewhere around the intake manifold area,some say it the alternator...some say its the iacv...but if the alternator and the iacv is spoil, the car will not start or will break down soon...hmmm.....i brought mine to a few mechanics and they cant solve either

[Mav1]

oooh.. I have this "noise", too.. and I also got it after a timing belt change. If someone finds a "cure" for this.. definitely, post up~~

[ECU-MAN]

cure is to have the timming(s) belt retentioned

over time as they streach the noise will go away.

[vtek]

its not normal for it to whine.

[scottyj]

a lot of 5G owners mention this - especially in 4th gear... and yes it gets high pitched as correlated to revs... sounds like a mini supercharger.... it seems to happen a lot (there are a few threads on prelude australia.com re this too..)...

i'm not saying that if it happens to lots of people it is normal.... but it does suggest it might be 'ok' or at least some common....

[bigjo5]

yeh i think the timing belt is overtighten..

[marcus]

mine whine tooo but around the intake manifold area

did you install a jackson racing super charger by any chance?

[shecomb]

did you install a jackson racing super charger by any chance?
