Whine on acceleration

[Weegie182]

Hey all,

Sorry to write another Clio Sport faulty mechanics post but... on acceleration above 3k or so in the rev range there is a rather high pitch whining noise - (the whine sounds almost like the BMW Cooper S if you have ever been in one?)

It had its aux/cam belts changed last year and has just had £850 on a service/MOT spent on it today (ouch!!) I hoped after bringing it to the garage's attention it would have disappeared when collected tonight but unfortunately not.

Is it maybe a badly/too tightly fitted belt somewhere?

Not a mechanic by any means so in layman's terms if you please :star:

Thanks

sounds like the diff m8 ,mines currently being done due to that noise...new gearbox time a video may provide a better diagnoses

Cheers for the post Seany

Ok i'll try and get a video up soon as I can.

I certainly hope it's nothing to do with the gearbox - I have it refurbished last year and the clutch replaced after a problem in the 2nd and 3rd chambers!

Are you sure it was "fully" refurbished? I bet it was bearings and synchros only and they missed the diffs crown and planetry gearing.

Hairline crack in the cat flange if it only happens at high revs like a high pitched whine ?

Does it do it if you rev the engine at standstill?

When i had the 1.2's cambelt changed it was slightly over tightened which caused it to sound whiney on acceleration

Hi Davo - on further inspection it actually does it throughout the rev range, not just a the high end as I wrote initially... And yeah it is like a high pitched whine. I will post a video on it in a second- see what you think

 

[Weegie182]

Yeah it does. The video I am posting is taking at a stand still (this will become obvious when you notice the bonnet is up... )
