Engine Whine

[Edin430]

From time to time I get a bit of an engine whine coming from behind my head at low revs, mostly in first and second gear and below c.20mph.

It's sometimes not there at all, but then it's sometimes very noticeable (I wouldn't say 'loud').

Any ideas what it could be? Alternator? Belt?

Toyota 2zz Exige n/a 06 55.

Any oil staining around the gearbox? If it was a K series I'd say TADTS...

Nothing that I can see.... Will need to take a closer look in the daylight however.

Is it the same pitch whether you're in first or second? Anything that sounds like a whine I would normally put down to gearbox rather than engine - differential, perhaps?

Cheers,

same pitch regardless of gear however it gets loaded the more throttle i give it in first gear (until i can't hear it obviously)

anything to get checked out do you think?

Alternator maybe? I know they can get noisy when they're on their way out - mine made a noise (not exactly a whine) for best part of a year before it gave up.

All Exiges whine.............. (because they are not an Elise)

more testing tonight... first and second gear at low speeds when the engine is warming up are the worst - gets a lot better after a long drive.
