    I drive a stock standard Omega auto VE MY09 built 08-09, 3.6L unleaded fuel.

    I've had it since Feb 2013 and its done a 116+ks. last outing or two I have started to hear a whirring sound that is directly related to revs. I can now, only just, hear this when I'm going along the freeway. Before I only heard it at idle and thats been going for say, the last 150ks around town over a couple of months or so.

    is it the timing chain?
    if it is how long might it last for?
    how much noise does it have to make before it shits itself?
    if it shits itself i spose it will just stop then and there?

    whats involved in fixing it?
    what are the key things to know and do?
    roughly how long would it take a mechanic to fix it?
    Is it the kind of thing I could do myself? I have a fixit book for it.
    should I fix it or ditch it?

    I've got a good half inch socket set I've had for 30+ years, I got a 10mm plastic one from Bunnings for xmas one year recently, a 1/2 inch and a 3/8 tension wrench, a lunch bag full of open enders some of which I've had for 30 odd years some screw drivers and an 8 inch shifter.

    Appreciate all help people, thanks

    A video or sound clip would help.

    I dont think its the timing chain, they make a more clunk Metal rubbing on Plastic sound not really a whining noise. My car, before I got my chains done, didnt make a noise at all. It makes more noise now, after I got the chains done lol.

    The whirring noise isnt coming through the speakers are they?
    I have a faint winding noise, I dont hear it if the windows down. I think is related to my gearbox, hoping a service will help.

    It could just be a idler or tensioner pulley issue.
    Is it worse when the AC is on or when turning the steering wheel?

    You could try to remove the accessories belt and run the engine for a short period of time (do it cold, as you won't have the water pump anymore) and see if the noise goes away.

    Could it be the wheel bearings? I am having the same problem. It sounds like a squall of wind when i accelerate. only up to 50 kph. no metal rattle sounds

    this is the most likely culprit.

    Good thoughts, but no, now you mention it, it seems to occur at idle and going down the freeway on the low sound surfaces but it does sound like a power steering noise like the very early after market power steering add ons made.

    It does not come on as soon as I turn the engine on but pulled up at lights I can hear it at idle.

    Thanks, if its not the timing chain then I spose the idler pully becomes a good suspect.
