Big Supes Posted December 10, 2008 Share Posted December 10, 2008 the light goes off straight away as you can see in the video, i didint think it sounded like it aswel, could the autobox make this sort of noise maybe, but how about when ive put it back in to park? reason i ask this is becasue as i said in the earlier post i can jump in the car and start up, sit there for as long as i want and it does not do this noise, it only does this noise under load/select drive and go. i still think its exhaust gaskets around the manifold/turbo. It should be pretty easy to diagnose a exhaust leak around the mani/turbo. It would be a "chuffing" noise and you should be able to hear it from under the bonnet. It's a tricky one to call from hearing the clips. If it was a timing/alternator/AC pulley, it should be more consistent and wouldn't necessarily go away once it's warm, but it might still be worth look at them to eliminate them. You NEED to get under it and have a look matey. Just hope my first suspicion doesn't come to light. Link to comment Share on other sites More sharing options...
Fearless Posted December 10, 2008 Share Posted December 10, 2008 Recently had a leak on the power steering hose so Power steering pump was low on fluid and it sounded like that and it could explain why it only does it after you have driven it a short way and probably turned the steering wheel.

supraGZaerotop Posted December 10, 2008 Author Share Posted December 10, 2008 thanks for the idea, i checked my power steering fluid the other day, its full. il have to leave the car up my mates garage so he can sort it, its a strange one tho, Link to comment Share on other sites More sharing options...
madwoody1 Posted December 11, 2008 Share Posted December 11, 2008 i have that same noise it goes away fairly quickly, now the thing i thought it was was something to do with the turbo having some play in it and as it gets hotter the metal is expanding so taking the play away what sort of revs does it come in at? if its 2000rpm the thats about when your turbo starts to spin?

(i think) spot on mate, does start making that noise @ about 2000-2500rpm, youve got me thinking now, i wonder if it could be the turbos:( it is around that mileage 83000miles Link to comment Share on other sites More sharing options...

Axle Posted December 13, 2008 Share Posted December 13, 2008 Mine oddly enough has started to make the same kind of sound. To me, its like exaggerated turbo flutter. I doubt its the Turbo's. I hardly drive mine, and it has a little over 40k on the clock. So would be surprised if it was. Sometimes i dont even hear mine all the time. Well not yet anyway.

R Black Posted December 13, 2008 Share Posted December 13, 2008 I have the same sound, can only hear it inside the car withj the passenger window down, i read some noise points a while back, which seemed to point to injectors. My noise starts after 2k also, however its not always present at start up or after a run??? Link to comment Share on other sites More sharing options...
madwoody1 Posted December 13, 2008 Share Posted December 13, 2008 might be the cat having movement until the insides stop expanding once theres heat in there? Link to comment Share on other sites More sharing options...
Axle Posted January 31, 2009 Share Posted January 31, 2009 Did you ever find out the cause of the noise to this? Link to comment Share on other sites More sharing options...
Guest Luigi Posted February 1, 2009 Share Posted February 1, 2009 (edited) Sounds like a direct drive from the engine. See if the cooling fan is rubbing anything and then check for loose or broken eng mount, which can let the eng move around with torque when accelerating. Have someone watching when you give it the juice. Other than that maybe an idler pulley brg on the front, or loose/torn drive belt.

ManwithSupra Posted October 8, 2009 Share Posted October 8, 2009 Did you find out what was causing this noise mine is now doing exactly the same. Link to comment Share on other sites More sharing options...
kaahari Posted October 9, 2009 Share Posted October 9, 2009 I got quite same broblem about a week ago. Strange sound about 2000rpm. It was leaking gasket between midpipe and catback. Took some time to find it, when driving, it sounded like it`s coming from engine... Link to comment Share on other sites More sharing options...
loks Posted October 9, 2009 Share Posted October 9, 2009 Had a very similar noises that I believed was coming from the engine and would disappear once the engine was kinda warm... mine turned out to be the catalytic converter (2nd one) in the exhaust, which was breaking down internally and parts were "vibrating" when cold but when hot (fully expanded) they could not then vibrate. Easy fix... removed the damn thing with a straight through pipe... viola noise gone. Link to comment Share on other sites More sharing options...
