I think I had the same noise before I had my 100,000km service, got the belt, tensioner and idler bearings replaced. It was not a cheap trip to the mechanics that was origionally just supposed to be a tune up.

They said I had a serious timing belt noise and recomended I change ASAP. That was Gavin Wood Autotech on the Gold Coast so I trusted them and had it done.

Get the cambelt and pullys check. I had the same noise ...along with it sounding like there was a cricket living in my housing. Well I left it a little to long, snapped the belt and bent 4 valves.

The idle pulley had be refitted after getting the cambelt replaced (done when car was complied), some idiot put a washer behind the pully and this threw the allignment out. It ran the belt against the housing and wore it from the standard thickness of 1' down to a 12 inch thick.

I had my water pump replaced recently, and they needed to get the timing belt off. When they put it back on, it was way too tight, and made noises on idle once it warmed up. When cold it made no noise...

Also check to see if it the bearings on your A/C, alternator or power steering.

To do that, take one belt off at a time to see if it stops..

ok well im pritty sure its my cam gear bearings coz my dad said the same thing as u guys  said, where would i get it fixed is there a good place in melbourne?? thankz guyzzzzzzz

id say its you timing belt not cam bearings, they dont have cam bearings you can replace, they are just machined journals in the head and caps. i did a timing belt for a friends rb25 and before i did it was making similar noise to you were talking about, found belt pretty lose. After i replace the belt it was all fine. just my opinon from your discription
