Noise from Engine bay?

[vupham]

Hi guys, just bought a 04 jazz vti-s automatic. I noticed when i ifrst start the car, warm it up untill the cold icon is gone, i drive it and when i go pass like 3000rpm, i hear this rattling noise from the engine bay and it seems to go away when i hit 5000rpm, its more from the engine as i press on the eceleation as well, after a long drive like an hour or so, it goes away. The noise is like a rough rattle noise, not very loud but can hear it, What could be the problem?

can be anything really, headers leaking, cam timing is abit off.

does it sound like something lose or metal vibration?

more of a metal vibration from the engine because i can hear it as i press on the ecelation and stops when i left go, doesnt make the noise all the way, just a little bit between 3k rpm - 4krpm. It complete goes way after a an hour drive or so.

check for exhaust leaking or cracked headers or gasket leaking

it maybe the noise coming from your heat shield extractor - sometimes it happen if you are running aftermarket extractor... Sometimes my car make that noise too... take it to a mech...
