Hi,

I have a 1996 Integra SE, it has 75 000 miles, I had the timing belt and waterpump done 5000km ago, factory motor, only modification is lowering springs, i have this noise right now, it sounds like a screw rattling around in a tin can, it happens at exactly 1350 RPMS, and only that, its the only time i hear it.

 

its your heatshields.. either your cat (which 98% of the time thats what it is that you hear ratteling) or your header heatshield.

but like i said. 98% its your cat heatshield. alot of people just take them off. or if your worried about running over a plastic bag and it melting to your cat. leave it on and tighten it if you can.

if you have a friend, or someone you know that lives by you, trustworthy mind you. have them sit in your car, rev it up to 2k.. and you lay down on the driver side and look/listen at the cat, i bet you thats what it'll be

good luck

 

its most likely a heatshield, but it can also be your valves. If you remove the heatshields and still hear it, see if its coming from the valve cover

but valves make more of a ticking noise, not a rattle.. right?

depends if you have ever heard an old car start up in the winter you could swear its a heatshield rattling but its the valves

Thank you all for the help, i will let you know the results after tomorrow
