"tinny" noise when reaching 2k rpm

[JD]

i havea very tniny noise coming from the engine at around 2k. this doesnt matter whether i am in gear, moving, braking etc etc, so long as the engine is revving at 2k.

my first thought was that maybe the manifold is a little loose?

any ideas on what else it could be?

Tiny noise or tinny noise ?

If it's only at 2k revs it sounds like something must be resonating due to the frequency of the moving parts, dude. I'd get someone to rev the car for you and then have a gander under the bonnet, see if you can spot anything that way.

mine did this but around 4k and the fuel rail guard was lose

^ You can rev the car when your under the bonnet if you need to. Go have a checksies !

My backbox does it at 2k and then about 3.5k, i think the baffles are going in it.

 

[JD]

Not unless the 9 bolts have worked their way loose and the exhaust has been pushed back lol
