I hear this "new" noise from around 1.5k rpm to 2.5k rpm..
sounds like it's from the passenger side engine compartment (i am guessing that's where the timing chain is)

i can only hear it when everything is off.. and i accelerate slowly (quietly)

is this normal? or is something worng with the chain tensioner (if there is one) ???

 

Timing chain is on the front of an engine(facing radiator), not on the passenger or drivers side.
Something else is probably the culprit.

 

i feel you man. after a few months of getting my car and modifying it, I've heard the same metal chattering noise everytime i begin to accelerate. I think it might be coming from the axle or tranny or something like that. but it paranoys me whenever i hear it...like something is about to break or come loose. maybe its a bolt or something?

 

I hear something weird on the passenger side at around 6k. It sounds like a whine and not a chatter. I have no engine mods though. Just a polished plenum. Debating on taking it to the dealer, but they never seem to understand anything about cars. You have to hold their hand and walk them through it.

 

i have an appt setup w/ the dealer today to test drive the car together.. hopefully they'll know what the problem is..
and it's actually 1k to 1.5k rpm.. and only when i am gassing the car..

 

i have the same noise, i think it's the heat shield.. i'm pretty sure.. i hear it when my windows are down on the passenger side and only when i hit the gas pretty good. post and let us know what they say thanks

 

couldn't reproduce it with the tech in my car.. we just deemed it as loose heatshield and left it at that.. lol..

the car runs perfectly fine..

 

It's funny how everything always seems to be fine when you show a tech. It drives me nuts when that happens.
