I have a jingling/clattering noise in my engine at EXACTLY 2000-2500rpm, it's real quiet and faint when your in the cockpit of the NX, when you're driving around at 2000-2500, but if i step outside the car and have someone hold the rpm's at 2000-2500, i hear the jingling/clattering...what is this? it's not affecting my performance much, or, it doesent seem to. the car still runs the same. i have noticed this noise for a while, perhaps ever since i got the car, but have never really thought about it. what could it be? could it be my timing chain tensioner? if so, i have another one, should i install it? the procedure is rather easy, to install another one, right?

Do you have a header? Headers will make that noise.

 

[silversx]

nope, no header. i'm stock, 176,000 miles. i hear the timing chain tensioner needs to be replaced around 100k..

Does the ringing change with rpm. Mine does, sounds like a freaking chain.. Real faint though. Mine must need a tensioner. 115k original.

I had a ringing sound right before 2000RPM, we figured out it was some metal rings that were over a [now unused] EGR tube. Just so happened at that frequency they would jump and make a loud ringing sound.

I left it there. It adds "character" so says Luis.
