Engine I'm hearing things...

i see dead people but you don't see me complaining!

i think i know what you are saying.
it practically sounds like something is not tight enough from the exhaust pipe and makes that noise yet you don't know what it is right?
i had a similar problem when mine was lowered, till i hit a bump really hard and it went away. that is NOT my suggestion.
you can lift the front end of the car, take the wheels off and ofcourse secure the car (somehow), and have a couple of your friends try narrow down where it is coming from.

I'm hearing things...

and I can't figure out what it is. It's a 99 VE 5spd with 140K miles. I know the ball joints are bad and my CV joints are on the way out(and I know what that sounds like). This sound is more like a rattling or chattering kind of sound. I have loosened and tightened all the exhaust heat shields, exhaust manifold, intake manifold, engine cover, and just about anything else that I could see that could be contributing to the noise. I have found that if I keep it at a certain RPM that it can get really loud(I don't know what RPM since I don't have a tach ) I am just looking for any suggestions on things to check. I don't want to just start tearing into it or replacing things until I find out what it is. I'll take it to get diagnosed by a mechanic as a last resort if I have to. There are no performance issues that have accompanied the new sound either. Thanks for your help!

So you're saying it doesn't matter whether the vehicle is moving or not, it is totally dependent on what rpm the engine is at?

If I have it parked and the hood up and I rev it from the throttle body I can barely hear it. While driving down the road I can hear it a lot better. When I get to a certain RPM it is really noticeable and loud. You can hear it at all speeds in all gears but it isn't as pronounced as if I were to get it up to that RPM and hold it there no matter the gear. Hopefully that helps clear up any confusion. Thanks!

You know how when you go to take your car in because you are hearing something funny or the car is acting up everytime you drive it, but when you take it in it runs like it just came off the showroom floor? Well, ever since I have been trying to pin point where the noise is coming from the noise has stopped. I haven't changed any driving habits or anything. I will post up once it finally starts doing it again or I can inspect a few other things in the coming week or two when I can get a chance to look at it more closely. Thanks for the help.
