Blackvenom01

I have a 01 cobra wit 48,000 miles when i first got it i did not notice this noice but when i get up to right about 3000 RPM there is a slight rattle just right there at that rpm. I thought that it might be one of my cats like a plate fell loose cause i had that same thing on my old mustang which was a 2003. I ended up gettin a bassani O/R x pipe and i still have the rattle. It only rattles when the car is warmed up. I am thinkin there might be some loose part and that that rpm and engine sound its just enough to rattle it. But i also have no clue wut it could be. If anyone knows of anything or any suggestions or it has happened to u before i would greatly appriciate a comment. thanks

Thats what my engine is doing in my case it is my motormounts there is almost no rubber left in the mount. I am going to try and change them out today with the engine still in the car. Ill tell you if this ends up being the only problem.

can you get an audio file of the noise, there is to many parts that could rattle. could be the mounts, could be a valve, could be a stupid *** bolt.


if you change your motor mounts while the engine is still in then please, get a video, i've never been able to change ANY engine mounts with the engine in the car.

i would get a vid of it but its not that loud of a noise that i can capture it wit a vid...u sorta need a tuned ear to that specific sound cause the exhuast drownds it out a bit....to me it just sounds like a loose part...

USMCrebel

could it be your PS fluid needs changing? or maybe a header/ manifold bolt loose?

i kno i hve a slight leak from the ps but idk why that would only make a noise when i hit 3000 no matter which direction...i just out on my x pipe so that is tight but i will look to see if a manifold bolt is loose to the engine...i figured i would hear air but the rest of the bolt could support it
