Hi,

Today while parking my car, I thought my engine noise is not as normal as usual, maybe I'm paranoid so I ask you to tell me if you think the engine noise is normal or not.
The engine has run for about 10kms (about 6 miles)

Here is the video, click

Don't know what to think...

Thanks for your help!

Edit: Stock engine, only HKS catback

 

bump!

21 views and no idea?

 

What kind of sound is it making? What does it seem like to you - tinny, pingy, clangly, like it's dragging a chain, something else? Based on the video, it sounds normal to me. Maybe get a mechanics stethoscope (the one with the probe on the end) and you maybe able to find out where the sound is coming from.

 

When did the noise appear? Did you just recently install the catback? I can't hear much on the video that sounds weird except for perhaps an air leak of some sort or perhaps the beginning of the card in the spoke sound that is usually a TCT going bad.

 

Hi,

Thanks for your both answers, it seems to be normal following your opinion.
The sound I hear is cyclic, a kind of yooooonnn yooonnnn yooooon.
I cleaned IAC and tested PCV valve (which was totally ok).

The catback has been installed 2-3 months ago, but maybe the wall next to the driver fender is amplifying the motor sound so I think I have "a noise"

I didn't pay attention until yesterday in fact

I think this car is going to make me paranoid as I want to it to be perfect
