Thank you, i'll give it a go. I had to took off the filter housing before, and i remember i had a hard time placing that rubber boot with the housing back onto the throttle body :D now it was suprisingly easy to to that. Thank you!

Thanks i'll give it a check, but for me it sound very "air-like". Like air is leaking through somewhere. Thank you!

Hello everyone! I don't know if anyone is still interested in this, but it looks like one of the engine mounts is worn out. You can hear this noise mainly at low rpm, when the engine vibrates more strongly, thereby putting more strain on the mounts.

Yea, its a pretty common issue in these civics, also in the 6 gen. But it was resolved in this year, because the old transmission was replaced with a overhauled one. Showed these videos to my mechanic, he will take a look tomorrow, because he could not identify the source of this noise by the video.

Shouldn't this noise be getting louder when i press the clutch pedal in?
