Hey everyone, i have a 2008 g35s 6mt 158k miles. i recently noticed a deep knocking noise at idle after driving around. has anyone else experienced this? i can send you a video on instagram if you are interested, thank you.

Be more specific; Knocking from engine or transmission? Top of engine or bottom or which side? Front or rear of engine? Does it get louder with revs?

 

it sounds like the bottom driver side of the engine, i don’t think it’s the trans. when i rev it the engine drowns out any noise and sounds normal

 

Post that video clip on here or use google drive or uTube.

 

jack the car up and grab a buddy to rev it up and see if you can locate where the sound is coming from.
