Hello about 7 months ago I got my 2003 350Z I don't know much about cars as a whole but I do need to ask a big question because today I heard a noise coming from my car when it is in idle or when I push in the gas when I push in the clutch the noise practically goes away I don't feel like it is Rod Knock but you guys can be the judge of this just need help and feedback

 

Regards, Carson B:

Z33's are famous (infamous?) for transmission input shaft bearing noise, a chattering sound. Research "Cement mixer" or "can of gravel" posts on the forum.

Incipient rod knock will be most evident when lifting the skinny pedal following acceleration.


Peace,

 

Normal behavior. Input shaft bearing noise and sometimes throw-out bearing. Nothing to be terribly concerned about. If you ever replace the clutch, check the input shaft for play, if it feels tight and there aren't any signs of the seal leaking at the transmission case, I wouldn't worry.
