Fluttering/rattling reverberation noise! Pilot, throw out, input shaft bearing or something worse??

05 g35 6mt base. currently at 65,5k. no aftermarket additions. hey man. i replaced my clutch about a month ago (apx 62k) -- hearing EXACTLY the same kind of chattering/fluttering noise... as if a fan (thought it was the flywheel) or something was catching wind. at first the noise was significant when neutral-coasting.. but then would start up again whether disengaged or not. i took it to 2 certified mechanics who were just fighting for the work. one said the flywheel had to be machined and most likely clutch should be replaced (because essentially most of the $ is for the work of dropping the tranny n swapping everything out) the other said it was only the clutch that was burnt out...(which i still don't believe) and that the fly was perfectly fine. when i was looking for a resolve i came across a lot about the "throw out bearing" which is a cheap 5$ bearing that needs to be replaced whenever the clutch is exposed/changed... and the pilot bearing. both of these were completely rejected by the mechanics -- as the sole issue. so i ended up replacing my clutch, at fucking 62k, and haven't heard the noise until NOW. i know, 100% that i didn't burn my clutch, and from past experience ...driving it WILL make it worst. good thing for me its fuckin new years and i won't be able to go back to the mechanic for a few days. but i'll try and keep posted--likewise would be appreciated. btw dave.rodriguez2@gmail.com is my email

Did u ever find a solution to the problems mentioned above? Just wondering. Have an 01 crv makin the same kinda noise n dont want to have to replace unnecessary parts.

Check your oil level. Make sure you have the recommended five quarts in the engine. My car was making a rattling noise during acceleration and it was due to low oil level.
