Hey, so I just got a 350z a couple months ago
I replaced the original clutch and flywheel (dual mass or something i think right?), with aftermarket ones. Put in an exedy clutch kit and an act prolite flywheel.

Now I noticed when idle (clutch pedal not pushed in, in neutral) there is this rattling/clicking/grinding sound thing coming from the engine. I assume this is normal because its not a dual mass?

Also, it sounds like a truck accelerating :/
but other than the sounds its works fine.

Do you know what could be causing the rattling? My friend thinks a lose throw-out bearing but I'm not sure. My mechanic says the sounds is normal/fine since I went with aftermarket parts...

The rattling and grinding sound would be flywheel chatter from the lighter flywheel. Lighter flywheel = more chatter

The question is asked often and the answer is always the same. Aftermartket flywheel-clutch is not made for for the average driver. It makes all sorts of strange noises.

very interesting info..i am in the market for a new flywheel / clutch...how loud is this chattering? is it so loud and annoying the girl in the other car cant hear a single word im saying?

Ah I see!

Haha I guess I will!

Well thanks for the info guys.

david79 - It's not that loud, I'd say perhaps up to par with the engine idle, although a little louder. I'll see if I can record the sound on my phone for you if you'd like :/ But I will say I do like the feel of the aftermarket parts I put in over the stock, not as stiff Sound is just annoying but eh, my girl can't hear it inside the car so oh well!

Light weight flywheels have been doing this for the past 6 years now, there is even 6 years of people complaining about it on here too.

does anyone know, when changing the clutch do you have to drain & refill the tranny / diff fluid?
