Flywheel Chatter

Flywheel Chatter
I think I'm a victim of the dreaded flywheel chatter, just started yesterday particularly when I'm accelerating. With the clutch dis-engaged the sound disappears, not a big fan of the sound, makes it sound like a rattle-trap.
Anyone else have this annoyance? Also it makes the noise at idle but much lower sounding.
I'm gonna drive the fawker harder just to spite it.

I think I confirmed that it is flywheel chatter, watch the video below that is the sound i am getting but not as severe it is very audible when I accerlerate though. You will be surprised to see what model of car is in the video.

Clutch, pressure plate, ring gear, clutch release bearing, even u-joints, may be the culprit.
I'd have a pro look at things ASAP.

OK chatter is usually from a lightweight flywheel very slightly being off balance, when your car is in neutral. But otherwise, I'd be worried about it being the bearing about to go out... according to the mechs I know, they've been known to go out on these cars, or maybe it was higher hp Nissans in general.

A little clatter is normal in neutral.
But clatter under load is a completely different diagnosis.
I would suspect the throwout bearing myself.
I've replaced them more than once on farm equipment, the sound is very similar.

My stock clutch was making a chatter under load, and so I decided to take apart the clutch to replace the bearing. I ended up changing out the clutch, flywheel, line... the works. From what I remember, it turns out the bearing was actually working fine, but had a bit of free movement, which I assume isn't too good either.
BTW, at least for the revups, the Nismo stainless braided clutch line is worthless... it's exactly the same as stock.

I posted this in the "G owners check your oil thread"
I found out last night that my 2004 6mt Coupe has this issue. I never thought to look at the oil as the car was mint when I bought it and I had an oil change right away on the day I bought. It had just over 100,000km. I have put about 8000km (4900 miles) on it and last night the noise was really loud as I started it up to go for a drive. I stopped immediately and shut it off.
I have a mechanic who lives two houses down and he came over to investigate. He said lets start with the simple things. Lets check the oil. We couldn't get a an accurate reading on the dipstick. We figured out the engine was almost bone dry. I was in shock. He then ran his fingers in the exhaust pipe after I told him it hasn't leaked a drop. He said he could smell the oil in the exhaust soot. I left the car exactly where I shut it off.
This morning I got 6 quarts of the Mobil synthetic and topped it up. I started it up and so far no noises. I have yet to take the car for a good drive. I consider myself lucky as the valve chatter was getting pretty intense, had the car been running regular oil I think the engine would have sustained some serious damage.
It also makes me think why the previous owner turned the car in at 100,000km. He\she probably noticed the problem and said time to get rid of it.
Moral of the story I will check my oil a hell of a lot more frequently 5.5 quarts down after 8000km or 4900 miles. I'm not used to this. I have a Mazda pick-up I have owned for 16 years and it is always rock solid between oil changes except for the last few years (259,000 miles 415,000km) and I didn't expect this from the G.

Now you need to check in at the dealer and fill him in on the issue so that they may do a proper consumption check for you.
If consumption is excessive, you may have a warranty claim.
G/L and keep us posted.
