symptoms of failing flywheel 2.4 jtd?

I had previously posted a day or two ago asking about solid flywheel conversion kits but thought I would explain my problem a bit more in case it may not be the flywheel....fingers crossed.

I have just bought a 2.4 jtd that previously hadnt been running for a year, it is now going but there is a rattley/vibration noise coming from the passenger side of the engine bay, and when you press the clutch pedal in it goes away.

My question is does this sound symptomatic of a failing flywheel or more likey a release bearing etc as it has been sat about a while? The previous owner said he had noticed anything up with it when it was going a year ago.

The car has 102k on it and had clutch/flywheel change at 60k and no other sysmtpons like juddering, clunky gearchange etc and appears to be good bite with the clutch etc

I would guess not the flywheel, possibly something on the gearbox side, as when you press in the clutch it stops.
My guess anyway, anyone else got any thoughts on it?

if the clutch and flywheel were replaced only 40k ago then my bet would be its neither of those things causing your problem. unless its been remapped and then driven hard all the time then it could very well be.
As mentioned it sounds gearbox related, whats it like to change gear? its not suspension related as you mentioned it goes away when the clutch is engaged. When its the DMF thats failing you will have vibrations when the car is idle aswell or if not a simple test can be done to exclude the DMF, with the clutch both engaged and disengaged rev it slightly from 1000-2000rpm it should start vibrating between this bandwidth, if no vibration is present then i would look at the gearbox, recons arent that expensive but its a pig of a job.
Hope this helps

The vibration part seems strange especially if your talking about at idle and not driving it.

Rattling with the clutch disengaged could be the release bearing, but if your revving the engine and there's vibration that goes away when the clutch is depressed then get it to a specialist in case it disintegrates and causes more damage, cv joint/s could be causing the vibration, get it checked out professionally.
