Can't think of a good thread off hand, but from memory the bearing on the torsional damper was installed backwards from factory. So the oil couldn't get into it to lube it.
If you do a search for output or torsional damper bearing you should find info.
There's an update kit you can buy but it's only really the bearing you need iirc.
I did my 06 engine a good few years ago, would have to dig through detailed files.
Before going any further would you be able to determine if the noise is from the front or back of the engine?
Presume it's on the left side anyway. Tha's clutch (front), trans (middle) and torsional damper output (rear).
