Strange rattle in back of '01 986S

[heymanwatchthis]

PorscheBound,

Here is update on my car - in summary I think we may have similar issues. My concern was rattling from back of car on accel/decel. I replaced motor mount assuming the rattle was from engine moving around. This definitely helped but some of the rattle is still there. After replacing the engine mount can still detect some shudder, mechanic says it is the clutch shuddering a little at engagement. I also notice clacking when car is idling with clutch out, does not happen when clutch is in. Previously I thought this was nothing to worry about, but with the clutch shudder and this sound it may point to dual mass flywheel issue. I changed transmission oil, still does it, only when the car is hot.

The clutch/IMS was replaced in March, my mechanic wants to open up tranny to see if something was not torqued appropriately, if there is a flywheel problem, etc. In the meantime mechanic recommends NO autocrossing until this is sorted out. I am dropping it off on Thursday will let you know outcome.

Do you still experience the rattle when idling in neutral?
