It seems as if combination of UDP, 996 TB and maybe 997 engine mount of recent changes is causing some kind of isolated system instability that the factory ironed out, and it woke up this noise ghost?  |
The clutch in making the noise go away seems to be pointing to your throw out bearing or perhaps a rattle/vibration in the release arm or spring.
As an aside, I had all sorts of fits with shifting in 1st gear making horrible vibrations until I replaced the single front engine mount. It's a cheap fix easily done in your garage.
