Suggestion
Nor fun, but if it were mine (C4S), I'd disconnect the CVs, pull the Cardon Shaft (I think that is what it is called) and front diff and put it on a bench.
Leading evidence: 'Disconnect cvs, pull the cardon shaft (i think' (no explicit attributable resolution; this is a reported action or suggestion).

These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

I have an 02 C4S with 87,500 miles that I have owned for a year and a half now and going through and updating maintenance on. Was replacing the transmission oil and front differential oil and the transmission went fine but the drain plug on the differential was on really tight. The front differential oil had been replaced several years ago by the prior owner and his shop really cranked the plug on. I got it off but when I went to tighten it on with my torque wrench it just spun and the threads in the case stripped right out.
Anyone that�s dealt with this and recommend a repair? There seems to be a few options such as a helicoil, time-sert, piggyback plug? It�s it a pretty tight spot which makes drilling strait in to clean out the hole tough plus making sure you don�t get shavings into the differential. And the plug is pretty large so not a lot of options for bigger plugs.
Condolences! I had a similar experience. Mine was super, super tight, too. I thought I was going to break it for sure, especially since it is hard to get at it squarely.
Not having been there to drain front diff, if no space for fixit-tools, get it out and on a bench.
Nor fun, but if it were mine (C4S), I'd disconnect the CVs, pull the Cardon Shaft (I think that is what it is called) and front diff and put it on a bench. I have a large set of Time-Certs, look to see what is largest or semi larger. Drain front assy and drill from bottom >>up., wax on drill bit. I have M12 and smaller Time-Certs, but there are larger sizes available. If I had to, I'd drill/tap it fine-thread english something or other and a common bolt.
The "piggy-back" idea sounds OK, but you are still at the "tight quarters" problem. Bigger size drill and taps are also bigger, so the "space problem" is still there. In other words, this is not a Porsche problem, it is a machinist problem.
Helicoil would not be my choice under any circumstance. I don't know if they are "leak-proof".
YMMV
I haven't made this repair, so take my suggestion as just a "maybe." I would be tempted to explore whether the bore for the plug could be opened and re-threaded for a larger plug.
