Had a stud pull free while reinstalling the sump cover ‘73 911E. My torque wrench was set at 8ft/lbs, so I was surprised when it kept spinning. I did notice some silver in the case-side threads that maybe old helicoil?

I also have 1 to 2 other studs that may be spinning.

Some other posts made it sound like these studs spinning is somewhat common and to just reinstall/replace and add red locktite. Others suggest tapping and using a new m6x1.00 helicoil.

Thanks for any help!
