Just wanted to post an update, if anyone is ever curious.

I ended up thoroughly cleaning off the anti-sleaze I had applied, and instead I placed some blue thread locker on the threads and inside the cup where the edge of the BB mates with the cup (there is a little washer there).

I tightened the non-drive side pretty firmly and let it set overnight, and then installed the drive side. No spinning of the opposite side at all, and was able to torque it down to 70nm with no problems. Interestingly, when I then put the torque wrench on the NDS, to make sure it was also tight enough, it didn't turn at all before the wrench clicked, so I guess the pressure of the drive side pushing back on the NDS was enough to make it tighter as well.

So far so good and I'll let you know how it rides. Despite being used, this BB spins SUPER smooth when you mount the cranks, and it looks happy to spin for a long, long time.


PS. Blue threadlocker from loctite now comes in a red tube. WTF?! Thank god my GF was with me at the store, because I was already saying, "just my luck, they are out of the blue..." When she pointing out that some of the read tubes said "blue" on them. Why?
