I have standard, modern, Shimano "cups" threaded into a titanium shell on my commuting bike. All parts are relatively new.

I tried a heavy application of blue thread locker and then about three wraps of PTFE tape (cups still screwed in easily) when that didn't work. The tape helped, but didn't fix it.
What should I try now, more tape? Is there anything else?
You sure it's not your crankarm bolts?
