If Loctite doesn't fix a creak it may not be the bearings or cups creaking in the BB shell. I have Gossamer crank in a FSA press-fit BB that creaked on the left crank down stroke, before 100 mi. Took it apart and realized it was assembled completely dry, with no grease between axel and bearings as seen in the youtube assembly video. Greased the axle with some heavy boat trailer grease and the creaking went away.
