I noticed the other day that one of my two external cup BB and cranksets just had a hernia and some of the baby blue grease has gotten past the outer seal. Is this something that others have seen? It's the left side and occured at the outer edge of the face seal.
I love the high degree of stiffness and low weight of these one piece crank and external BB's but it sure seems like the seals are whimpy and exposed to a lot of side shearing forces from even careful installation. Mind you for all that the seal that went in this case isn't one that was disturbed at all as part of the install.
