hey everyone. i'm not new to installing headsets with the right tools, but recently, i used some DIY tools to install a Tange Levin threaded headset on one bike and a Tange passage threaded headset on the other. anyway, both are leaking grease here and there from the bottom cup. i always try to pack bearings with as much grease as possible to avoid issues and this is normal for some spillage to accure post installation, however, both headsets are gritty already. the bearings sound like grease and sand mixed up inside. the headsets are both adjusted properly with no play, but they still got contaminated. i used some old grease from a phil wood bottle that had started to separate a little i think, but seemed good still. i considered maybe it was because the tange passage is so cheap that there was a break in the seal somehwere, or a defective crown race, but why then has this happened to both headsets? they've both been installed only in the last couple months. maybe the grease? i dont know. i know a gritty headset isn't much to fret about, it's still functional, but just an annoyance, especially since they're so new and i would like to not have to overhaul them right away like this.

thanks!
