In the last couple of months, two of us have had the same problem...the cheesy little red rubber cap on the Zerk fitting came off of one of the fittings on the prop hub, and the damned thing leaked a bit of grease which was then faintly visible on the canopy after landing (and on the cowling). It's not a big deal, but a PITA to decowl, remove the spinner, put a new cap on, recowl, clean everything up, etc. AND, we've had other friends who have had the same issue in the past.
It's not a huge deal, just an annoyance, but...*why* do these things leak like this, and (more importantly), is there a better Zerk out there somewhere?
