Mine does that. Can see the oil weep but no drops on the ground, only tacky film from the oil. Did a short term patch, figured I would pull that cover off at some time and correctly seal it. I pulled the wire out of the keeper and used 2 zip ties. One on the boot and the other lower to keep it bundled with the other wire. Lets the rubber boot bend more to its shape rather than being pulled almost straight.
Here is a pic
