The filament oozed out of top of the heating element. What would cause this?
Is that on a V3SE?
That looks like what happens when a blob forms at the nozzle

Yep, it is.
I think the connection between the hot-end heater and the connection within the heat sink is not tight. I am not familiar with this hot-end but most are either the teflon tube is not tight against the nozzle but more likely your heat break is not tightened against your nozzle. I had this issue when I switched to a Slice engineering heat break which tightens against the nozzle. In the long run I purchased a torque tool from them and tightened it up and all was well after that.
But before that I had to get rid of all the oozed filament, even on the threads at the connections. I found an odd trick. NOTE my filament was PLA. I soaked the metal parts in Acetone. It does not dissolve the PLA but rather breaks it down so that anything left over is like dust which can be wipe off easily after it is left to dry.

Thank you Howard_Anstedt, that is good to know about.
It is normal for a small amount of filament to flow out during the initial printing stage, but it should not be oozed out of the top of the heating element. This may be due to excessively high temperature settings or issues with the retraction settings.
