I removed the plastic protector and it looks like it was melting from the hot gasses leaking next to it.

Here's a photo of how it looked after a 3-4 mile warm up drive after reinstalling the injector today. The black stuff was not there before the drive. It looks like oil but I guess it could be residual spilled fuel or degreaser making its way out. The leak is definitely exiting between the head and the prechamber ring with a distinctive chuff-chuff-chuff. It still seems to fire OK and the engine does not run rough at all.
