What the heck is this?

Water in oil saga continues. I'm about one inch from pulling the A4.
In the meantime I run a compression test and pressurized the block. I don't have confidence in either test yet and will redo. I pulled the valve cover off. Just to the right of the right most valve? What the heck is it?
Note I can't see directly so took pictures with flash on
