You have had your valve cover bolt grommets replaced at one time for sure. So chances are, the gaskets have been done as well.

The mess you see up by your injectors looks to me like every other car that has cracked LIM gaskets. If it gets any worse, you will start to see coolant puddling around your injectors.

Easy fix...takes a few hours to complete. Basic hand tools, and new gaskets. Only thing you need that might be considered a special tool is a torque wrench.
