Finished up valve cover gaskets, again. Did it about 3 years ago. Oil started leaking on the backside of the drivers side valve cover. Took it apart, the eccentric sensor in the back was barely hanging on. The inside valve cover half moons were broken as well.

Replaced the valve cover, gaskets, and sensor. No more oil leak. I must have did some damage the last time I did the gaskets. Such a PITA not much space to work with
