Are you having any issues that prompted the in depth look or did it just make a lot of noise?

I actually did a smoke test on the engine because I was getting lean codes on both banks. That led me to this. But I could hear a high pitched whistle when raising rpms too. So replacing the valve cover should remedy it? I'm planning on changing the eccentric shaft sensor too as I found some oil there.
