I can swear Waldig had a DIY up before but when I search valve cover I get nothing good. Weird...

The tapping in my driver side engine has gotten loud and horrible... I want to pull the cover and, uhm, look around I guess.

Are there any pointers out there? Can't be that hard, move some lines and remove bolts but I guess my biggest question is what to use for the gasket afterwards and if the top valve recirculation cover has to be removed first.
