Threw new valve cover gaskets in, did the passenger side a couple weeks ago when I had a few spare minutes, and then the drivers side before the disassembly of the oil pan. Was having a weird little oil smoke under certain driving and figured it’s been close to 75k since the valve cover gaskets were replaced. Can’t believe how easy it is to swap out valve cover gaskets on these engines. Put new rubber grommets on the valve cover bolts as well since the came with the new gaskets this time around.
