Hey guys what’s poppin it’s ya boi haha. I have 2004 g35 coupe auto with 119,000 miles. Anyways I’m replacing valve cover gaskets on my g since I have a pretty bad leak that smells like oil when I step on it or been driving for a while but I also will be changing out spark plugs with brand new iridium ngk ones. Ordered some intake manifold gaskets that come with plenum gasket as well. Is there anything else I should do while I’m in that deep? I’m installing a catch can and sanding the inside of the plenum so that it’s oil free and cleaning the hell out of everything I’m taking apart. Thanks in advance guys, appreciate it!
