Hey guys, today I finally swapped plugs to NGK Iridiums and I discovered oil down cylinder 6's spark plug hole. Did some searching around in the forums and found that I wasn't the only one to have this happen to but the fix I keep seeing is a new valve cover because Infiniti doesn't make a replaceable gasket?
So I did some more research and found that the Nissan line of cars have replaceable gaskets for the same issue we have so now I'm confused why we can't do that as well. Without actually having a valve cover off the engine I can't really picture and understand why this is the case.
Has anyone actually looked into this without rushing into a new valve cover?
As far as I can see, the spark plug "tubes" are park of the upper engine camshaft and there's a gasket in the valve covered that seals the oil out. Maximas seem to have the same design, so i wonder if their gaskets would fit ours or any other line that Nissan\Infinit makes.
If anyone can enlighten me on this topic, that would be awesome. Tomorrow I'm going to see if I'm covered under warranty before I go any further into fixing it myself.
