I popped opened my hood to help jump start my friends car and heard a vaccum hose was unplugged, its the hose that connects to the bottom of the hose that links the y-pipe to the MAF. so i unhooked the hose from the y-pipe to fix it and noticed that there was some oil at the bottom of the pipes. i am pretty sure that its from my valve cover gaskets because when i changed my spark plugs a month ago, there was oil within the threads. What do you guys think?

 

It's kind of normal for some to be in there, the breather that connects off the Y might need to be replaced, if you pull that off, you should see more gunk in there.
