Well, today after my drive in to class I noticed a slight oil smell inside the car so I popped the hood. Sure enough, there was a little bit of oil that had leaked out of the valve cover and onto the exhaust manifold. I have never seen this area dry, ever, but now that it has started to smell I think that I should get it fixed. My question is how difficult is it to do and is there anything to watch out for. I wouldn't even be asking this question if it weren't for the fact that those sparkplug cylinders have to stay sealed good so that oil doesn't get to them. Has anyone had to do this on their own and, if so, how did it go? Were there any complications you could warn me of, etc., etc...
