Newbie here. Neways, couple of days ago my car started running really ruff. I figured it was an ignition problem. I replaced the plugs, wires, rotor, and distributor cap. When i replaced the last spark lug (one closest to the bck of the car) i noticed that the spar plug was all black. I also noticed that there was some fresh oil around the top front of the engine. Is it a bad fuel injector or bad gasket. I'm out of ideas.

It is probably your valve cover gasket leaking, mine was doing the exact same thing. It only costs about 20 dollars and takes ruffly 20 or 30 minutes to replace. Hope that helps you out. Make sure while you have it open to clean out the spark plug holes.

The valve cover is all you gotta pull off. The gasket set will come with 2 gaskets, one that goes around the whole valve cover and the other that keeps oil from getting into the spark plugs, which will look sorta like this 0--0--0--0. Hope that helps.
