Hi everyone. I just did a tune up the other day on my car, and when I pulled the plugs out, there was oil on them. I know this isn't normal.....what could be causing this?

 

I saw the samething on my car. Is it where u pull the plugs out and there is oil on top of the spark plug or when you take the sparkplug out?

 

Its most likely the rubber seals in the valve cover. They go on top of the tube around the sparkplug. As they age they get hard enough to bounce off a concrete floor or at least mine did. If you go to Advance Auto or Autozone, don't remember which one had the part, if you buy valve cover gaskets it will have them inside. All you do is pull the valve cover off there they are in plain sight. Just pull the old ones off and put the new ones on and go ahead and put that pretty new gasket on there will your at so yours don't blow out like mine did. By the way you may have to dig the old gasket out of the valve cover mine was stuck in there pretty good.
