      You may have worn valve guides where oil is seeping by into the cylinder. Could also be worn cylinder rings. Have you done a leak down test on it?

      Also possible that one of the seals on that cyl. got dislodged.

      Thanks – I have not done a leak down test.
      The car is only at 8,000 miles – is seeing this common for this age?

      With 8K miles, it shouldn’t be. Do you do a lot of hard braking? #2 Cylinder is the first up front on the passenger side. I would say have a leak down test done. It will tell you a lot about each cylinder and then you go from there. Leak down test is fairly easy and cheap to do. If the results come back good, then you may have a simple issue.

      could it be an injector issue as well ?

      Would be gas, not oil.

      I replaced plugs and wires recently.
      One of the plugs had what appeared to be (and smelled like) a slight amount of oil on it. Not dripping, but definitely a bit wet.
      Any idea what could be causing it? The wet plug was in cylinder #2.
      Thanks!
