scan test for codes could be bad coil

just removed plugs and cylinder 2 was full with oil. coils were ok. What would cause the oil in the 2nd cylinder spark plug socket? Cleaned all plugs and installed them misfire seems to be gone for now. I would like to know how the oil got into the plug socket, and how to repair so it doesn't happen again. Approximate cost to repair would be appreciated if possible !
