On the business end of the plug.

Wet, oily deposits. Will cause weak spark and eventually misfire.Fault: worn bores/piston rings or valve guides; sometimes occurs (temporarily) during running-in period. Plugs can be re-used after a thorough cleaning. For Pictures.

On the outside of the Plug. Oil would be from a Leaking Gasket or Seal.
