Not OP's issue. Oil around plug went into the cylinder when he removed the plug. Causing the blue smoke. Common problem when the valve cover seal at the spark plug hole starts to leak.
You can also get blue smoke from bad valve seals and guides. Also from a bad pvc valve. Older transmissions that use a vacuum modulator. When the modulator goes bad. It can suck up transmission fluid. Causing smoke. Older GM's were great for this.
