First; Great pictures they help a lot!
To me it looks like oil all over the back of the engine from a mist under pressure like an exhaust leak. Common on a two-stroke engine or perhaps a four-stroke with an oil issue. Do you fog this engine in the fall? Even oil up on the head bolts. Is there a crack or bad gasket on the exhaust flange? You can even see the direction of the splatter from whatever source is causing it.
The smell and feel of the oily mess should tell you what it is.
And;
Do you have a carbon monoxide alarm?
