Last week I noticed what I thought was accumulated dirt just below the rocker cover. Like a fool, I wiped it off so didn't have the proof to send you guys a picture.
However, I've left it a week and this morning I took this photo to try and help get a diagnosis from you.
It feels like oil and although there's not a 'stream' of it coming out, it must mean something that oil is present.
Is this something that needs attention pronto or is it 'normal'?
What is it and what should I do to remedy it?
Your direction and help would of course be most welcome. Thanks folks.

Here's the offending article, it just seems to be on this side.
