What does it mean if my spark plug looks like this...
However when I took out one of the plugs it looked like this...

It didn't take as much force to undo this one either, so was it just loose and got covered in oil?

looks reasonable dry at the bottom so coming from the top?

It was oily all the way down but some of it rubbed of because I was putting the protecter caps from the new plugs onto the old ones as I changed them.
And the rubber part of the coil pack had a lump of congealed oil stuck on the very bottom of it too.
However using my CSI skills I could tell from the pattern of splatter (getting finer the higher it went) that at some point it looks as if some oil has sort of...poofed out from around the thread or something

IS 200 Sport with a few mods, Standardish IS-F. The IS250 SE-L with a few mods has gone to a new home.[SIGPIC][/SIGPIC]
It's more likely oil spillage pooling around the plug, and if the plug was loose as you say it was, the compression from the cylinder has leaked around the thread and caused the spray pattern.

What's the best plan of action then? Is it something I need to look at soon?
Or do I just wait and see if anything else happens that confirms thats what it is?
