OK, I pulled the front 3 plugs (the ones that are easy to get to

). They all looked OK at first, but then I noticed the middle cylinder plug seemed to have oil build up on the OUTSIDE of where the washer seals against the head. Attached is a link to a pic. Im not sure if this is normal or not, so I figured Id ask here. Also note that the middle cylinder in the front is the only one that does not have a shiny clean head surface where the plug goes, and the spot shown in the picture is only one part of the plug, the buildup is around the whole plug itself just above where the washer is.
Does this indicate that the cylinder would leak compression out of this plug?
