Spark Plugs looking a little oily

Hey all. I was wondering if any other vfr's have oil on the spark plugs. Not on the plug so much as the threads. I am new to the VFR motor but as I understand it, there is a rubber seal that separates the cams from the cylinders and sometimes this basket seal can leak. Under acceleration I see a bit of smoke from the pipe. Any thoughts?

 

how is the burn on the element? clean burn? how long have the plugs been in?

You know i just read some other threadds on the forum and found a lot of answers. I guess this is a common thing to see when replacing plugs. Think i learned to read more before i post!
