04 spark replacement (does this look bad)

Just pick up the 4runner last week with almost 70k on it. Figured I would replace the spark plugs on a guess that they would the original plugs from the factory. Pulled them out and they all looked like this. To me that seem to be real oily. Is it me or should I be worried. The truck runs fine, oh and it is a V6

Doesn't look that great according to NGK's guide (first one I found with Google). The 4th gen V-6s call for new plugs every 30k using since they're standard copper from the factory. Somewhat of an anomaly since most vehicles these days, including the V-8, come with 100-120k rated irridium plugs. Change 'em.

Overall the plug looks pretty good if they truely have 70K on them but what concerns me is that the threads look unusually wet. Do you have a valve cover leak?
 
Mine had oil on it as well at 30k. It wasn't completely wet, I'll try and get pictures of them. They've been out for about a month and half now.

I'll be pulling the ones from my Taco pretty soon. I'll pics of them when they're out.
