Plenty of evidence of plenum problem

Let me clarify. The butt end of the thread as it transitions down to the electrode had what looked like a chunk of ash i think. With as much oil that was on the plug it made me think it was more like sludge but i'll have another look. It was coated pretty well with carbon on the rest. I will pull the TB to get a closer look in the plenum and see if i see more oil in the back before I tear it down completely and fix plenum. I just wasnt sure if that much oil around plug fit the description for blown plenum! Thanks guys.
