How does this plug look?
looks just fine to me. I pulled out my original AC delco plugs at 120k miles and they looked just like that, except the tip was a lot smaller, the gap was more like .70.75. Looks normal to me from what i can see.

I think the oil on the threads comes from slight leaks at the valve cover gaskets or from dirt and water that works its wat into the threads.
I also have some oil on my threads usually too.

Yeah my car is a 98, not sure when denso became stock. The part# on the plugs are 41-931 and are no longer made by ACDelco, they were replaced by the ACDelco iridium plugs, dont have part number off hand sorry.
