Check the porcelen on each plug make sure you dont have any burn marks.
Dose it happen in cold and wet or hot dry conditions?

113k miles. The build up makes sense since I seem to be losing oil, but it's not leaking out onto the ground so it's going somewhere.
Happens in all weather though it's mostly warm to hot here all year (Florida).
Here's a picture of all the NGK plugs I took out. Most had some oil on it but that one I posted in the OP was the worst of them.
Oops... I guess just 7 of them. Didn't take them all out of the trash I guess lol. Looks like some have burn marks on them.
