I would think a ring issue would show on both plugs.

Was there any oil on the plug boot?

Agree and negative, boot was clean. Wish I was driving more so I could put on some miles quicker so I can re-inspect.

kosti365 ...What ever happened with this?

I have #1 cyl doing the same... bottom plug is ugly. Top is normal. I have replaced the plug, all the wires.

When I hold the throttle at 1500 rpm and I can slightly hear a random missfire but not a steady dead cylinder. Going to run some injector cleaner next. Injector or Coil if that doesnt fix it. 156k mi. last 7 years was highway driven, very mild driver. Stuck oil ring?

Hey man this is a longshot but I am having the exact same issue with my 14 raptor , also getting cat efficiency faults. Did you ever find out where the oil leak was coming from ?
