Hello all,
My 2015 has oil on some of the threads of the spark plugs. None in the tubes at all. Does anyone know where I can find a video to repair this? Has anyone done this repair and how difficult is it? It causes misfire under low rpm load
thanks in advance

You have to remove the cam/valve covers to access. Seals come with a cam/valve cover gasket set or iirc, can be purchased seperately.

Thank you for the response! Do you know the difficulty of this? Do I have to mess with the cams at all? Can I just remove a tube once i remove the valve cover? I don‘t see anything anywhere on how to do this

Oil should not cause misfire. It does not conduct. I had '01 and oil was up over the metal part of the plug, so I had to swab it out to change plugs. Not worth fixing as it caused no issue.
Pic of water around the plug and this did not misfire but causes other running issues.

The plug seals are replaced from inside the valve covers once they're removed.

Oil in the valves would cause misfire though correct? The diodes don’t have oil just the thread

Oil/carbon build-up atop the intake valves can cause misfire symptoms. I think you mean "electrodes" not "diodes".

 

[Tfan]

Yes electrodes.

Oil is leaking into the intake valves from I believe the bottom of the tube. The threads have oil. But there is nothing in the top of the tube where the coils sit. I need to remove this tube only. Does it pull out or do I have to go deeper?

Like chartmaker said, you can either replace the spark plug tube seals or not. If just the plug threads are oily and not the business end (electrodes), shouldn't be a misfire cause.

What else could cause that leak?
