    Looks exactly like the plugs i just pulled from my 2010 with 135k. My threads were covered in oil too

    have you replaced the pcv valve? I did that at same time, it was original and gunked up. I wonder if it was increasing head pressure helping to blow out that excess oil

    I have not yet gotten to the PCV. I need to do that. Thanks for the idea!

    I don't think it will go closer. I had it on "close".

    From here in Alabama they seem to look A OK. Though I'd be changing them at least by 100k miles. But I realize you're caught guessing on their current mileage.

    For reference. Here are my 5.7L OEM Denso Iridium plugs pulled out at 69,000 miles.Plugs1.jpg Plugs3.jpg
