    My assumption was that it was running richer than the rest, and not an oil consumption issue. Wouldn't oil also cause detonation/knock issues as well?

    At first glance it appears to be carbon fouling, but the picture isn't clear enough to tell. Oil fouling should be shinier, last I recall.

    So... swapping the injectors didn't change anything. Still #3 dirty plug and oil in #3 cylinder.

    My mechanic really wants to get this figured out so he is going to start the tear-down (again) end of this week. I'm assuming the engine is going to have to come out and get torn-down (again). One thing is for sure, I am not using the original machine shop. Probably will contact Arlington, who did my CNC head and see if he wants to make sure my block is 100%.

    This whole thing the last two years has really taken me on a roller coaster. Between this, our cross-coast move, finding a place to live, starting a new job and prepping for our wedding, I am feeling super overwhelmed so I am going to log out of the forums for awhile, take some focus off this car, let the shops do their things and attend fully to the rest of my life activities.

    See you all in the future at some point.

    Really is a shame to see that it is oil again. I was hoping it was the easy fix..

    You take care of yourself. I hope the move and the settling in goes much smoother than the car seems to be

    Update.

    Leakdown was conducted with the cams out. Did leak down with the piston at TDC, fully at the bottom of the stroke and in the middle. Zero leak down on all three.

    Stumped....

    At that point the only thing I could surmise would be an issue with the oil control rings or bore itself , having a spot that is slightly out of round or worn. Other than that, there should be no way oil is getting in there unless the head is lifting/high spot on the deck. Even then would be about impossible to get oil over there before coolant.

    I would be upset too.
