    Well the head is off! With the exception of cylinder 4 being so clean everything looks pretty good to me. Cylinder walls look good, piston tops aren’t real carboned up and valves all appear to be seated good. Surprisingly the EGR cooler was fairly clean, I mean at least I could see through it. So what’s everyone think? Should I just proceed on with a new head gasket? Anything else I should inspect? IMG_9253.jpeg IMG_9254.jpeg IMG_9255.jpeg IMG_9256.jpeg IMG_9257.jpeg IMG_9258.jpeg

    That engine is the poster boy for a steamed clean piston with its dirty but healthy brothers standing by.

    I would guess your 2014 had a production date of Feb 2014 or later with revised pistons and rings. That alone will keep the egr cooler clear.
