    Hey everyone, can anyone tell me if my liner protrusions are within spec, can find nothing regarding DD13, plenty on DD15...but not 13.
    I measured all my liner protrusions after installing new liners in my truck, see pics, do they look ok? Can't find min-max specs for dd13's anywhere. Most measurements are coming in at .018-.020 thru out. Is that good? I'm an owner operator doing my own in frame, trying to stay on the road, any help would be great.

    Seems high compared to other engines. Most require clamping the liner down when measuring protrusion. I would clamp and remeasure. If anything else your numbers are consistent across all cylinders which is good.

    Hopefully someone will respond with the correct spec for you. I would guess it will be under .010. Though at the highest.
