Truck came in blowing coolant from puke bottle. Already deleted, but still had EGR cooler. I verified the cooler wasn't the culprit (yet to see a Cummins EGR cooler be the culprit of cooling system pressuring up).
This truck would bubble all the coolant out at idle, engine cold. After getting the head off, I was surprised to see the cylinder walls in this shape. 135k miles, can't feel the marks with your finger nail, but cross hatch is gone in those areas.
What are your thoughts?
