Hey ....this is not a new problem. When they shifted the top ring to a higher ...hotter ...position on the piston, the ring gap needs to be around .035 inch. If you do not have enough gap the ring ends bump and the crack the top land. New pistons and gap them properly . Don't listen to any of the other crap.
