Bought a 2002 Durango quad cab 4x4 4.7 automatic yesterday for $800 us. It has a blown head gasket runs but has a loud exhaust leak so I think the head is warped. I was looking for opinions on what other people would do in my position, just do a head swap or do the whole motor fixing the oiling problems associated with this motor. I don't think I'm going to swap motors but machining the motor and full rebuild is not out of the question. what do ya think?
