I know the head has to come off as it is an interference motor, the reason for my question was to help determine what failed with the limited information at this point, engine is not seized, all rollers turn, water pump turns, injection pump pulley turns, cam pulley locked up. I was told that its usually some ribs on the belt that break off rather than the belt snapping in half with no ribs broken off? belt was about 2 years old with 30k tops on it, head is Chinese and was suspect initially but now so is the belt, not sure of the make on the belt? The car ran better than ever prior to this failure primarily due to the new injection pump, I was ready to blame all on the head but now i'm leaning towards the belt but won't know until I pull the valve cover, and the total damage after pulling the head. Belly pan and all shields in place 370k on car, less than 50k on head.
