Well I have looked and felt inside the valve cover oil fill and the timing chain seems to be on the sprocket.Is there anything else that I might try to see if the motor is locked up because I cannot get a 1 1/8 socket between the radiator and the pulley.But if the chain has broken would I be able to feel it?There is other issues about working on this engine because it is still under warranty,what might that do?If any one out there has any more info Iwould be very thankful. prestonables@peoplepc.com Thanks James
