Engine burns coolant, idles smooth,I have replaced head gaskets, intake manifold gaskets, Throttle body gasket, Air intake plenum gasket. What else could be wrong, besides Engine block, Heads, or Intake manifold???:confused:

robert - If there is no external leak the most likely causes are head cracked, defective, wrong, improperly installed intake gasket or head gaskets. You will need to have the heads tested for cracks by a machine shop.
