Q: head gasket and timing chain on 2004 Ford Explorer

Rookie cbe0621eac06868b3efe0d8d1d3611e23c60d3114864ea2ec19a68cfbd3eebab
will the car start when it has a blown head gasket. how can you tell the timing chain needs to be replaced.
(1) Answer
Yes, a vehicle will start with a blown head gasket, but will have excessive white smoke/ steam coming from the tailpipe. It is usually accompanied by a rough idle and consuming coolant. A worn timing chain usually makes a rattling noise at idle on this model. It sounds as if the engine needs some major repairs.
