will the car start when it has a blown head gasket. how can you tell the timing chain needs to be replaced.
head gasket and timing chain on 2004 Ford Explorer
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.
