White smoke coming from the tailpipe(s). If you see that, get to a mechanic fast!
To tell if the head is cracked, you have to remove it from the car, so you will replace the head gasket, anyway. Take the head to a machine shop and have it magnafluxed to see if it's cracked.
how can you tell if the head is cracked from the exhaust side
A blown head gasket can have many symptoms including loss of coolant out the tailpipe, mixing of coolant and oil (which makes the oil look something like a chocolate milkshake), loss of power, or low compression in one or more cylinders. A cracked block can also exhibit these same symptoms but is less likely.
Blown head gasket, cracked head, or cracked block.
A car can be driven with a cracked head, but not very far. Once the head is cracked, the engine will start mixing oil and water and it is likely that the motor will lock up.
A cracked/warped head, Blown head gasket, cracked cylinder wall, or cracked/warped intake manifold.
You can't fix a cracked head unless you can weld. it must be replaced with a new head.
