No, you should not drive your car with a blown head gasket. A blown head gasket that is not properly repaired can cause even more damage to your car. If you continue driving it, assuming that it will still run, you can say goodbye to what is left of your motor. Take your car to a reliable mechanic. If it is worth it to repair the vehicle, do it.
