Can you drive a car with blown head gasket?

Answer 1

Can you and should you are totally different questions. Sure you can drive it if you want to destroy the engine. But you should not unless you wish to destroy the engine. Otherwise, STOP driving this car until you have it repaired.

Answer 2

Sure you can drive it. Know that in doing so you will destroy the engine. Coolant is a horrible lubricant and will destroy the bearings and rings in a very short period of time.
