My car has been having trouble lately. I've heard that if I have a blown head gasket, I'll need to have the engine rebuilt. Is this true?

It is possible that you may need to replace your engine block and head if they are both cracked or damaged due to a head gasket failure. This would likely involve replacing the engine as a whole rather than just the head. However, it's important to consult a professional mechanic for more information on what needs to be done.
