In short, no, you shouldn’t drive with a blown head gasket. The head gasket separates the cylinder head from the engine block. When this seal breaks, it allows coolant into the engine block. This can lead to a warped cylinder head, warped engine block, internal malfunction, and a overheated engine.

What happens when you have a warped head?

Both warped and pitted or corroded heads can cause just as much damage, and can masquerade as issues with your head gasket. Both problems create sealing issues, which lead to leaks and other damage. That’s why it’s so important to always find the reason your gasket failed. It doesn’t usually just happen on its own.
