Is it Safe to Drive with a Blown Head Gasket?

head gasket fixThe quick answer? No! A blown head gasket is a major problem for any engine, and one that costs quite a bit to fix mechanically. The head gasket is responsible for creating a seal between your engine block (the lower portion that houses the cylinders) and the head (the upper portion that contains the valves). Your head gasket also acts to channel engine coolant to keep your engine cool during operation. A blown or cracked head gasket can cause one of two problems:

  • It can allow coolant to escape from your engine. The result is a loss in coolant, which can lead to overheating of your engine if you drive it for any length of time. Hot escaping coolant can also cause burns if you’re checking under the hood and can also start a fire, which is why a blown head gasket needs to be treated quickly.
  • It can allow coolant to enter your cylinders. If coolant is mixed in with your engine oil and fuel, the result is the characteristic white smoke you see coming from the tailpipe of a car with a blown head gasket. Too much coolant in your cylinders can lead to severe engine damage quickly, as it keeps your engine oil from lubricating properly.

Most head gaskets don’t blow right away, but instead start as a small leak. It’s important to watch for signs of a blown head gasket, especially in older vehicles. If you notice your coolant level dropping but don’t see an exterior coolant leak, you may have some coolant leaking into your engine. You can also watch for white smoke coming from your tailpipe, another indication that you have a cracked or blown head gasket.
