Can I still drive my car with a blown head gasket?

What is a Head Gasket?

Some common signs that you may have a blown head gasket include:



  • Overheating engine

  • Coolant leaks or low coolant levels

  • White, milky-looking engine oil

  • Loss of power or poor engine performance


If you notice any of these symptoms, it's important to have your vehicle inspected by a qualified mechanic as soon as possible.

  • Increased emissions and environmental impact due to the leakage of fluids and gases
