What is a common symptom of a faulty head gasket?

A common symptom of a faulty head gasket is that engine coolant can leak into the oil or combustion chamber. When the head gasket fails, it can no longer maintain a proper seal between the engine block, cylinder head, and the various fluid passages, which can lead to serious issues.

If coolant leaks into the combustion chamber, it may cause white smoke to emit from the exhaust, indicating that the engine is burning coolant. This can lead to noticeable impacts on engine performance and may ultimately result in overheating, as the cooling system is compromised.

Additionally, if coolant mixes with engine oil, it compromises the lubrication properties of the oil, often resulting in engine damage if not detected and addressed promptly. Recognizing this symptom is crucial for diagnosing a head gasket issue, as it can lead to extensive engine repair or replacement if left unresolved.
