What are the symptoms of a damaged engine head gasket?

[StTalia]

Engine head gasket damage manifests in the following ways: 1. Cylinder head air leakage: A damaged head gasket compromises the seal between the cylinder head and engine block, resulting in air leakage during vehicle operation; 2. Oil and coolant leakage: The damaged gasket may cause coolant and engine oil to leak, potentially mixing these fluids and causing adverse engine reactions; 3. Gas intrusion into oil/water passages: When high-pressure gases enter oil or coolant passages, this can impair lubrication of internal engine components, potentially leading to elevated engine temperatures, severe component wear, and compromised engine performance; 4. Reduced cylinder pressure: The engine operates abnormally and may exhibit noticeable vibration at idle.
