Signs of a cylinder head leak?

Signs of a cylinder head leak include white smoke coming from the exhaust, which indicates coolant burning in the combustion chamber. You may also notice overheating due to coolant loss, and the engine oil could appear milky or frothy, suggesting that coolant is mixing with the oil. Additionally, a loss of engine power or misfiring can occur, as well as bubbles in the radiator or coolant reservoir. If these symptoms appear, it's essential to have the engine inspected promptly.
