What are the symptoms of a blown head gasket?
1 Answers
The symptoms of a blown head gasket are: 1. Engine cylinder head leakage: Due to oil and coolant leaks, the leakage point may also exhibit oil and coolant spray, accompanied by a sound of gas mixed with liquid; 2. Reduced cylinder pressure: Compressed gas in the cylinder will leak through gaps into the engine block or other cylinders, ultimately causing unstable engine operation; 3. Oil and coolant leakage: Under the action of the water pump and oil pump, coolant and engine oil generate a certain delivery pressure. If the head gasket is damaged, it will lead to coolant and oil leakage or even mixing, resulting in deterioration of both fluids; 4. Gas entering oil or coolant passages: When high-pressure gas enters the oil or coolant passages, it will affect engine cooling and lubrication, leading to increased engine temperature and accelerated wear of engine components. Additionally, a large number of bubbles can be observed in the expansion tank.
