What are the symptoms of a damaged engine cylinder head?

[Barbosa]

The symptoms of a damaged engine cylinder head include engine weakness, one or two cylinders not working, and blockage in the water passage. Engine weakness: After the cylinder head is damaged, acceleration becomes difficult, and you often feel the engine is weak while driving. Additionally, there may be a leaking sound at the joint between the cylinder head and the cylinder block or in certain areas. One or two cylinders not working: After the cylinder head is damaged, some cylinders may stop working, producing abnormal noises; the radiator's water filler port continuously emits bubbles, and oil droplets may appear on the surface of the coolant; the engine oil turns milky white, and water droplets continuously flow from the exhaust pipe. Blockage in the water passage: If there is accumulated water in the water passage after the cylinder head is damaged, blockage may occur; the cooling fins of the diesel engine cylinder head may also become blocked, causing localized overheating. Overheating in the water cavity area between the intake and exhaust passages can lead to insufficient engine power or even failure to start.
