What symptoms will appear if the cylinder head gasket of a new Santana is damaged?

The symptoms of a damaged cylinder head gasket in a new Santana are as follows: Gas leakage between adjacent cylinders: Without opening the decompression, when turning the crankshaft, it can be felt that the pressure in both cylinders is insufficient. When starting the engine, there is a phenomenon of black smoke emission, the engine speed significantly decreases, and the power output appears insufficient. Cylinder head gas leakage: The compressed high-pressure gas leaks into the cylinder head bolt holes or escapes from the joint surface between the cylinder head and the engine block. Light yellow foam can be observed at the leakage site. In severe cases of leakage, a "hissing" sound can be heard, sometimes accompanied by water or oil leakage. During disassembly and inspection, obvious carbon deposits can be seen on the corresponding cylinder head plane and the nearby cylinder head bolt holes.
A damaged Santana cylinder head gasket is no small matter. The coolant in the radiator will mysteriously decrease, and the engine temperature gauge will shoot up. Driving becomes extremely laborious, with no acceleration even when the throttle is floored. The most critical issue is white smoke from the exhaust pipe, and milky white foam can be seen when the oil cap is unscrewed. Last week, I helped a neighbor diagnose this exact problem—the idle was shaking like a dance. If not repaired promptly, the engine could suffer from cylinder scoring or even seize up, potentially requiring a major engine overhaul. If you smell burning oil or the dashboard shows an overheating warning, you must stop the car immediately.
