Why is the radiator still bubbling after replacing the cylinder gasket?

There are several reasons why the radiator still bubbles after replacing the cylinder gasket: 1. Common issues include engine cylinder gasket burn-out and compressor air leakage. A burned-out cylinder gasket can severely deteriorate the engine's working condition, rendering it inoperable and potentially damaging related components or parts. 2. During the engine's compression and power strokes, the upper space of the piston must remain completely sealed to prevent air leakage. If the cylinder head leaks, the compressed high-pressure gas can escape into the cylinder head bolt holes or leak from the joint surface between the cylinder head and the engine block. The leakage site will show light yellow foam, and severe leakage may produce a "hissing" sound, sometimes accompanied by water or oil leakage. Upon disassembly and inspection, significant carbon deposits can be observed on the corresponding cylinder head plane and nearby cylinder head bolt holes. If the engine cylinder communicates with the cooling water jacket or oil passage, yellow-black oil foam may float on the surface of the coolant in the radiator, or water may be visibly present in the oil pan. In severe cases, these leakage phenomena can cause water or oil to appear in the exhaust.
