Under What Circumstances Should a Cylinder Head Be Replaced?

[McLydia]

If the cylinder head develops cracks, it needs to be replaced, and if the cylinder head becomes deformed, it also requires replacement. The cylinder head is the engine's cylinder cover, and this component is part of the engine's combustion chamber, making it crucial for the engine. Below is an introduction to the relevant content: 1. From top to bottom, the engine consists of the valve cover, cylinder head, cylinder block, and oil pan. Inside the engine, there are components such as the crankshaft, piston, connecting rod, and within the cylinder head, there are intake valves, exhaust valves, and camshafts. Most car engines adopt a double overhead camshaft design, where the cylinder head houses two camshafts—one controlling the opening and closing of the intake valves and the other controlling the exhaust valves. 2. If the cylinder head experiences severe deformation, it must be replaced. A deformed cylinder head can compromise the engine's sealing, leading to issues like air and oil leaks. Similarly, if the cylinder head develops cracks, these can also cause air and oil leakage problems in the engine.
