What Does a Cylinder Head Gasket Do?
The cylinder head gasket creates a seal between the cylinder head and engine block. It keeps combustion pressure inside the cylinders while separating cooling passages from the combustion chamber.
A damaged head gasket can result in compression loss, cooling system leaks, water intrusion, overheating, hard starting, or poor engine performance.
When Should a Head Gasket Be Replaced?
- During cylinder head removal
- When repairing overheating damage
- When rebuilding a powerhead
- After detecting water intrusion into a cylinder
- When compression loss indicates gasket failure
