Three common methods of making gaskets are:

1. Die-Cutting: This involves using a die to cut gaskets from sheets of material, allowing for precise shapes and sizes tailored to specific applications.
2. CNC Machining: Computer Numerical Control (CNC) machines can precisely cut gaskets from various materials, providing high accuracy and the ability to produce complex designs.
3. Water Jet Cutting: This method uses a high-pressure stream of water mixed with abrasive materials to cut gaskets from a wide range of materials, ensuring clean edges and minimal material waste.

Cylinder head water leaks are typically caused by a few key factors: deterioration of the head gasket due to age or overheating, cracks in the cylinder head itself, or improper installation. Corrosion and wear over time can also weaken seals, leading to leaks. Additionally, excessive pressure from the engine or coolant system can exacerbate these issues, resulting in water entering the combustion chamber or escaping externally.
