What does a warped head on an engine do?

A warped head on an engine can lead to several serious issues, primarily affecting the engine's ability to maintain proper compression and sealing. This deformation can cause coolant and oil leaks, leading to overheating and potential engine damage. Additionally, a warped head can disrupt the alignment of the engine components, resulting in poor performance and increased emissions. If not addressed, it could ultimately necessitate costly repairs or engine replacement.
