You may need to replace a piston head if you notice significant loss of compression, which can lead to poor engine performance and increased oil consumption. Additionally, visible damage such as cracks, scoring, or excessive wear can indicate that the piston head is compromised. Unusual noises from the engine, such as knocking or tapping sounds, can also suggest piston issues. Regular inspection and monitoring of engine performance are key to identifying when a replacement is necessary.
