Again, it seems like Remeshing is not behaving correctly. In the Mesh Method Settings, I would suggest enabling the Region Face remeshing, this will allow remeshing of faces adjacent to the moving boundary (piston).

Are you using Smoothing as well? Smoothing and Remeshing are typically used together.
