Causes of lack of compression in the piston

Hello everyone.

I would like to know what are the causes for a piston to normally lose the compression.

Is it true that vehicle overheating can cause compression loss in the piston?

Thanks and greetings !!

The causes of the lack of comprehensive in a cylinder are diverse, you can be, by rings, by oval cylinders, by crooked valves, by valves or by the croad packing.
If it is true that an engine overheating can affect the compression since it can produce a deterioration of the cylinder head packaging, or deformity of it, as well as a deformation of the cylinder and clogging or routing of rings.
