What may be the cylinder cover of the refrigeration compressor overheat?

The main cause for abnormally high temperature of compressor cylinder cover is a backflow of compressed gas into a cylinder and subsequent secondary compression.
This may be due to the following:
- Blow-by of the cylinder cover gasket
- Faulty discharge valve(s)
Dismantle the cylinder cover to identify the source of the backflow.
