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:

  1. Blow-by of the cylinder cover gasket
  2. Faulty discharge valve(s)

Dismantle the cylinder cover to identify the source of the backflow.
