Check this diagram, if the pressure relief valve has too little spring tension or a stuck open piston, it would allow the oil to just recycle back to the pressure pump inlet. Ergo LOW oil pressure and recycling the same oil over and over. So a defective pressure relief valve (low spring tension or stuck open piston), instead of protecting against excessive oil pressure can lead to low pressure and over heating. The poster who claimed fixing his pressure relief valve cured his over heating, may have hit it on the head!
