What problems can arise from running a reciprocating compressor without a load for an extended period of time?

Model: 4M80. What problems can occur if a no-load test run is carried out for an extended period of time with the air valve not installed?
The purpose of the no-load test run of the compressor is to ensure a tight fit between the packing in the metal stuffing box and the piston rod through relative movement; to ensure proper operation of the moving components such as the crankshaft and connecting rods through rotation. It also serves to check whether the lubrication systems (the circulating oil lubrication system and the oil injection systems for the stuffing box and cylinders) are functioning properly during the compressor’s operation. Resolve the issues identified during the no-load test to create conditions for the compressor to proceed to the load test. The commissioning time is generally around 24 hours. No-load testing is mainly carried out to create the conditions for load testing, which usually takes about 72 hours. There shouldn’t be any problem with the idle time being long! I’m not sure what specific situation you’re facing right now; please describe it in detail!
During the first test run, observe the changes in oil quality during the no-load phase; once the color darkens, stop the machine and replace the lubricating oil. Otherwise, it will cause wear to the bearing shells
