Systems and methods of the invention relate to monitoring a change in a rotational speed of a crankshaft to identify a failure related to a crankcase breather valve. A reciprocating compressor can include a detection component that is configured to track a rotational speed of a crankshaft of a compressor to identify a change in rotational speed. In an embodiment, the rotational speed can be monitored while unloaded and/or below approximately 800 Revolutions Per Minute (RPM). Based on a change in a rotational speed of the crankshaft, a controller can be configured to communicate an alert which corresponds to a failure related to the crankcase breather valve.
