1. A system, comprising:

  • a detector that is configured to detect a rotational speed of a crankshaft included in a compressor that provides compressed air and that includes a crankcase breather valve coupled with the crankshaft; and

    a controller having a processor and a memory, wherein the controller is in communication with the detector and configured to determine a change in resistance relating to the crankcase breather valve based at least in part on the rotational speed of the crankshaft that is detected, the controller configured to generate a signal indicative of the change in the rotational speed of the crankshaft,wherein the signal is indicative of at least one of a fault, a failure, or an impending failure associated with the crankcase breather valve; and

    wherein the controller is configured to adjust at least one of a duty cycle of the compressor, a starting torque capability of the compressor, or an unloaded run time of the compressor based at least in part on the signal.
