Methods and systems for valve leak simulation

A compressor valve leak detector comprising:

• a bypass block comprising a first passageway and a second passageway defined therein;
• a compressor valve input port in flow communication with said first passageway, said compressor valve input port configured to receive a compressor valve therein, said first passageway at least partially defining a first gas flow path;
• a bypass valve in flow communication with said second passageway, said bypass valve and said second passageway at least partially defining a second gas flow path;
• a gas temperature transducer coupled to said bypass block for measuring a temperature of gas within the first gas flow path;
• and
• a valve temperature transducer coupled to said bypass block for measuring a temperature of gas within the second gas flow path, wherein the temperature of gas measured by each of said gas temperature transducer and said valve temperature transducer facilitate the detection of a compressor valve leak by a diagnostics system.
