    It could be a broken / damaged internal baffle plate .

    If it is broken- good chance the oil regulator in the compressor has bad o-rings now also.

    Refrigerant migration to the compressor will blow the seat off the compressor discharge valve potentially sending pieces into the oil separator--causing noise and/or damage.

    When you state " discharge valve " , what exactly are you stating ? The Trane RTAC200 is an air cooled packaged chiller which employees the use of helical rotor compressors .

    You are correct the RTAC200 is an air cooled chiller that does indeed have two CHHP helical rotor compressors. They have isolation discharge valves (part number VAL07370). I believe the valves are manufactured by Mueller.

    Inside the compressor, sort of below the discharge line connection, behind the internal oil filter. If the oil separator is compromised, then there will be oil and hot discharge gas being sent to the oil line, and hot discharge gas can overheat and trash the o-rings seats employed on the oil regulator valve - they may just call it a oil control valve.
