turn off radio& aircond to hear the sound clearly, slow moving around 10-20KMH, for my car can hear from front engine- passenger side

under rare cases your engine oil will be leaking and high fuel consumption, i think you should get confirmation with Proton because no one here know what are the function of OWV, so we cannot theorize the long term/shor term effect, based on kiapreve problem the symptom instead of clak clak sound is oil leaking and high FC.
