It was noce to meet you there and had a good discussion. I have plugged the open hole of ail filter jacket. though we have disengaged the pipe, however the tick tick (sound is still there) but reduced around 40%.
I went to my electritition and he told me that this fan does not have oil in it, i intend to get verified from some other person as well in order to be sure about it. i will let you about the oil catch can and fan clutch oil after it IA.
