So first off thank you to everyone who helped out with my last issue. Compressor clutch was bad and now all is good with that. But now I am starting to get a similar sound ever since I changed the oil. Before you ask, all oil levels are good, I checked cold and hot. You know the sound your car makes right after you change the oil and it goes away after the oil pump starts sucking everything up? Yea, if the car is cold, it makes that noise until it warms up, all the time now, including this morning, when I went to lunch, and when I left work. I was thinking maybe oil pump?
