@UPALLNIGHT - I note in my original post that compressor on the pictures is not mine. I did all work on the car without evacuation of freon. I went in garage this morning and took apart same compressor just take pictures. This compressor was replaced for a customer by local BMW shop this spring. I just get it from the metal pile to keep it as spare. It has same problem.
