So here is a new one, I seem to have an oily substance at the end of our Oxford Cryostream. It is greenish in color and I honestly have no idea where it may be originating from. The tubes leading into the head look clean. I first noticed it on the paddle I use to block it when mounting crystals and then noticed on the tip as seen in the picture below. I also wiped it out of the little alignment pin that Oxford provides. The cold stream head is about 23 years old and I think may have been one of the first Series 600 installed in the US. I have a newer one, but need to pump the head out before using it but I really would like to know were the oil maybe from.
