So I can't figure out what this is but any suggestions would help. Randomly today, the wife calls and says I can hear this sound and it's under the brand new yukon. I said well watch your gages and I will look tonight. Flashforward till dinner and it happens again. So I crawl under it at outback to see this drip (picture attached). All the levels appear to be normal from a quick check also. What in the world could be leaking down to what I would assume is the y-pipe. Also is the y-pipe if that is it really suppose to look like that? Thanks in advance but dinner wasn't going to be the same till I asked someone. Lol
