Hey. Sorry, I'm at RHC all the time. That place is getting busy, and is taking all my time.
It still could be the tube. I had that problem on and off for 3 years before i finally fixed it. It would come and go. In fact, I'd forget all about it, and then get on it at some point and hear it. Other times I could get on it, and not hear it at all. For me, it was the tube going to the head for the #6 cylinder.
