Think I'll check that over the weekend. The noise also sounds like something is bouncing around, like metal bouncing in a metal container. When I changed the oil and started it up right after it made the sound the longest, for about 8 seconds. Would a leak in those tubes lend itself to that situation? I also have good oil pressure.
