Sorry I wasn't around to get this right away. No need for pics, I know exactly what you're talking about.
That'* the heater inlet pipe, and the o-ring has blown. You're going to need to remove the pipe from the car. There'* two bolts into the rear head, the black rubber hose, and the bolt into the LIM. Take the pipe to Napa and get a replacement O-ring, They should have it on the shelf. The O-ring kits in the "HELP!" box do not fit, Don't waste your money on them. Good Luck (Not that you need it)
