It appears that there is a small leak coming from the pipe that connects the upper radiator hose. The mechanic says it's the O-ring. Well after a week's worth of searching Ford, Lincoln and other vendors, they cannot find the O-ring and the local Ford dealers in and around Los Angeles say that the pipe is obsolete.

Does anyone have an idea how to fix this? Or where can my mechanic obtain an O-ring? His technician is telling him they could try repairing it with silicone but before he does that I told him I would search.

Any advice or vendor sights is most appreciated.
