filament filament all over where shouldnt be, how do I fix this

[Bruce19]

I just finished a 27 hour print. And I have to say it was the "dirtiest" print I've ever had. There was filament pieces all over the bed. During the print, it looked like filament was "leaking" from above the nozzle. When the print was finished I set to find out what's going on. I traced the "leak" back to where tube from cooling fins that goes into heating block. I have the suspected leak area circled in one of the pictures. Other pics show "path" of filament leak. There was NO filament up inside cooling fin. At first thought was I can solder a bead around the tube and heating block until I realized its aluminum and wondered about solder melting temps. So I tossed that idea. So here I am, ANY IDEAS?
