You might borrow a rad pump tool & pump it up to 15 lbs when hot to pinpoint where it's coming from. Speedway mtrs has a 6" long 1&3/4" metal hose extension for cheap and drill a hole in it & add a valve stem and a pair of junk rad hoses cut to length & sub it in for your top hose and air chuck pump it up to 15 lbs.

Hey, I was just thinking about doing something like that. I drove the car Saturday for 40 miles and I had a bigger puddle of coolant under it. I noticed that my upper hose was really swollen when I parked it. I had to replace my radiator cap this year as the old one came apart. I bought a 16 pound stock style for a replacement. The new cap does not leak any coolant out of the overflow. But the car runs cool and doesn't overheat.
