i replace the hose too still leaks have another oil cooler that doesnt leak swap it still leaks. from the same spot tho. it leaks from where you bolt it on the bolt there no hole in the line.
You probably should order new copper washers from Mazda. I tried finding them at the autoparts stores (even the hard core ones like A-Line) and they didnt have anything in that size. A hydraulic shop might...
When the copper washers are first used they harden and can't be used again. You can try to clean then up with wet/dry sand paper and oil. Then you have to anneal them by heating them up with a blow torch until they glow dark red then dump them in a bucket of water to cool. Then another quick sanding to clean up the burnt contaminants and oxidation and they'll be good to go.
Here's a video that explains it.
Good luck.
btw, the washers on the oil cooler are aluminum and if you try to anneal them they'll just melt. They dont glow red, they liquify. There are ways to do it but it's pretty specialized.
