Blown oil cooler line driver side

Hello, my 2007 rx8 with 72k blew a cooler line on the highway....I noticed the red oil light on, but i had good oil pressure& kept driving about 10 miles minding I had pressure.....stopped& put like half a quart of oil i had in it which barely showed on the stick ....put a pint of mystery oil in the gas hoping it would help& drove to get oil .....another 5 miles or so....put like 2 quarts in to top it off ....I didn't want to call a tow truck so I tried to quick epoxy the leak area....a steel line just ahead of the fitting into the cooler.....no way to splice it.....clamped a hose around it & hoped for the best......it still leaked by the way, I just hoped it slowed it so I could drive an hour to get home, which I did.....stopping once to add a quart more.......Is there any hope I could get lucky and not have damaged anything ....having good oil pressure the entire time????? It seems ok ....but I haven't driven it or ordered my new lines as of yet..... also any ideas on where I should buy new lines would be cool......thanks
