You said you found a hole in the S-shaped hose and replaced it... and that worked for a bit. I suspect it just found the next weakest link in the chain.
Take the remaining 3 rubber hoses off the car and carefully look them over, and carefully look at the intercooler for any cracks or splits. You may have to take the bumper cover off to properly see it (easy).
