I have an MY94 WRX RA which has a water leak coming from a metal pipe underneath the turbo . There are two pipes that run under the turbo the one thats leaking is the lower one .It starts off as a rubber pipe then changes to metal and it also has a banjo bolt on the end of it. I need to replace this pipe asap. Anyone got any idea what this pipe is called or is it just a water cooler pipe for the turbo. Any help much appreciated.
