Ok,,just had service done on my E30..the technician told me my steering rack is leaking major,,i know the PS fluid resevoir I fill every 4 days or so,,but my question is: will a new rack (did i say Rack?) cost me a bundle? i tried all the stop leaks out there,has helped, but now i know for sure its the rack,,any input would be great,,Ken 90 325ia, 92 325ic
